The polls tell a clear national story: Democrats have the advantage heading into Tuesday’s midterms. They don’t tell an equally clear story about who will control Congress.
The latest national polling averages put Democrats roughly eight points ahead on the generic congressional ballot—the question of which party voters prefer for Congress, without naming candidates. A final Ipsos poll found Democrats ahead by eight among likely voters, while a YouGov poll put the lead at nine. President Trump’s approval ratings are also poor: in the latest Ipsos figures, more voters disapproved than approved of his performance by a wide margin. These measures describe the national mood, but they cannot account for turnout, candidate quality or the political character of each state and district.

That distinction matters especially in the Senate. Republicans hold 53 seats to Democrats’ 47, and Democrats need a net gain of four to take control. Several Republican-held seats are now competitive, including some in states Trump won comfortably two years ago. But Democrats must also defend their own seats, and a close poll is not a forecast of a win. CBS News’ race guide A national mood shaped by costs and the White House The campaign’s closing argument has largely been about the economy and the cost of living. Democrats have tried to make Trump’s record, including the effects of the Iran war and higher prices, central to the vote. Republicans have argued that Democrats’ agenda is too extreme and pointed to the administration’s policies on issues including taxes on tips and overtime.
The economic message appears to be a particular problem for the president. A recent AP-NORC poll found that just 17% of U.S. adults approved of Trump’s handling of the cost of living, and 26% approved of his handling of the economy overall. Those are national figures, not predictions for individual races, but they help explain why Democrats have been competitive in states where Republicans might ordinarily expect an easier contest.

The president’s standing is a useful guide to the broader political climate, but an imperfect one. Midterms often become a referendum on the party in power, and candidates can benefit from national dissatisfaction. Yet local candidates still have to persuade voters that they fit their state or district. That may help explain why some Democrats are running ahead of the national party’s standing while others face difficult contests even in a favourable climate. The Senate: a path for Democrats, with little room for error The clearest opportunity for Democrats is to turn a favourable national environment into wins in multiple Republican-held seats. The closest contests illustrate both the opportunity and the uncertainty.
In Texas, Democrat James Talarico is challenging Republican Ken Paxton. Paxton’s win over incumbent John Cornyn in the Republican primary left Democrats arguing that his controversies and more conservative profile make him more vulnerable. The polling has attracted national attention: the final New York Times/Siena surveys showed Talarico ahead by seven points. But that result is not a settled consensus. Other polling averages have placed the race closer or shown Paxton ahead. Texas is a major prize for Democrats, but it remains a state Republicans believe they can hold.

In North Carolina, former Democratic governor Roy Cooper is running against Republican Michael Whatley for an open seat. Cooper’s statewide record gives Democrats a strong candidate in a state where they see a realistic route to a gain. In Maine, Republican Susan Collins faces Democrat Troy Jackson. Collins has survived tough reelection races before, but the state’s Democratic lean and Jackson’s late-campaign polling make her seat a serious target.
Ohio is another test of whether candidate reputation can overcome the state’s recent Republican shift. Republican Jon Husted faces former senator Sherrod Brown, whose appeal among working-class voters is central to the Democratic case. In Kansas, Republican Roger Marshall is defending his seat against Adam Hamilton. A Democratic win there would be a historic upset; the race is close enough that national Republicans have spent heavily to protect the seat.
Democrats also have chances in Alaska, where former representative Mary Peltola is challenging Republican Dan Sullivan, and Iowa, where Democrat Josh Turek faces Republican Ashley Hinson. Both states voted for Trump in 2024. Their competitiveness suggests that the anti-incumbent mood may be reaching beyond the states Democrats would normally expect to contest—but polls close to Election Day can still miss who will actually turn out.
The party’s defence matters, too. In Michigan, Democrat Abdul El-Sayed faces Republican Mike Rogers in a race that has been complicated by a divisive primary and a late endorsement of Rogers by former Democratic opponent Haley Stevens. In Georgia, Republican Mike Collins is challenging Democratic senator Jon Ossoff. A strong national Democratic year could help Ossoff, but he is defending a seat in a state where Republicans remain competitive.
That is why the Senate race is harder to call than the generic ballot. A large Democratic lead nationally can coexist with a tight Senate map: votes are distributed across states, and winning the popular vote does not guarantee winning the seats needed for a majority. The final Times/Siena polls showed Democratic leads in all seven Senate battleground states they surveyed, but several of those leads—Maine, Kansas, Ohio, Alaska and Iowa—were within the polls’ margins of error. Axios’ analysis of the final polls and forecasts The House: a more favourable map for Democrats The House is the likelier chamber for Democrats to flip. All 435 seats are up, and Republicans begin with a narrow majority. That gives Democrats more ways to reach the 218 seats needed for control: they need to win a collection of competitive districts rather than prevail in a single statewide contest.
The races to watch include districts in California, Iowa, Michigan, Florida and Virginia. In California’s 22nd District, Republican David Valadao is defending a newly redrawn seat against Democrat Randy Villegas. Iowa’s 1st District has been close in recent elections, and Democrat Christina Bohannan is trying again to defeat Republican Mariannette Miller-Meeks. In Virginia’s 1st District, Republican Rob Wittman faces prosecutor Shannon Taylor in what AP describes as the toughest reelection contest of his long congressional career.

Redistricting adds another layer. Some incumbents are defending altered districts, and open seats can be more competitive than seats held by familiar representatives. In these races, a national swing may decide the direction of the contest without determining its size. A few close outcomes could give Democrats the House; a stronger-than-expected Republican turnout could preserve the GOP majority despite Democrats’ lead in the national vote. Polling has a warning label The Democratic lead is substantial enough to establish a clear direction, but it should not be mistaken for certainty about the scale—or even the final outcome—of every race. National averages combine polls with different methods and samples. Likely-voter screens attempt to model who will vote, but turnout in a midterm is especially hard to predict. And polls in one state may not capture the same electorate as polls in another.
There are also reasons to be cautious about confident predictions. The New York Times’ polling chief has warned that white Democrats were more likely than white Republicans to respond to the paper’s final surveys, a possible source of bias. The Washington Post raised a similar concern after finding an unusually large participation gap between Democrats and Republicans in its Kansas poll. Those observations do not prove the polls are wrong; they are reasons to treat narrow leads with care. Axios’ polling review
Early voting is up compared with 2022: AP reported more than 57 million ballots cast across 47 states and Washington, D.C., as of Monday, versus just under 44.5 million across 49 states and Washington, D.C., at the same point in 2022. That is a striking increase, but it does not by itself show which party is advantaged. Early voting is not a representative sample of all Election Day voters, and participation patterns vary by state. AP’s election-eve report What to watch Tuesday The first broad signal will be whether Democrats translate their national advantage into gains across House districts. If they do, the House could change hands even if several Senate battlegrounds remain close. In the Senate, the key question is whether Democrats can win more than one of the Republican-held contests in states such as North Carolina, Maine, Ohio, Texas, Kansas and Alaska while holding their own vulnerable seats.
A Democratic wave is the clearest reading of the final national polls. A Democratic Senate majority is a narrower proposition: it depends on several state-level results landing together. And if polls have overstated Democratic support, contests currently described as toss-ups may break toward Republicans.
For now, the fairest assessment is that Democrats enter Election Day favoured to make House gains and have a real, if difficult, path to the Senate. The national environment gives them the opening. The candidates, turnout and state-by-state margins will determine whether they can use it.
