Historically, Argentine presidents often face high disapproval ratings during periods of structural adjustment. Javier Milei’s trajectory from 50.7% (Oct 2024) to 59.3% (April 2026) follows a pattern of ‘bitter medicine’ policies impacting consumer sentiment. In Mexico, the presidency often enjoys a high-approval ‘honeymoon’ period; Sheinbaum’s initial ratings above 80% in early 2025 were exceptional. The subsequent decline to 51% approval and 36% ‘Malo/muy malo’ by April 2026 represents a return to mean for Mexican politics, where economic performance and corruption are historically the primary drivers of negative sentiment. The gap between these two leaders is idiosyncratic, reflecting the massive divergence between Argentina’s extreme inflation history and Mexico’s relatively stable, though currently cooling, economic environment.
My prediction for the Milei-Sheinbaum gap is based on a synthesis of recent polling trends, macroeconomic indicators, and the historical behavior of government disapproval ratings in Argentina and Mexico. The primary anchor for this forecast is the April 2026 AtlasIntel report, which showed Milei at 59.3% and Sheinbaum at 36.3%, a gap of 23.0 percentage points.
In Argentina, President Milei’s ‘Malo/muy malo’ rating has risen steadily from 50.7% in late 2024 to nearly 60% in April 2026. While his administration has achieved significant success in reducing inflation—dropping from year-over-year peaks near 300% to around 32%—this hasn’t yet translated into improved public sentiment. Consumer confidence remains in the bottom quartile of its 25-year history, and demonstration activity has spiked. This suggests Milei’s disapproval is likely to remain high, though it may be approaching a natural ceiling near 65%, common in highly polarized political environments.
In Mexico, President Sheinbaum’s disapproval has risen from historical lows below 20% early in her term to 36.3% in April 2026. This trend reflects the typical erosion of a presidential honeymoon, now exacerbated by a 0.8% GDP contraction in Q1 2026 and persistent public concern over corruption and security. Since Sheinbaum’s disapproval has more room to grow compared to the relatively ‘saturated’ disapproval for Milei, the most likely path for the gap is a slight narrowing or stabilization.
I weighted the current gap of 23.0 heavily but adjusted the forecast slightly downward to 21.5 to reflect the faster rate of change currently seen in Mexico’s disapproval ratings. The 50% HDI of 18.50 to 25.50 accounts for the combined margin of error of the two polls (approximately ±2.2 percentage points) plus two to three months of potential political volatility. I considered a scenario where Milei’s reforms face a major social breaking point, pushing the gap toward 30, but the current stability in Argentine inflation makes a sudden vertical spike in disapproval less likely than a slow grind. Conversely, a stronger-than-expected Mexican economic recovery could keep Sheinbaum’s ratings lower, maintaining a wider gap. Given the monthly cadence of AtlasIntel, the July 2026 report (published in late July or early August) will be the final determinant.
Question: which AtlasIntel Latam Pulse same-month Argentina/Mexico pair published/verifiable by 2026-08-12 will give the Milei minus Sheinbaum “Malo/muy malo” gap, and what is that gap likely to be? The last non‑qualifying baseline is April 2026 (Milei 59.3%, Sheinbaum 36.3%, gap +23.0 pp) and AtlasIntel has released roughly monthly late‑month waves, so the resolving pair will most likely be July 2026 (June if July isn’t verifiable by the deadline). Forecasters agree the best mechanical approach is to track the two component series separately: Milei’s negatives are very high and have been rising but decelerating (now ~59%), while Sheinbaum’s negatives have accelerated recently (up to 36.3%), so April’s narrowing likely reflects Sheinbaum catching up rather than a collapse in Milei’s negatives. The consensus centers the gap in the low‑to‑mid‑20s (roughly 19–22 pp median), with most weight (~80%) in a roughly 15.5–25.5 pp band and an expected one‑sigma uncertainty of about ±4 pp; tail outcomes (very small <13.5 or very large >30.5 gaps) are judged very unlikely. Key caveats are the short four‑month sample, polling/house/mode effects, and near‑term political/economic shocks in Argentina (inflation, reforms, LIBRA) and Mexico (Q1 contraction, security/trade frictions) that could push either component several points. Finally, publication timing is material—if July is late past the cutoff (estimated ~25% chance by one forecaster), June would resolve and the gap would probably be a bit wider.
Forecast: Probability distribution:
Two analysts (2 and 3) provided direct AtlasIntel PDF citations for Feb–Apr 2026 “Malo/muy malo” government evaluation values. These imply a recent gap (Milei − Sheinbaum) in the mid‑20s: about 23.9 pp (Feb), 25.7 pp (Mar), and 23.0 pp (Apr). That anchors the forecast much more strongly than generic approval commentary.
