Democrats Favored to Seize 52-48 Majority as GOP Faces Losses in Three States

Democrats are now favored to take control of the U.S. Senate in Tuesday’s midterm elections, with a new forecast from Decision Desk HQ giving the party a 64% probability of winning the majority and projecting a 52-48 Democratic advantage in the next Congress.

The latest election model points to three Republican-held seats as particularly vulnerable: Texas, Alaska, and Maine. Democratic victories in those states could produce a dramatic shift in Washington, where Republicans are fighting to maintain their Senate majority amid a difficult political environment.

In Texas, Decision Desk HQ estimates that Democrat James Talarico has a 61% likelihood of defeating Republican Attorney General Ken Paxton. The contest has attracted national attention because Texas has long been a Republican stronghold, making a Democratic victory there a potentially significant setback for the GOP.

Alaska presents another possible Democratic pickup, with former Democratic Rep. Mary Peltola assigned a 61% chance of defeating incumbent Republican Sen. Dan Sullivan. Peltola’s previous statewide electoral success has made her a formidable challenger in a state that generally favors Republicans in federal elections.

In Maine, former state Senate President Troy Jackson is given a 63% probability of unseating Republican Sen. Susan Collins, whose long tenure and reputation for political independence have helped her survive previous Democratic challenges.

The same forecasting model gives Republicans a 36% chance of retaining Senate control, leaving open the possibility that the GOP could outperform current expectations in several closely contested states.

The projections mark a substantial change from the political landscape a year earlier, when Republicans appeared well positioned to defend their majority. At the time, Democrats faced the difficult task of capturing Senate seats in multiple states that President Trump had carried by comfortable margins during the 2024 presidential election.

Republican prospects have since been complicated by declining approval ratings for President Trump, persistent voter frustration over household expenses, and economic concerns tied to tariffs and higher prices associated with the Iran war.

Despite the improving Democratic outlook, Decision Desk HQ chief elections analyst Geoffrey Skelley warned that early voting figures should not be interpreted as reliable predictions of the final results, particularly because Republicans have increasingly concentrated their participation on Election Day.

“Friends don’t let friends read too much into absentee and early voting data,” Skelley wrote in an analysis of voting patterns ahead of Tuesday’s elections.

Texas provides one example of the uncertainty. Through October 31, voters classified as Republicans by a statistical model accounted for approximately 42% of early ballots, compared with 39% identified as Democrats. Although that represents a smaller Republican advantage than in 2024, Skelley cautioned that a strong Election Day showing by GOP voters could still deliver a victory for Paxton.

Skelley also pointed to early voting trends in Kansas and Iowa, where Democrats have improved their position compared with previous elections. Both states have traditionally leaned Republican, however, and stronger Democratic participation before Election Day does not necessarily mean the party will overcome the GOP’s historical advantage.

The stakes are particularly high because Republicans entered the election cycle holding 53 Senate seats, compared with 47 held by Democrats and independents who caucus with them. Democrats therefore need a net gain of four seats to secure outright control. A 50-50 split would leave Republicans in charge because Vice President JD Vance would retain the power to cast tie-breaking votes.

Decision Desk HQ’s forecasting system runs one million simulations using polling, historical voting patterns, and other electoral data. While its latest projections favor Democrats, the relatively narrow probabilities in several battleground states mean that even modest changes in voter turnout could produce a substantially different Senate map when the votes are counted Tuesday night.
