The 2024 Missouri Senate election will take place on Tuesday, November 5, 2024, with the primary election to be held on Tuesday, August 6, 2024.[1] [2] Missouri voters will select state senators in the 17 odd-numbered districts of the Senate to serve four-year terms.[3]
The election will coincide with United States national elections and Missouri state elections, including U.S. President, U.S. Senate, U.S. House, Governor, and Missouri House.[4]
Following the previous election in 2022, Republicans held a 24-to-10-seat supermajority over Democrats.[5] Going into the 2024 elections, there are four vacancies after Senator Greg Razer (D) of District 7 resigned on April 25, 2024, Senators Karla Eslinger (R) of District 33 and John Rizzo (D) of District 11 resigned in June 2024, and Lauren Arthur (D) of District 17 resigned in July 2024. Therefore, there are 23 Republicans and seven Democrats at the time of the 2024 election (plus the three vacancies). Democrats would have to net 11 seats to flip control of the chamber.[1]
These will be the first elections in the odd-numbered Missouri Senate districts following the 2020 United States redistricting cycle, which resulted in redrawn legislative district boundaries.[6] [7]
Members of the Missouri General Assembly are prohibited from serving more than eight years in the state senate, due to statutory term limits.[9]
District 7: Greg Razer resigned due to appointment to State Tax Commission.[10]
District 11: John Rizzo resigned to take a position as executive director of the Jackson County Sports Authority.[11]
District 17: Lauren Arthur resigned after being appointed to the Missouri Labor and Industrial Relations Commission.[12] [13]
District 3: Elaine Gannon will retire.[14]
District 15: Andrew Koenig will retire due to term limits (running for State Treasurer).[15]
District 19: Caleb Rowden will retire due to term limits.[16]
District 21: Denny Hoskins will retire due to term limits (running for Secretary of State).[17]
District 23: Bill Eigel will retire due to term limits (running for Governor).[18]
District 27: Holly Thompson Rehder will retire to run for Lieutenant Governor.[19]
