About this election
The 2024 United States Senate elections were held on 5 November 2024, alongside the presidential election. Republicans regained control of the chamber, making a net gain of four seats to finish with 53 against 45 Democrats and two allied independents, an effective 53–47 split. Combined with Donald Trump's presidential victory and the retention of the House, the result handed Republicans unified control of the federal government.
Thirty-four seats were contested — the Class 1 senators, including a regular and a special election in Nebraska. Each seat was decided by statewide vote for a six-year term. The independents Bernie Sanders of Vermont and Angus King of Maine, who caucus with the Democrats, were both re-elected. The map shows the winning party in each state that held a Senate race in 2024.
Democrats were defending 23 of the 34 seats, including several in states Trump was favoured to carry, an exposure that mirrored their difficult 2018 cycle in reverse. The cycle opened with the retirement of Joe Manchin in West Virginia, a seat Republicans were certain to capture, effectively starting the Democrats one seat behind.
Republicans flipped four seats. Governor Jim Justice won the open seat in West Virginia; Bernie Moreno defeated Sherrod Brown in Ohio; Tim Sheehy unseated Jon Tester in Montana; and Dave McCormick narrowly defeated Bob Casey in Pennsylvania after a recount. Democrats, remarkably, held the line everywhere else, with their incumbents and candidates in Arizona, Michigan, Nevada and Wisconsin running ahead of Kamala Harris and winning even as Trump carried those states at the presidential level — a striking degree of ticket-splitting in an otherwise nationalised era.
The new Republican majority restored the party's control of confirmations and committee agendas after four years out of power, smoothing the path for the incoming Trump administration's nominees and judicial appointments. The persistence of split-ticket results in the battleground states, however, underscored that even amid a Republican sweep a number of Democratic senators retained a personal hold on voters their presidential ticket could not match.