The resolution will use the latest same-month Argentina+Mexico pair published after April 2026 and before 2026-08-12 12:00 UTC (most likely the July 2026 pair released in late July; possibly June if publication is delayed). Over a ~2–3 month horizon, both countries’ “malo/muy malo” can move several points month-to-month; April showed that Mexico can jump notably. The gap therefore could narrow (if Sheinbaum’s negatives rise faster than Milei’s or Milei improves) or widen (if Argentina experiences a new shock while Mexico stabilizes).
Synthesis of the four forecasts: Forecasters 2 and 3 center tightly around 23–25 with moderate tails; Forecasters 1 and 4 allow more downside (gap narrowing substantially). I keep the median near the observed 23 pp, but widen the lower tail somewhat (relative to 2/3) to reflect the realistic possibility of a Mexico-driven narrowing, while keeping the upper tail below ~40 as a low-probability scenario rather than a central one.
An amateur forecast would likely (a) reuse the latest observed gap (~23 pp) with an overly narrow interval, or (b) rely on generic approval narratives without anchoring to the specific “malo/muy malo” series used for resolution. This forecast is improved by explicitly anchoring to the cited Feb–Apr AtlasIntel “malo/muy malo” values (gap consistently mid‑20s), then adding calibrated uncertainty for the specific 2–3 month ahead “latest pre-deadline pair” mechanism (including publication-month uncertainty and plausible month-to-month swings). Confidence is moderate: we have strong recent anchors, but country-specific shocks can still move the gap by ~10+ pp over a few months.
Forecast rationale (numeric):
— Iteration 1 — Across the forecasts, the core reasoning is highly consistent:
Both rationales stress wide uncertainty because:
The shared view is that the Milei–Sheinbaum “malo/muy malo” gap will likely stay around 23 pp, with Milei still substantially more negatively rated than Sheinbaum, and with uncertainty driven mainly by short-term volatility and timing of the latest AtlasIntel release.
— Iteration 2 — Across the forecasts, the main reasoning is that the Milei − Sheinbaum “malo/muy malo” gap should remain clearly positive and likely in the mid-20s percentage points in the latest AtlasIntel Latam Pulse pair before the cutoff.
Taken together, the forecasts argue that the latest AtlasIntel pair before the cutoff will probably show Milei with substantially higher “malo/muy malo” ratings than Sheinbaum, with the gap most likely landing around 25–27 percentage points, and only unusual political or polling shocks likely to push it far outside that range.
— Iteration 3 — Across the forecasts, the core reasoning is broadly aligned:
Overall, the forecasts collectively suggest that the latest pre-deadline AtlasIntel pair will likely still show a clear Milei-over-Sheinbaum gap, but somewhat smaller than the current 23 pp reading.
Summary of Forecasting Rationales
Baseline and Timeline Forecasters universally anchor their analysis on the most recent spring AtlasIntel Latam Pulse reports, noting that the gap is currently defined by Javier Milei’s significantly higher negative evaluations compared to Claudia Sheinbaum’s. The resolution is broadly expected to rely on the July edition of the report, leaving a short two- to three-month window for public sentiment to shift.
Javier Milei’s Trajectory (Argentina) Milei faces intense domestic headwinds driven by austerity fatigue, a stagnant real economy, recent cabinet scandals, and the painful phase-out of energy subsidies hitting during the Southern Hemisphere’s winter. Despite these challenges, forecasters highlight a strong “ceiling effect” on his disapproval. Because the Argentine electorate is highly polarized and his core, anti-establishment base remains fiercely loyal, Milei has virtually exhausted his pool of neutral voters. Consequently, his negative ratings are nearing a structural peak and have very little room to climb further.
Claudia Sheinbaum’s Trajectory (Mexico) In contrast, Sheinbaum is experiencing the erosion of her administrative honeymoon phase. Her negative ratings have substantial “runway” to increase as neutral voters react to compounding crises. Forecasters point to escalating cartel violence, sluggish economic growth, and diplomatic anxiety surrounding the upcoming USMCA trade review as primary drivers for rising disapproval. However, some note that Mexico co-hosting the FIFA World Cup could generate a temporary “rally ‘round the flag” effect, potentially buffering her against steeper polling declines.
Methodological Factors Several rationales emphasize the idiosyncrasies of AtlasIntel’s Random Digital Recruitment (RDR) methodology. Because the polling is conducted online, it is highly sensitive to short-term news cycles and tends to capture middle-class and independent voter frustration much faster than traditional face-to-face polling. Forecasters note this methodology structurally undersamples rural demographics, which acts as a bearish amplifier on Sheinbaum’s negative ratings by missing elements of her core party base.
Expected Gap Dynamics Overall, the rationales project that both leaders are facing domestic pressures that will push their negative evaluations upward simultaneously. However, because of the structural asymmetry—Milei’s disapproval is bottlenecked by a hard ceiling, while Sheinbaum has a larger reservoir of neutral voters who can still turn against her—the consensus expects the gap between the two leaders’ negative ratings to either remain stable or slightly narrow.

