Arizona is already expected to play a critical role in the White House race as it did in 2020, but Tuesday’s state primaries will set the stage for competitive contests that could determine control of the closely divided U.S. Senate, U.S. House and both chambers of the state legislature. Topping the ballot Tuesday is the Republican primary in the race to replace U.S. Sen. Kyrsten Sinema, who was elected as a Democrat in 2018 but became an independent in 2022 after years of bucking her party on key votes. Sinema faced a tough road to reelection after U.S. Rep. Ruben Gallego launched his bid for the Democratic nomination in 2023, raising the specter of a three-way general election in the competitive swing state.
