A forecast is labelled speculation. Everything else in this atlas records what happened; this page estimates what might. The ranges are wide because they should be — polls taken months or years before an election have missed by six points and more, and every number below carries that history. When the ranges look absurdly wide, they are working correctly.

United States — the 2026 midterms

3 November 2026, 3 months away. Democrats lead the generic congressional ballot by +6.2 across the major aggregators — and the president's party has lost House seats in almost every midterm since the Civil War.

The House 435 seats · 218 to control

Democrats226 (205249)House 74.8%
Republicans209 (186230)House 25.2%

Median and 90% range of 20,000 simulations. Democrats take the House in 74.8% of them — a lead, not a lock: the generic ballot at this range still misses by ±2.7 points.

Individual-poll feeds thinned after FiveThirtyEight closed in 2025; the aggregators above are averaged as the national input.

The Senate 35 seats up · Democrats need 51, Republicans 50 with the Vice President

Democratic caucus50 (4653)control 35.1%
Republicans50 (4754)control 64.9%

From today's 5347: 22 Republican and 13 Democratic seats are on the ballot. The map, not the national mood, is the obstacle — Democrats can win the night and still miss the majority.

The Governors 36 of 50 mansions on the ballot · 26 for a majority

Democratic governors24 (2128)majority 30.1%
Republican governors26 (2229)majority 52.8%

From today's 2624: 18 Republican and 18 Democratic mansions are on the ballot; the other 14carry over. Governorships are independent state offices, so "majority" means most of the fifty, not control of anything — and the two figures fall short of 100% by the odds of an exact 25–25 split.

United Kingdom — the next general election

Due by August 2029 (modelled as 2029-05), 33 months away. Average of the latest poll from each of 14 pollsters, recency-weighted; latest poll 2026-07-31.

The polling average today

Labour 23.7%Reform UK 23.6%Conservative 20.1%Liberal Democrat 11.6%Green 11.4%SNP 3.1%

Five parties within thirteen points of the lead — the most fragmented polling picture in modern British history, in a system built for two parties.

What the simulations say

Across 4,000 simulated elections: a hung parliament 56.9% of the time · Reform UK largest 41% · Labour largest 33.6% · Conservative largest 24.9% · Reform UK majority 18.3% · Labour majority 17%.

326 seats for a majority. Northern Ireland's 18 seats are held at their 2024 outcome.

Proportional swing from the 2024 result in each of Great Britain's 632 constituencies, with national and per-seat error drawn from the historical record. First past the post makes seat counts hypersensitive: a two-point national move can swing a hundred seats, which is why the bars overlap so heavily.

Brazil — the 2026 presidential election

First round 4 October 2026, 2 months away. Recency-weighted average of 17 first-round polls from the last 45 days; latest 2026-07-29.

First round vote share, %

Lula41.2
F. Bolsonaro33.2
Caiado4.9
Santos4.6
Zema3.0
Cury1.7

Nobody near the 50% needed to win outright, so the numbers point firmly to a runoff.

The runoff 25 October 2026

Lula vs F. Bolsonaro4742Lula 86%

Head-to-head averages simulated with the historical error of Brazilian polls at this horizon — an 8-point first-round lead is far from safe once the field consolidates.

Israel — the 2026 Knesset election

Modelled for 2026-10 on the regular four-year schedule. Israeli pollsters publish seat projections directly; this is the recency-weighted average of 6 published seat polls (a thin base — the cycle's polling has only just begun), renormalised to the Knesset's 120 seats.

Seat averages 120 seats · 61 for a majority

Blue & White2.0

Parties polling under the 3.25% threshold (about four seats) are shown at zero, as the pollsters publish them.

The coalition question

The polls' own tally of the current government bloc averages 49 of 120 seats — reaching 61 in 0% of simulations at today's numbers.

Israeli coalition arithmetic is notoriously fluid: new parties, mergers and surplus-vote agreements routinely move the bloc totals by more than the polling error. The bloc figure is the pollsters' own classification, not ours.

New Zealand — the 2026 general election

Due late 2026 (modelled as 2026-10), 2.5 months away. Latest poll from each of 7 pollsters, recency-weighted; latest 2026-07-19. Seats via Sainte-Laguë with the 5% threshold (electorate-seat waiver assumed for ACT and Te Pāti Māori).

The polling average today

Labour 32.2%National 30.1%NZ First 11.4%Green 10.4%ACT 7.4%TOP 4.6%Te Pāti Māori 2.8%

MMP makes the blocs the real contest: National + ACT + NZ First against Labour + Greens + Te Pāti Māori, with TOP hovering at the threshold.

What the simulations say

Across 10,000 simulated elections: the governing right bloc holds its majority 55.4% of the time · the left bloc takes one 10.7% · neither reaches 61 in 34% — a genuine three-way coin flip.

120 seats, 61 for a majority. Overhang seats and electorate-level upsets are not modelled — they have decided NZ coalitions before.

France — the 2027 presidential election

Due spring 2027 (modelled as 2027-04), 8.2 months away. The heaviest caveat on this page: no candidate has been formally nominated, so pollsters test hypothetical fields. These are scenario averages, not a forecast of a settled race.

First round scenario average, %

Marine Le Pen35.6
Édouard Philippe16.4
Jean-Luc Mélenchon15.0
Raphaël Glucksmann10.5
Gabriel Attal9.4

Marine Tondelier3.6
Éric Zemmour3.3
Dominique de Villepin2.5

5 scenario polls; latest 2026-07-10. The top two advance to the runoff — and second place is wide open.

Nine months out in 2016, the eventual runoff pairing wasn't being polled at all. Treat these as today's temperature, nothing more.

How these forecasts work

The averages

Each pollster's latest poll within 45 days, weighted by recency (14-day half-life) and sample size. A simple transparent average — validated on 22 past elections across four countries, where it called 87% of winners within 1.3 points.

Seats from votes

US House: the generic-ballot margin mapped through the 2012–2024 seats-votes relationship. US Senate and governors: the ratings agencies' consensus per race, converted to win probabilities and simulated with a shared national swing — the governors aggregated to mansions held out of 50, starting from today's 26–24 Republican edge. UK: each party's national movement applied proportionally to its 2024 result in all 632 GB constituencies (Commons Library data). New Zealand: Sainte-Laguë over the simulated party vote. Israel: the pollsters' own seat projections, averaged. Brazil and France: round-by-round candidate averages.

Why the ranges are wide

Polls this far from polling day are weather, not prophecy: three years out, national surveys have missed final results by six points and more (FiveThirtyEight's raw-polls archive; Jennings & Wlezien). The error scales into every simulation, which is why the honest answer is a range.