The research analyzes the “Milei − Sheinbaum ‘Malo/muy malo’ gap” using data from the AtlasIntel Latam Pulse survey conducted in April 2026. In Argentina, President Javier Milei’s “malo/muy malo” rating reached 59.3%, marking the lowest evaluation since he took office in December 2023. The survey indicated a significant increase in negative perceptions of his government, with a monthly worsening trend. In contrast, while specific “malo/muy malo” figures for Mexican President Claudia Sheinbaum were not fully disclosed, her overall approval rating was 50.7%, with a noted increase in negative perceptions. The research estimates Sheinbaum’s “malo/muy malo” rating to be in the mid-30s to low-40s range, leading to a projected gap of approximately 23 percentage points between the two leaders.
The study further discusses trends and projections for both leaders leading up to the July 2026 report, suggesting that Milei’s negative trajectory could push his “malo/muy malo” rating to around 65%, while Sheinbaum’s could rise to approximately 45-48%. The analysis highlights the potential for the gap to widen modestly, with a central estimate for the gap in the range of 20-27 percentage points, contingent on the economic conditions in both countries. The research emphasizes the importance of obtaining the precise “malo/muy malo” figure for Sheinbaum to refine the forecast.

Argentina (Milei) — April 2026:
Mexico (Sheinbaum) — April 2026:
Estimating Mexico’s “malo/muy malo”: Given that Sheinbaum’s disapproval is ~42.7% and the government evaluation “malo/muy malo” category often tracks somewhat below outright disapproval (as seen in Argentina where disapproval is 63% vs. malo/muy malo at 59.3%), Mexico’s “malo/muy malo” likely sits in the mid-30s to low-40s range. If we estimate roughly 35–38% (consistent with her still-strong overall standing and the 4.6 pp increase noted), the April 2026 gap would be approximately 59.3 − ~36 ≈ 23 pp, though this estimate carries meaningful uncertainty without the exact published figure.
Argentina “Malo/muy malo” trend:
Mexico trend:
The question resolves on the latest pair published before August 12, 2026, which will most likely be the July 2026 reports (typically released in the final days of each month). Key factors:
Milei’s trajectory is sharply negative: His disapproval hit record highs every month in recent data. Argentina’s October 2026 legislative elections loom, and economic indicators (consumer confidence at −32, 53.7% saying income doesn’t cover basic expenses) suggest continued erosion [7][8]. “Malo/muy malo” could plausibly reach the low-to-mid 60s by July if the trend continues.
Sheinbaum is declining but from a higher base: Her approval remains strong by regional standards (~50.7%), but the 3-month declining trend and rising “malo/muy malo” suggest gradual deterioration. Corruption, insecurity, and inflation pressures are persistent [4][5].
If both trends continue at recent rates:
No prediction markets were found specifically trading on this AtlasIntel Latam Pulse gap metric.
Based on the April 2026 data, the gap appears to be in the low-to-mid 20s (roughly 21–25 pp). Given both leaders’ declining trends but Milei’s more severe deterioration, the gap could widen modestly by the time the July 2026 pair is published (the most likely resolution pair). A reasonable central estimate for the resolution value would be in the range of 20–27 pp, with higher values more likely if Argentina’s economic situation continues to worsen faster than Mexico’s. The exact April baseline for Mexico’s “malo/muy malo” (which I could not fully verify) is the key uncertainty—obtaining that figure from the AtlasIntel website directly would significantly sharpen any forecast.
I need to search for more specific data to verify my forecast and address any gaps in the analysis.
Excellent! I found a crucial data point. Let me fetch more details to verify the exact figures:Now I have concrete April 2026 data.

Let me search for any more recent data (May 2026 or later) that might be available.The most recent data is still from April 2026. Let me now reconsider my forecast with the critic’s points in mind.
1. Baseline Uncertainty - RESOLVED: The critic was right to flag this, but I now have the exact figures. Mexico’s “malo/muy malo” is 36.3%, not the estimated ~36% used in the original research. The April gap is precisely 23.0 pp, not an uncertain estimate.
2. Trend Inconsistency - VALID CONCERN: The critic correctly noted that if Sheinbaum’s malo/muy malo rose 4.6 pp in April while Milei’s rose 1.9 pp, continuation would narrow the gap. However, I have several considerations:
3. Ceiling Effects - PARTIALLY VALID: Milei at 59.3% does face some ceiling resistance, but there’s still meaningful room to grow toward 65-70%. The core ~30% support may be relatively stable, but the movement from 59% to 65% is plausible.
4. Middle Percentile Width - VALID: I agree my 50% CI (21-26, or 5 pp span) was too narrow given 3 months of projection.
| Scenario | Milei | Sheinbaum | Gap |
|---|---|---|---|
| Sheinbaum continues at 4.6pp/mo, Milei at 1.9pp/mo | 65% | 50% | 15 pp |
| Both moderate: Milei +1.5pp/mo, Sheinbaum +2pp/mo | 64% | 42% | 22 pp |
| Milei accelerates, Sheinbaum stabilizes | 68% | 38% | 30 pp |
| Both stabilize near April levels | 61% | 38% | 23 pp |
| Major reversal for Milei, crisis for Sheinbaum | 55% | 45% | 10 pp |
Given the World Cup starting in June (potential positive for Mexico), continued Argentine economic struggles, and the documented convergence trend, I now see the median closer to 20-21 pp, with wider uncertainty bands.

