The Arizona primary elections on July 30, 2024, saw significant contests and results across various races. Notably, Kari Lake won the Republican nomination for U.S. Senate, while Ruben Gallego ran uncontested for the Democratic nomination. In local elections, incumbents and new challengers competed, with key races in Maricopa County and district legislative seats showing tight margins. Early ballots dropped off on election day remain uncounted, with full unofficial results expected by Monday. High-profile races include the GOP race for Arizona's 8th Congressional District and the Democratic primary for the state's 1st Congressional District, among others. Voter turnout and the impact of these primary results on November's general election are being closely monitored.
