US midterms: What six leading forecasters predict about 2026 election outcome

Democrats are heading into the midterm elections with growing confidence, as several leading election forecasting organizations point to a potentially strong performance for the party. Predictions released ahead of Election Day suggest Democrats have a significant opportunity to regain control of the House of Representatives and could also make substantial gains in the Senate.

President Donald Trump's declining approval ratings have added to the challenges facing the party in power. Although election forecasts are not guarantees of the final outcome, the latest projections indicate that Democrats have momentum in several closely contested congressional races.

Midterm elections have traditionally been difficult for the party occupying the White House, as voters often use these contests to express dissatisfaction with the administration. This historical pattern has strengthened Democratic expectations of making congressional gains.

Recent polling has also reflected a favorable national environment for Democrats. According to RealClearPolitics, Democrats held an 8.9-percentage-point advantage on the generic congressional ballot as of Monday. This represents a considerable improvement compared with the 2022 midterm cycle, when Republicans enjoyed a 2.5-point advantage in the same polling measure before ultimately winning the national generic ballot by 2.8 points.

However, polling accuracy remains an important consideration. Surveys have occasionally overstated Democratic support, particularly during presidential elections. Nevertheless, polling performed relatively well during recent midterm contests.

Democrats appear to have a relatively clear path toward taking control of the House of Representatives. Before Election Day, Republicans held 218 seats, compared with 214 for Democrats. This narrow difference means Democrats need only a small number of victories to secure a majority.

Redistricting and Republican-friendly electoral maps in several Southern states could make the contest more complicated. However, a substantial Democratic advantage in the national vote could help offset those disadvantages.

Several major forecasting organizations have consequently placed Democrats in a favorable position to capture the chamber. The Senate race is considerably more complicated for Democrats. Republicans currently hold 53 seats, while Democrats control 47.

Democrats would therefore need to gain four seats to reach a majority, with Vice President JD Vance available to break a 50-50 tie. North Carolina and Maine are among the most important opportunities for Democrats. However, the party may also need victories in traditionally Republican-leaning states to achieve its goal.

Here is what six major election forecasters expect. Cook Political Report identifies several closely contested Senate elections, with 11 seats classified as Solid or Likely Democratic and 13 placed in the Solid or Likely Republican categories.

Minnesota and New Hampshire are considered favorable for Democrats, while Nebraska and South Carolina lean toward Republicans.
