Ex-Pinal County Sheriff Mark Lamb Runs for Arizona's 5th Congressional District Seat

Former Pinal County Sheriff Mark Lamb has officially announced his candidacy for the Republican primary in Arizona's heavily conservative 5th Congressional District, which includes parts of Gilbert, Queen Creek, Chandler, and Mesa. He aims to replace U.S. Rep. Andy Biggs, who is vacating the seat to run for governor. Lamb, who served eight years as sheriff and previously ran unsuccessfully for U.S. Senate in 2024, is considered one of the leading contenders in a crowded GOP primary. His campaign has drawn attention due to his associations with the constitutional sheriff movement, a group known for its anti-government views and ties to conspiracy theories. Lamb's opponents in the primary include former state lawmaker Travis Grantham and former NFL kicker Jay Feely. Despite some controversy, Lamb's law enforcement background and political connections position him as a strong candidate in this ruby red district.