Looking at this forecasting question, I need to analyze the expected gap between Milei’s and Sheinbaum’s “Malo/muy malo” ratings from the AtlasIntel Latam Pulse reports.
(a) Time left: Approximately 3 months until resolution (August 12, 2026). The most likely resolution pair will be the July 2026 reports, typically published in late July.
(b) Outside view / Base rates:
(c) Inside view evidence:
(d) Outcome if nothing changed: Gap of ~23 pp (based on April estimate: 59.3% - ~36%)
(e) Outcome if trends continued:
(f) Expert/market expectations: No prediction markets found on this specific metric.
(g) Low outcome scenario: Milei’s IMF-backed reforms show concrete economic improvements (inflation reduction, peso stability), reducing his “malo/muy malo” to ~55%. Sheinbaum faces escalating cartel violence or US trade conflict, pushing her “malo/muy malo” to ~45%. Gap narrows to ~10 pp.
(h) High outcome scenario: Argentina spirals into deeper economic crisis (debt default, hyperinflation fears), pushing Milei’s “malo/muy malo” to 70%+. Sheinbaum’s administration stabilizes or recovers modestly. Gap widens to ~35-40 pp.
Rationale: Starting from the base rate of a ~22-23 pp gap in April 2026, I note significant uncertainty in:
Both leaders are trending negative, but at potentially different rates. The most likely scenario is that the gap remains relatively stable (20-25 pp) with slight narrowing possible if Sheinbaum’s deterioration outpaces Milei’s. However, Argentina’s more severe economic indicators suggest Milei could deteriorate faster, potentially widening the gap.
I’m centering my forecast around 22 pp with meaningful uncertainty in both directions, respecting the question creator’s bounds of 5-40 pp while allowing for tail scenarios.

Agent Forecast (discrete, confidence: medium)
Base Rate: Historical 2026 Milei-Sheinbaum ‘malo/muy malo’ gap from AtlasIntel/Bloomberg Latam Pulse: Jan ~20 pp, Feb ~24 pp, Mar ~26 pp, Apr 23 pp. Both trends point toward continued narrowing in May-July 2026 due to Sheinbaum’s accelerating disapproval (corruption scandals, Q1 GDP contraction, narco indictments) and Milei’s decelerating disapproval growth (approaching potential ceiling).

Reviewer (reasoning)
The draft’s core weakness is its reliance on a three-month linear trend extrapolation from just two month-to-month changes, which is too thin a basis given known poll volatility and margins of error. It also ignores any available May or June data for Argentina and Mexico that could materially shift the trajectory, and it fails to incorporate typical poll sampling error or potential structural breaks (e.g., major policy announcements) between now and July. The resulting distribution is likely over-narrow and underestimates true uncertainty.
Objections:
Reviewer (calibration)
The forecast relies too heavily on a simplistic linear extrapolation of recent ‘Malo/muy malo’ trends for Milei and Sheinbaum, without adequately accounting for the underlying political and economic factors driving public sentiment. The projection of Sheinbaum’s disapproval reaching only 44-46% contradicts the stated ‘accelerating’ trend from a +4.6 pp/month increase, suggesting an inconsistent application of the trend logic. This results in a projected gap that is likely too wide.

Adjustment Rationale:
Held firm on interpretation (April 2026 pair does not qualify per resolution criteria ‘after April 2026’ — confirmed by web search showing no May 2026 AtlasIntel data exists yet as of today, May 11, 2026). Adjusted in two ways: (1) Calibration reviewer correctly identified internal inconsistency — if Sheinbaum’s ‘malo’ is accelerating (+4.6pp in April), a 3-month projection should put her closer to 47-49% rather than 44-46%, narrowing the expected gap toward 15-17 pp. Shifted central tendency from ~20 to ~19 pp. (2) Reasoning reviewer correctly noted distribution was too narrow given polling MOE (~±3-4pp compound) and 3-month political volatility — widened spread substantially, with more mass on 12-17 (Sheinbaum-accelerates scenario) and 25-30 (Milei-stabilizes scenario). Fact-checker objection rejected: the ‘after April 2026’ exclusion is directly in the resolution text. Ensemble signal of 11.4% (if interpreted as P(gap in 18-22 narrow band) ≈ 39% in my distribution, or as single most-likely bin) is broadly consistent with the widened distribution centered at 19-20.

