The 2024 United States Senate election in Arizona will be held on November 5, 2024, to elect a member of the United States Senate to represent the state of Arizona. Democratic congressman Ruben Gallego and Republican former news anchor Kari Lake are seeking their first term in office. The winner will succeed independent incumbent Kyrsten Sinema, who is not seeking re-election after one term.[1][2] The election is considered essential for Democrats' chances to retain the Senate majority in 2024.[3]
Primary elections took place on July 30, 2024.[4] Gallego won the Democratic nomination without opposition, while Lake received 55% of the vote against Pinal County sheriff Mark Lamb in the Republican primary. This is Arizona's second statewide election to have Lake as the Republican nominee, following her unsuccessful gubernatorial bid in 2022.
