The midterms, measured — and modeled

Published polls and forecaster ratings first, each dated and linked to its source. Then Pheme's synthetic public answering the same questions, set beside the polls so the gap shows. Pheme does not forecast seats or call races, and its modeled answers are a simulation, not a poll.

Election day is Tuesday, Nov. 3, 2026.

Observed snapshot as of Oct. 8, 2026

What is on the ballot

Senate

53 R · 47 D

35 seats are on the ballot. Democrats (the 47 include two independents who caucus with them) need a net gain of four seats for a majority, because the vice president breaks a 50–50 tie.

House

All 435 seats

218 seats make a majority. Republicans hold a narrow majority going in; the exact count moves with vacancies and special elections, so check the Press Gallery tally rather than a number copied here.

Maps

Redrawn mid-decade

Several states redrew their House maps before 2026, including Texas and California, where voters approved Proposition 50 in November 2025. Comparing a district to its 2024 result can mislead where the lines moved.

The House vote, as polled

The generic ballot asks which party's candidate you would back in your own district. It does not name candidates, and it is a national number: it cannot say which seats change hands.

Trump’s effect on the vote

A midterm is usually read as a verdict on the sitting president. These are the published measures of how much this one is about Donald Trump.

Vote is against him
44% versus 19% who call their House vote a vote for him. In October 2022 the same question about Biden read 36% against, 19% for. Pew Research Center ↗ · Oct. 4, 2026
“Extremely motivated” to vote
63% vs 46% Democratic-candidate supporters versus Republican-candidate supporters. Pew Research Center ↗ · Oct. 4, 2026

The modeled public, beside the polls

Every day Pheme puts these questions to its synthetic population: Census-weighted personas, reasoned by a language model. Nobody is surveyed. The Gap column is modeled minus observed. A large gap is the model missing, and it is shown on purpose.

House vote

“If the 2026 election for the U.S. House were held today, would you vote for the Democratic or the Republican candidate in your district?”

Modeled Loading the latest daily run…

AnswerModeledObservedGap
Democrat—44%—
Republican—36%—
Undecided———

Bias-corrected reading: shown once a run carries one.

Observed column: Pew, registered voters, Sept. 28 – Oct. 4. Pew also offered “another candidate” (5%) and left 15% not sure, so compare the Democratic-minus-Republican margin rather than each party's level.

Trump job approval

“Do you approve or disapprove of the way Donald Trump is handling his job as president?”

Modeled Loading the latest daily run…

AnswerModeledObservedGap
Approve—30%—
Disapprove———
Unsure———

Observed column: Pew, Sept. 28 – Oct. 4. Pew reports approval only in this release; the modeled Disapprove and Unsure have no published counterpart here.

Is the House vote about Trump?

“Will your vote for Congress this November be a vote to support Donald Trump, a vote to oppose him, or is he not a factor?”

Modeled Loading the latest daily run…

AnswerModeledObservedGap
Support Trump—19%—
Oppose Trump—44%—
Not a factor———

Observed column: Pew, Sept. 28 – Oct. 4. The remaining Pew respondents said Trump is not a factor or gave no answer; that residual is not published as one number.

Top issue

“Which issue matters most to your vote for Congress this year?”

Cost of living—
Gas and energy prices—
Health care—

No directly comparable published question: Pew asks how important each issue is, not which one matters most.