Model’s Answer: Step one is anchoring on the best hard evidence we have. The latest verifiable AtlasIntel benchmark in the research is the April 2026 pair, with Milei at about 63.0% “Malo/muy malo” and Sheinbaum at about 43.0%, implying a gap near +20 pp. April itself does not qualify for resolution, but it is the closest direct read on the exact metric.
Step two is thinking about which month is most likely to resolve the question. Since Latam Pulse is usually published near month-end, the resolving pair is most likely the July 2026 Argentina and Mexico reports, published in late July and still before the August 12 deadline. There is some chance the latest qualifying pair ends up being June or even May if publication or verifiability gets messy, but that does not radically change the baseline because the horizon is only a few monthly releases.
Step three is adjusting for trend versus stickiness. Milei’s negative evaluation was rising sharply into April. Sheinbaum’s negative evaluation also rose, but from a lower base. Public-opinion series like these do move, but over a two- to three-poll horizon they are usually more sticky than dramatic unless there is a major shock. So the April gap around +20 is a stronger base case than any straight-line trend extrapolation.
Step four is source weighting. I put the most weight on the existence and timing of official AtlasIntel Latam Pulse pages, substantial but lesser weight on media reports quoting the exact “malo/muy malo” values, and very little weight on social posts. The official pages matter most for cadence and verifiability; the media quotes matter for the exact percentages where the official summaries in the research were thinner.
Step five is identifying the assumptions that could most change the forecast. The first assumption is that the resolving pair is July 2026 rather than an earlier fallback month; I think there is about a 20% chance this is wrong, but it only modestly changes the distribution. The second assumption is that April’s roughly +20 gap was not a one-off distortion; I assign about a 30% chance that this baseline is misleading enough to matter materially. The third assumption is that no large asymmetric shock hits one leader but not the other before the resolving poll; I put that failure probability around 25%. I widen the tails to reflect all three.
A low outcome would most likely come from some combination of Milei improving on inflation or growth while Sheinbaum is hit by a serious corruption or security deterioration inside AtlasIntel’s fieldwork window. I think single-digit gaps are possible but clearly not the base case. I put roughly a 10% chance on 12 pp or lower, about a 1% chance on 7 pp or lower, and the required 0.1% tail below 4.5.
A high outcome would most likely come from Milei’s “malo/muy malo” moving further into the high 60s or low 70s while Sheinbaum either stabilizes or recovers into the mid-30s on the negative side. That would push the gap into the 30s. I think outcomes above 33 are possible but still secondary. I put about a 10% chance on 33 pp or higher, around a 1% chance on 40 pp or higher, and a very small tail beyond 40.5.
Overall, my median stays close to the April read, slightly above it, because Milei’s negatives were already very elevated and Sheinbaum’s were rising too. That yields a center around 21 pp, with a fairly broad but not extreme spread.

Forecast: median = 21.5757
Milei’s Approval Trend: Milei’s “malo/muy malo” ratings have shown a significant rise over the past months but are now decelerating, suggesting a potential ceiling effect around 60-62%.
Sheinbaum’s Recent Spike: Sheinbaum experienced a notable increase in negative ratings in April, but whether this is a sustained trend or a temporary spike is crucial. If it continues, the gap will narrow; if it reverts, the gap will widen.
Economic Conditions: Argentina’s inflation and political scandals are key factors influencing Milei’s ratings. A stabilization in inflation could limit further increases in negative perceptions.
Security Issues in Mexico: Ongoing violence and security concerns in Mexico could further impact Sheinbaum’s ratings. If these issues persist, her negative evaluations may rise, affecting the overall gap.
Methodological Stability: The AtlasIntel polling methodology has shown consistent results, but any shifts in how data is collected or weighted could lead to unexpected changes in the gap.
Timeframe Sensitivity: With the next data release expected in July 2026, the forecast is sensitive to developments in both countries over the next few months, particularly regarding economic and security conditions.

Rationale: Summary The baseline gap between Javier Milei’s and Claudia Sheinbaum’s “Malo/muy malo” (bad/very bad) government evaluation ratings stood at roughly 23 percentage points as of April 2026. This gap stems from Milei’s high disapproval of 59.3%, reflecting widespread discontent amid ongoing economic adjustments in Argentina, compared to Sheinbaum’s 36.3% disapproval in Mexico. The gap has recently narrowed from approximately 28 points in March 2026, primarily driven by a 4.6-point spike in Sheinbaum’s disapproval following recent scandals and economic discontent, while Milei’s rating has remained flat. The central estimate of 22 percentage points projects that this baseline will hold relatively stable in the polling published through July 2026. This assessment assumes the recent surge in Sheinbaum’s disapproval will neither fully reverse nor drastically accelerate, and balances the potential for incremental improvements in Argentina against inherent polling volatility.

