U.S. Senate Seats up for Reelection
[This article was updated on JSeptember 2, 2025]
Republicans won the Senate in 2025, giving them control for at least the next two years and creating a path for President-elect Donald Trump’s priorities.Of the current 100 Senators, 53 are Republicans, 45 are Democrats, and 2 are Independents. Republicans successfully defended all their own seats for the first time since 2014.
But it's never too early for reelection vision time. The time to start organizing is now.
There are 535 Members of Congress, 100 of whom serve in the U.S. Senate and 435 of whom serve in the U.S. House of Representatives.
Each state sends two Senators to represent it in the U.S. Senate. The majority has the power to schedule when various bills come to the floor for voting, but a single Senator can slow legislation from coming to the floor for a vote.
Since debate in the Senate is not concluded until 60 Senators vote for a cloture motion to approve a bill for consideration, the majority must also coordinate with the minority party to set the rules for debate on legislation.
Under this system, legislation can be debated for one or two weeks on the Senate floor alone.
Senators serve a six-year term, and elections to the Senate are staggered over even years, so approximately one-third of the Senate is up for reelection during any election.
