Key takeaway

Cook now rates Democrats favoured to win a House majority, with a likeliest gain of 12 to 22 seats.

The Cook Political Report, a non-partisan race-rating service, moved 19 House races towards Democrats on 23 October and none towards Republicans⁠¹. Six went from Toss Up to Lean Democrat, four of them held by Republican incumbents, and two open seats moved from Lean Republican to Toss Up. Cook says Democrats are favoured outright in the 218 seats needed for a majority in the House of Representatives, and puts the likeliest result at a Democratic gain of 12 to 22 seats.

Sabato's Crystal Ball, the University of Virginia's forecaster, reached the same line first: 28 House changes on 20 October pushed the seats it rates at least leaning Democratic past 218⁠². The latest batch extends a run of Cook moves in one direction, after it shifted 15 races towards Democrats on 25 September and about 29 more earlier this month.

Ratings are forecasts built on polls, money and history, and no votes have been counted. Republicans hold The House until the new Congress sits in January.

Deep Analysis

In plain English

A party needs 218 seats in The House of Representatives for a majority. Republicans hold it now. Independent forecasters such as The Cook Political Report rate each race as safe, likely, leaning or a toss-up for one party. On 23 October Cook moved 19 races towards Democrats and none towards Republicans. Cook now says Democrats are favoured to win a majority. These are forecasts, not results: no votes have been counted yet.

Deep Analysis

Root Causes

Midterms tend to punish the president's party; one reason is that the out-party's voters are more motivated to turn out when they hold no power in Washington. Since the Second World War the president's party has lost House seats in most midterms.

Rating services also respond to the same inputs, mainly polls and fundraising reports. When those move one way, several raters tend to move together, as Cook and Sabato did within three days.

Source Landscape

This story draws on neutral-leaning sources

Primary parallel: In 2018, the last midterm with Donald Trump in The White House, the main raters moved House seats steadily towards Democrats through October, and Democrats took The House.

Counter-parallel: In 2022 the same raters expected a large Republican gain, and Republicans won The House by a far narrower margin than forecast. One-directional rating moves have overshot before.

Consensus view: The Cook Political Report and Sabato's Crystal Ball now both put Democrats at or past 218 seats at least leaning their way, after Sabato's 28 changes on 20 October and Cook's 19 on 23 October.

Counter-view: No votes have been counted, and Cook had already moved about 29 House races towards Democrats since 1 October. Late moves in the same direction can reflect raters reading the same polls as much as new evidence.

Key tension: Whether the Toss Up seats Cook still lists break together, as in most wave years, or split.

Different Perspectives

Missouri voters

Missouri voters rejected Proposition A by 61.83% to 38.17% at 95% reporting, repealing the 2025 map that split Kansas City. Trump carried the state, yet its 2022 lines now stay for future elections too.

Senate Leadership Fund (SLF)

SLF reported about $43.9m of independent expenditures from 27 October to 1 November, almost all against Democrats, including $12.37m against Sherrod Brown. Seven of its ten targets won; Dan Osborn lost in Nebraska and two are uncalled.

Richard Hudson, chair of the National Republican Congressional Committee

Hudson, who runs House Republicans' campaign arm, conceded North Carolina's 9th District to Richard Ojeda before any AP call. Democrats lead 10 of the state's 14 House districts on the unofficial feed.

Department of Justice (DOJ)

DOJ lost before Judge David O. Carter on 28 October and a 9th Circuit panel on 30 October on its demand to set aside 20,000 California ballots, and says it will appeal the Alaska dismissal. No court has set a ballot aside.

Senator Dan S. Sullivan

Sullivan, who trails Mary Peltola 48.2% to 47.9% on first choices, told CNN he would accept the result. DOJ's suit to stop Alaska certifying anyone but him was dismissed on 1 November.

Scott Colom's campaign

Colom's campaign estimates that about 15,000 affidavit ballots remain to be counted in a race he leads by roughly 65 to 100 votes. Those ballots count only if voters confirm their ID or eligibility by 5pm on 10 November.