Key Uncertainties
AtlasIntel’s publication pattern makes the July 2026 country-month pair the most likely one used for resolution. Official Atlas pages show the January 2026 Latam Pulse reports published on January 22, the February reports on February 26, the March reports on March 26, and the April Argentina/Mexico reports on April 29-30. Historical pages also show June 2025 reports publishing on July 8, July 2025 on July 31, and August 2025 on August 28. So by the August 12, 2026 deadline, the latest usable pair is very likely the July 2026 Argentina/Mexico pair, whether it appears in late July or slips into early August; a true August 2026 pair before the deadline looks unusual. I treat annulment risk as negligible enough not to model separately in the numeric array. (atlasintel.org)
The current official base is April 2026. In the AtlasIntel PDFs, Milei’s government is at 59.3% Malo/muy malo in Argentina and Sheinbaum’s government is at 36.3% in Mexico, a 23.0-point gap. The immediately prior pairs were 53.1% versus 29.2% in February and 57.4% versus 31.7% in March, which works out to gaps of 23.9 and 25.7 points. So the recent AtlasIntel range for this cross-country gap is already tightly centered in the low-to-mid 20s, even though both leaders have been trending worse. The April fieldwork was April 24-28, 2026, with samples of 4,844 in Argentina and 2,948 in Mexico. (cdn.atlasintel.org)
For Milei, the directional pressure is still negative, but I do not think the February-April worsening should be linearly extrapolated. AtlasIntel shows Malo/muy malo moving 53.1% to 57.4% to 59.3% from February through April. Bloomberg and Reuters both tied the March-April weakness to corruption allegations, unemployment, and slower growth. But there are also counterweights: Reuters reported Argentina’s IMF review advancing in mid-April and Fitch upgrading the sovereign on May 5 while citing stronger political backing after the October 2025 midterms. My inference is that Milei’s July Malo/muy malo number is more likely to level off in the low 60s than to keep rising at the full January-April pace. (cdn.atlasintel.org)
For Sheinbaum, the trend is also negative, and unlike Milei there is still plenty of room for disapproval to rise from a lower base. AtlasIntel shows Malo/muy malo at 29.2% in February, 31.7% in March, and 36.3% in April. Bloomberg said her April approval hit the lowest point of her term amid economic concerns. Reuters reported a slight first-quarter contraction, inflation still above target though easing in April, and a new Morena split after U.S. cartel-ties charges against Sinaloa figures. My base case is continued slippage into the high 30s or around 40 by July, but not an immediate jump into the high 40s. (cdn.atlasintel.org)
Putting those pieces together, I expect the July 2026 pair to land near Milei low-60s bad/very bad and Sheinbaum high-30s to about 40 bad/very bad, leaving a central gap around 22-23 points. I keep the mean close to the current 23-point gap because both leaders are worsening at the same time, so a lot of common anti-incumbent pressure cancels in the difference. AtlasIntel’s stated April margins of error are about plus/minus 1 point in Argentina and plus/minus 2 points in Mexico; combining them in quadrature gives roughly plus/minus 2.24 points of sampling uncertainty for the gap before adding several months of political-path uncertainty. I therefore encode the forecast as a fat-tailed mixture centered at 22.62 points, with 23 as my single most likely rounded outcome and most of the distribution mass in roughly the mid-teens to around 30. (atlasintel.org)
AtlasIntel has already published Argentina and Mexico Latam Pulse country reports for January 22, February 26, March 26, and April 29/30, 2026. Given that cadence, the latest qualifying pair before 2026-08-12 12:00 UTC is most likely the July 2026 pair, with a smaller fallback chance of June or May if July is delayed or not verifiable. Because the output schema has no annulment bucket, my numeric distribution is effectively conditional on a resolved numeric outcome; I think annulment risk is low given the regular monthly publication pattern. (atlasintel.org)
The official AtlasIntel ‘Malo/muy malo’ readings for 2026 so far are: Milei 47.6 in January, 53.1 in February, 57.4 in March, and 59.3 in April; Sheinbaum 27.3 in January, 29.2 in February, 31.7 in March, and 36.3 in April. That implies monthly gaps of 20.3, 23.9, 25.7, and 23.0 points respectively. So the key empirical fact is that both leaders’ negative evaluations have been rising, but the bilateral gap itself has stayed in the low-to-mid 20s rather than trending sharply upward. (cdn.atlasintel.org)
For Argentina, I see mixed forces. Reuters reported in late March that corruption allegations were hurting Milei’s popularity. At the same time, official INDEC data showed March CPI at 3.4%, while the February EMAE activity estimate was weak at -2.1% year over year and -2.6% month over month seasonally adjusted. There is also an offsetting positive macro narrative: Reuters reported on May 5 that Fitch upgraded Argentina to B- and said it expected 3.2% growth in 2026. My synthesis is that Milei’s ‘bad/very bad’ share is still more likely to drift higher than to reverse sharply lower, but the Jan-Apr jump should decelerate because the series is already near 60% and some reform/economic credibility remains in place. (investing.com)
For Mexico, the recent direction is also pretty clear. Bloomberg’s March coverage said Sheinbaum’s approval fell to the lowest of her term on crime fears, and Bloomberg’s April coverage said approval fell again as economic concerns mounted. Official data are not especially supportive: INEGI’s timely estimate showed Mexico’s GDP down 0.8% quarter over quarter in the first quarter of 2026, and INEGI reported April 2026 inflation at 4.45%. Reuters also reported new strains inside Morena after U.S. cartel-linked accusations against politicians. Taken together, that makes a further rise in Sheinbaum’s ‘Malo/muy malo’ share into the high 30s or low 40s by summer more likely than a sharp rebound. (bloomberg.com)
Quantitatively, I treated the resolving month as a mixture: May 2%, June 8%, July 90%. Within each scenario I modeled Argentina and Mexico as separate normal forecasts, then took the difference. I centered Argentina around roughly 60-62 by summer and Mexico around roughly 38-40, with widening uncertainty to absorb both real opinion movement and ordinary poll noise. That produces mean gaps of about 22.6 for a May fallback, 22.3 for a June fallback, and 22.0 for the most likely July pair.
