What happened

On the eve of the Nov. 3 midterms, final polls, forecasts and betting markets pointed to big Democratic gains. New York Times/Siena polls showed Democrats leading all seven Senate battlegrounds. Pollsters also warned that Democrats were answering surveys at higher rates than Republicans, a gap that could mean the polls overstate Democratic support.

Summary

Heading into Tuesday's midterms, nearly every measure pointed the same way. Final New York Times/Siena polls showed Democrats ahead in all seven Senate battlegrounds: by 11 points in Michigan, 7 in Texas, 6 in Maine, 5 each in Ohio and Kansas, 2 in Alaska and 1 in Iowa. Axios notes that the last five leads fall within the margin of error. The final NBC News poll gave Democrats a 52% to 45% edge on the generic ballot, which asks which party voters want in Congress. Forecaster Nate Silver put Democrats' chances at 95% for the House and 80% for the Senate. [2] [9] [10]

The catch is who picks up the phone. Times polling chief Nate Cohn warned that white Democrats were about 30% more likely than white Republicans to take the final surveys. That gap is slightly wider than in 2020, when polls overstated Democratic support. In Kansas, the Washington Post found registered Democrats were more than twice as likely to finish its survey, 32% versus 12%. Pollsters sometimes call this differential nonresponse. They adjust, or weight, their results to match a state's makeup, but CNN notes that weighting may not fully fix the gap. Times/Siena also found that voters who decided in the last month favored Republicans by 9 points. [6] [7] [9] [10]

Republicans have seized on those doubts. Trump and House Speaker Mike Johnson accused pollsters of manufacturing the look of a Democratic wave to hold down GOP turnout, and a Fox Business commentary argued that Republicans will keep the Senate. Even so, in his election-eve speech Trump acknowledged that historically the president's party "doesn't win the midterms." Final results may take a while. In Alaska, absentee ballots can be counted through Nov. 18, with certification targeted for Nov. 25. A close race there could leave Senate control unsettled into December. [2] [4] [8] [9]

Key questions

Why might the 2026 midterm polls be wrong?

Democrats have been far more willing than Republicans to answer surveys this year, and weighting may not fully correct for that. Some Republicans who skip polls could still turn out to vote. [7] [9]

Who is favored to win the House and Senate in 2026?

Strategists in both parties say Democrats are likely to win the House, and Nate Silver's model gives them a 95% chance there and an 80% chance in the Senate. Some analysts still describe the Senate as more uncertain. [1] [9]

When will we know which party controls the Senate?

If the outcome depends on a close Alaska race, it could take weeks. Counting there can continue through Nov. 18, certification is targeted for Nov. 25, and a recount or court fight could push the answer into December. [2] [4]
