Emerson poll: Democrats lead GOP 52% to 42% for Congress four days before midterms

Democrats lead Republicans by 10 points on the generic congressional ballot four days before the midterm election, according to a new Emerson College Polling survey released Friday. The poll found 52 percent of likely voters backing Democrats and 42 percent backing Republicans ¹². A generic ballot asks voters which party they want in control of Congress, without naming candidates.

The lead is only slightly smaller than the 11 points Democrats held in Emerson's September survey ¹. About 5 percent of voters are still undecided ¹².

A steady trend

Emerson began tracking this election cycle in July 2025. Republican support is ending at the same 42 percent where it started, while Democratic support has risen from 44 percent to 52 percent ¹².

Emerson's executive director, Spencer Kimball, said Democratic support climbed eight points over the past fifteen months, from 44% to 52%, with undecided and swing voters clearly shifting in the Democrats' favor ¹.

Emerson's executive director, Spencer Kimball, said most of the undecided voters are independents, and half of them disapprove of Trump ¹². He said that means Democrats' ceiling "could be higher than the poll reports" ¹.

Trump's standing

In the poll, 37 percent of likely voters approve of Trump's job performance and 57 percent disapprove. The disapproval figure is up 6 points since January ¹. The Hill reported that his ratings have fallen amid the administration's military operations against Iran and a trade fight with Canada ¹.

Emerson found cost of living was the top issue, named by 34 percent of voters. Fighting corruption in government was next at 28 percent ².

Who is more eager to vote

The poll also shows an enthusiasm gap. The Hill reported that 92 percent of Democrats said they were very or somewhat excited to vote, compared with 85 percent of Republicans ¹. Emerson's release says 76 percent of Democrats are "very excited," compared with 64 percent of Republicans and 62 percent of independents ².

The survey was conducted Oct. 24-26 among 1,000 likely voters. Its margin of error is about 3 percentage points ¹².

What happens next

Decision Desk HQ's forecast on Thursday put Democrats' chances of winning the House at 80 percent. It put their chances of winning the Senate at 60 percent ¹. Polls come with error margins, and a national lead does not decide individual districts or Senate races.

Still, this is one more high-quality poll pointing the same way. For voters who have been told the House is out of reach for Democrats, the numbers say it is not. Polls close Tuesday, Nov. 3, and the outcome depends on who turns out.