Bottom line: my point forecast is 22 percentage points. The highest-probability rounded outcomes are in the low 20s, with most of the mass roughly from the high teens to the upper 20s. I leave only small tail probability below 10 or above 35, because while both series are moving against the incumbents, the observed AtlasIntel gap has so far been fairly stable around the low-to-mid 20s rather than exploding wider.
As of Monday, May 11, 2026, the latest qualifying pair available is April 2026. AtlasIntel’s April Argentina report shows Milei at 59.3% Malo/muy malo, and the April Mexico report shows Sheinbaum at 36.3%, so the observed gap is 23.0 pp. AtlasIntel has been publishing Latam Pulse regularly; recent country reports were out on Jan. 22, Feb. 26, Mar. 26, and Apr. 29-30 in 2026, while 2025 June and July reports were published on Jul. 8 and Jul. 31. That makes a July 2026 pair before the 2026-08-12 12:00 UTC deadline very likely, so I treat annulment risk as de minimis and effectively forecast a numeric July-pair resolution. (cdn.atlasintel.org)
The main data pattern is that both Malo/muy malo series have risen over the past year, but the cross-country gap has remained in a fairly bounded low-to-mid-20s range rather than exploding. From May 2025 to April 2026, Milei’s bad rating rose by 18.0 points and Sheinbaum’s by 13.6 points. In the latest three monthly pairs, the gap was 23.9 pp in February, 25.7 pp in March, and 23.0 pp in April. That history argues for a sticky low-20s baseline with month-to-month noise of a few points, not for a radical regime shift. (cdn.atlasintel.org)
Context is mixed rather than one-sided. Milei has faced corruption-allegation headlines and Reuters reported a marked drop in public approval in March, which supports further deterioration risk; at the same time, the IMF said policy momentum had strengthened in Argentina’s reform program and Fitch upgraded the sovereign to B-, which should cap the odds of an unchecked blowout in bad ratings. For Sheinbaum, Bloomberg described April as her lowest approval reading so far amid economic concerns, and Mexico’s official preliminary GDP estimate showed a 0.8% quarter-on-quarter contraction in Q1 2026. But Sheinbaum has also responded with a fresh investment push and faster approval mechanisms under Plan México, which could keep her numbers from collapsing further by late July. Netting these forces out, I see a slight widening bias from the longer Milei-vs-Sheinbaum trend, but with a substantial narrowing scenario because Mexico’s economy has softened sharply. (investing.com)
My model starts from the April gap of 23.0 pp and adds only a mild drift toward summer. A simple +0.5 pp/month drift from April to a likely July pair gives a center around 24.5 pp, while my three-scenario mixture averages 23.675 pp. I also account for poll noise: the April report pages list a ±1 pp margin of error for Argentina and ±2 pp for Mexico, implying about 2.24 pp of gap uncertainty even before real opinion movement. I therefore use a mixture centered at 23.5, 29.0, and 17.5 with weights 0.55, 0.25, and 0.20 and standard deviations around 4 pp. That yields a forecast centered in the mid-20s, with most probability mass in the high teens through low 30s. My point forecast is 24 pp. (atlasintel.org)
As of May 11, 2026, the live anchor is the April 2026 pair: AtlasIntel’s Argentina report shows 59.3% Malo/muy malo for Javier Milei and the Mexico report shows 36.3% for Claudia Sheinbaum. Under the resolution rule, that is a gap of 23.0 percentage points, which would round to 23. (cdn.atlasintel.org)
Recent movement argues for a result still in the mid-20s by the time the question resolves. In Argentina, the negative government-evaluation share went 53.1% in February, 57.4% in March, and 59.3% in April; in Mexico it went 29.2%, 31.7%, and 36.3%. Those imply realized gaps of 23.9, 25.7, and 23.0 across the last three published pairs: upward pressure overall, but still clustered in a fairly tight band rather than exploding higher. (cdn.atlasintel.org)
On timing, I think the question is most likely to resolve using a July 2026 pair. AtlasIntel has kept this series coming month after month: the country pages show October 2025 releases on October 24, November 2025 releases on December 2, December 2025 releases on December 18, January 2026 releases on January 22, and the public Latam Pulse page lists February, March, and April 2026 country reports released on February 26, March 26, and April 29-30. That history makes a qualifying July pair before August 12, 2026 much more likely than a fallback all the way to May, while an August pair before the deadline looks unlikely. This is an inference from the publication cadence, not a certainty. (atlasintel.org)
