Compare candidates’ positions, polling, and sourced race updates.
Arizona's 6th Congressional District race is for a U.S. House seat in southeast Arizona, including parts of Tucson and Casa Grande. The district is widely viewed as competitive and a likely battleground because recent presidential results have been very close. Republican incumbent Juan Ciscomani is seeking a third term, while Democratic challenger JoAnna Mendoza, a retired U.S. Marine, advanced from the July 21, 2026 primary to face him in the general election on November 3, 2026. Libertarian Jereme Peters is also on the ballot, giving voters an incumbent-versus-challenger contrast in a closely divided district.
