Mark Kelly (D) defeated incumbent Martha McSally and 17 write-in candidates in the special election for U.S. Senate in Arizona. Kelly will fill the rest of the late-Sen. John McCain’s (R) term. The seat will be up for election in 2022.
In the 2018 general election, McSally ran for Arizona’s other Senate seat, losing to Kyrsten Sinema (D) 47.6% to 50.0%. After the election, interim Sen. Jon Kyl (R) announced his resignation and Gov. Doug Ducey (R) announced McSally as Kyl’s replacement in December 2018.
Before the election, Republicans had a 53-47 majority in the Senate. As of noon ET on November 6, two other seats besides Arizona’s had changed party hands. Tommy Tuberville (R) beat incumbent Doug Jones (D) in Alabama, and John Hickenlooper (D) beat incumbent Cory Gardner (R) in Colorado. Five races remain uncalled.