Argentina-specific fundamentals are mixed, which keeps me from pushing the Milei number far above the low 60s. Reuters reported in late March that corruption allegations were denting Milei’s popularity, but Reuters also reported on May 5 that Fitch upgraded Argentina to B- and, in a separate Reuters economist poll, that inflation is still expected to cool materially in 2026 even if less than previously hoped. My read is that Milei’s Malo/muy malo number is more likely to keep drifting up than to snap back down, but there is also a plausible stabilization path if macro data improve. (investing.com)
Mexico-specific fundamentals also cut both ways. Bloomberg said on April 30 that Sheinbaum’s approval hit its lowest point so far, and official INEGI releases then showed a 0.8% quarter-on-quarter GDP contraction in Q1 2026 and 4.45% annual inflation in April. At the same time, Reuters reported in February that Sheinbaum launched a 5.6 trillion peso public-private investment plan, which gives her some chance to stabilize sentiment rather than keep deteriorating at April’s pace. That leaves me expecting further softness in Mexico’s numbers, but not a full convergence toward Milei’s far worse Argentine readings. (bloomberg.com)
Putting it together, I center the distribution near 25 pp. My rough country-level expectation for the most likely July-like reading is Milei around 61-62% Malo/muy malo and Sheinbaum around 36-37%, with a broad 90% interval for the final rounded gap of roughly 17-33. The main smaller-gap scenario is that Mexico’s economic slowdown pushes Sheinbaum’s negatives up faster than Milei’s; the main larger-gap scenario is that Milei’s scandals and governing strain keep worsening while Sheinbaum stabilizes. That is why my probability mass is concentrated in the mid-20s, especially 25-27, but with meaningful tails into the high teens and low 30s. (cdn.atlasintel.org)
As of Monday, May 11, 2026, the latest official AtlasIntel Latam Pulse pair is April 2026: Argentina was published on April 29 and Mexico on April 30. In the government-evaluation question, Milei’s Malo/muy malo was 59.3% and Sheinbaum’s was 36.3%, so the current raw gap is 23.0 percentage points, which would round to 23. (atlasintel.org)
Recent momentum has been upward on both sides. From January through April 2026, Milei’s Malo/muy malo moved 47.6 -> 53.1 -> 57.4 -> 59.3, while Sheinbaum’s moved 27.3 -> 29.2 -> 31.7 -> 36.3. That implies raw gaps of 20.3, 23.9, 25.7, and 23.0. Reading the AtlasIntel time-series charts more broadly, the bilateral gap has usually lived in the teens-to-mid-20s rather than near zero or near 40. (cdn.atlasintel.org)
On timing, AtlasIntel has been publishing Latam Pulse monthly and near month-end: July 31 and August 28 in 2025, then February 26, March 26, and April 29-30 in 2026. That makes July 2026 the overwhelmingly most likely latest qualifying pair before the August 12, 2026 deadline; June is the main backup if July is delayed or unverifiable. Because the output schema has no annulment bin, the code is conditional on a numeric resolution; I think annulment risk is very low. (atlasintel.org)
Argentina still looks like the worse of the two tracks. Official INDEC data show March 2026 CPI at 3.4% m/m, while February 2026 EMAE fell 2.1% y/y and 2.6% m/m seasonally adjusted; Reuters and AP also describe corruption allegations and political/press controversies as additional headwinds for Milei. My inference is that this makes a fast improvement in Milei’s Malo/muy malo share by early Q3 2026 unlikely. (indec.gob.ar)
Mexico also has meaningful headwinds, which is why I do not forecast a huge widening of the gap. INEGI’s advance GDP estimate showed Q1 2026 GDP down 0.8% q/q, and official April CPI was 4.45% y/y; Reuters also reports that cartel-related charges involving Sinaloa politicians are creating a split inside Morena. My inference is that Sheinbaum’s Malo/muy malo can keep rising from the April 36.3 reading, even though her standing remains much stronger than Milei’s. (inegi.org.mx)
Putting this together, my base case is a July 2026 raw gap in the mid-20s: a bit above the current 23.0, but not dramatically so, because both leaders’ negative evaluations have been worsening. I center the forecast near 24.7 raw points, which rounds to 25, and I spread uncertainty so that low-20s through high-20s carry most of the mass, with smaller tails into the mid-teens and low-30s. The code implements this as a normal-mixture over May/June/July latest-pair scenarios. (atlasintel.org)
