About this race
Arizona's 6th Congressional District race is for a U.S. House seat covering southeastern Arizona, including parts of Tucson, Casa Grande, and Sierra Vista. The district is one of the most competitive in the country, rated a "toss-up" by the Cook Political Report, and its outcome could help decide control of the narrowly divided U.S. House.
Republican incumbent Juan Ciscomani, seeking a third term, faces Democratic nominee JoAnna Mendoza, a retired U.S. Marine who advanced from the July 21, 2026 primary; Libertarian Jereme Peters, Green Party nominee Gary Swing, and independent write-in Michael Dorland are also on the November 3, 2026 ballot. The campaign has centered on the One Big Beautiful Bill Act's effects on SNAP and AHCCCS, healthcare and rural hospitals, affordability, and immigration, with Ciscomani and Mendoza meeting in a Sept. 10 Clean Elections debate and trading attack ads into late September.
