The story so far
written Oct 3What is happening
Control of the U.S. Senate determines the legislative agenda and the confirmation of judicial and executive branch nominees for the final two years of the current presidential term [1]. Republicans currently hold a 53-47 working majority in the chamber [1]. This composition includes 53 Republicans, 45 Democrats, and two independents who caucus with the Democratic party [1].
What to watch
Voters will decide 35 Senate seats in the general election scheduled for November 3, 2026 [1]. The certification of these results by state election officials and the official announcement of the party composition by the Senate Clerk would settle the question of majority control. The resolution of any recounts or contested results by state courts would also determine the final seat count.
The 2026 cycle includes 33 regularly scheduled Class 2 seats and two special elections [1]. These special elections in Ohio and Florida follow the resignations of JD Vance and Marco Rubio [4].

How we got here
Republicans are defending 22 of the seats up for election this year, while Democrats are defending 13 [4]. A party needs 51 seats to secure a majority, or 50 seats if they hold the vice presidency to provide a tie-breaking vote [1]. This election is the first since 2006 in which Senate Republicans are led by John Thune [4].
