2024 United States Senate elections (YoungLibertarian20)

The 2024 United States Senate elections will be held on November 5, 2024, with 33 of the 100 seats in the Senate being contested in regular elections, the winners of which will serve six-year terms in the United States Congress from January 3, 2025, to January 3, 2031. Senators are divided into three groups, or classes, whose terms are staggered so that a different class is elected every two years. Class 1 senators were last elected in 2018, and will be up for election again in 2024. These elections will run concurrent with the 2024 United States presidential election. Democrats have 23 seats up for election, additionally 2 independents who caucused with the Democrats faced the end of their current term. Republicans have 9 seats up for election.

Four Democratic senators announced their retirements, including Dianne Feinstein, Tom Carper, Kirsten Gillibrand and Joe Manchin. An Independent who caucuses with Democrats, Angus King, is also retiring. One Republican, Ted Cruz, also retired in honor of a previous pledge to honor term limits. Democrats are defending three seats in states previously won by Donald Trump in 2020. One of those seats is open for the first time since 2010 due to Manchin's retirement.

Republicans won a supermajority of seats following the election, the first such occurrence for the party since 1920. Their wins were entitled a "Red Tsunami" in which Republicans gained unified control of the presidency, House and Senate for the first time since 2016. Six Democratic incumbents were defeated in the general election including Debbie Stabenow, Jon Tester, Jacky Rosen, Sherrod Brown, and Tammy Baldwin. Democrat Kyrsten Sinema was the lone senator to lose re-nomination but the seat was later gained by Republicans in the general election. Democrat Joe Manchin's open seat was won by Republican Alex Mooney. Independent Angus King consistently caucused with Democrats during his tenure and his seat was later won by Democrat Sara Gideon. The closest Senate race was in Pennsylvania where Bob Casey, Jr. was the only Democratic incumbent to win their Senate race in a state won by Donald Trump in 2024.

Mitch McConnell had announced prior to the election that he would step down from Republican leadership due to increased pressure to do so by Donald Trump. He was later replaced as Senate Majority Leader by Senator John Barrasso of Wyoming.
