How many Democrats, Republicans are in the Senate? Current makeup before election.

The 2024 presidential election may be taking up most of the political limelight as we approach November, but 33 senators and every member of the House of Representatives is also up for re-election.

Democrats currently hold a narrow majority in the Senate. Many voters are closely watching Senate seats that could flip, like that of Sen. Joe Manchin, a centrist Democrat from West Virginia who will not seek re-election. Independent Sen. Kyrsten Sinema is being challenged by Republican Kari Lake and Democratic Rep. Ruben Gallego.

Three independents serve in the Senate in 2023; all three of their seats are up for re-election in 2024. Vermont Senator Bernie Sanders is the longest-serving independent member of Congress in U.S. history. Angus King, the senator from Maine, is the state’s first independent Senator and has served since 2013.

Sen. Kyrsten Sinema from Arizona left the Democratic party in December 2022, citing “political extremes” and a “broken partisan system.” Sinema’s decision did not change the Democratic majority, and Majority Leader Schumer confirmed she would maintain her committee assignments.

After her departure, Sinema said she planned to caucus with Democrats but remain uninvolved in party leadership votes and advancing broader Democratic efforts.
