November 5 AP-projected Arizona congressional race result, with precise information about the candidates and post-election certification.
Associated Press calls Arizona's 6th District
Democrat JoAnna Mendoza defeated incumbent Republican U.S. Representative Juan Ciscomani in Arizona's 6th Congressional District, according to an Associated Press race call reported on November 5, 2026. The contest had been one of the most closely watched House races in the country. The district includes parts of Tucson and surrounding southern Arizona communities. Mendoza's win changes the seat from Republican to Democratic representation when the next Congress convenes in January 2027.
A closely fought campaign
Mendoza, a former Marine who had not previously held elected office, campaigned on healthcare, everyday prices and support for communities in the district. Ciscomani, who won in 2022 and narrowly again in 2024, emphasized his work with both parties and defended Republican tax and spending policies. The local public-media outlet AZPM reported Mendoza leading with about 53% of votes as AP called the race Thursday. That was an observation from an incomplete count rather than the final certified percentage.
Part of the changing national House
The win adds one seat to the Democratic Party's already projected House majority following the November 3 midterms. Other new pickups span Nevada, New Jersey, Wisconsin and North Carolina, though each reflects its own candidate and geographic circumstances. Formal Arizona election procedures will determine the final certified vote margin.
