The story so far
written Oct 7What is happening
Control of the U.S. Senate and the ability to confirm judicial nominees or pass federal legislation depend on the outcome of 35 seats contested in the November 3, 2026, midterm elections [4][5]. Democrats require a net gain of four seats to take the majority from Republicans, who currently hold 53 seats to the Democratic conference's 47 [4][6]. The election includes 33 regular contests and two special elections in Ohio and Florida following the resignations of JD Vance and Marco Rubio [4][5].
Early voting began in Ohio on October 7 [1]. Republican candidates are defending a stronghold in Texas, where Donald Trump made his third visit in a month on October 7 [1]. Modeling by The Economist indicates a slight 0.1 percentage point increase in the probability of Republicans retaining the chamber, while an ActiVote survey showed the Democratic lead in a generic-ballot poll narrowing to five points [8].
What to watch
Voters will cast ballots in 35 Senate races on November 3, 2026 [4]. The Federal Election Commission will publish final certified vote totals for each race following the conclusion of state-level tallies. Official election results will certify the party composition of the chamber.
Court rulings or recounts would resolve any contested results in individual states. The Senate will convene at the start of the new Congress to confirm the majority party and seat the winners of the 2026 cycle.

How we got here
The current Senate consists of 53 Republicans, 45 Democrats, and two independents who caucus with the Democrats [4][5]. John Thune leads the Senate Republicans, marking the first election cycle since 2006 that the conference has not been led by Mitch McConnell [4]. Chuck Schumer continues to lead the Democratic conference [4].
Primary elections to determine the candidates for these seats have already concluded in states including Delaware, Florida, and Massachusetts [14][15][16]. The 2026 cycle features a high number of Republican-held seats in the Class 2 group, which are contested every six years [4].

Democrats require a net gain of four seats to seize control of the U.S. Senate in the upcoming November 3, 2026, midterm elections [4][6]. The current chamber consists of 53 Republicans, 45 Democrats, and two independents [4][5]. A total of 35 seats are up for election, including 33 regular Class 2 contests and special elections in Ohio and Florida following the resignations of JD Vance and Marco Rubio [4][5].
Recent polling indicates Democrats are attracting significant portions of Republican voters in key races [3]. However, an ActiVote generic-ballot survey showed the Democratic lead narrowing to five points, down from a previous eight-point average [8]. Republican candidates are currently defending a longtime stronghold in Texas, where Donald Trump made his third visit in a month on October 7 [1]. In Ohio, early voting began on October 7 with voters appearing at polling sites before dawn [1].
Senate Republicans are led by John Thune, marking the first election cycle since 2006 without Mitch McConnell at the helm of the conference [4]. The Democratic conference continues under the leadership of Chuck Schumer [4]. While the Senate remains "up for grabs," recent modeling by The Economist suggests a slight 0.1 percentage point increase in the probability of Republicans retaining the chamber [3][8].
