Voters in Arizona's 6th Congressional District will choose between Republican incumbent Juan Ciscomani and Democrat JoAnna Mendoza on November 3, 2026. Unofficial results are expected that evening, with final confirmation in close races possibly taking several days or weeks.
Why it matters
The district's outcome will factor into which party controls the U.S. House, and the race has drawn substantial outside spending. Its results will show how voters in Pima and Cochise counties weigh the candidates' records and campaign messaging.
Total spending on the race exceeded $25 million as of mid-October 2026, with each major House super PAC at about $5 million and Tomorrow Together contributing roughly $1 million for Mendoza. The final tally will not be known until ballots are counted, and close races may take days or weeks to certify.
The players
Juan Ciscomani
Juan Ciscomani is the Republican incumbent seeking reelection in Arizona's 6th Congressional District, which covers Pima and Cochise counties.
JoAnna Mendoza
JoAnna Mendoza is the Democratic candidate challenging Ciscomani in Arizona's 6th Congressional District in the 2026 election.
The details
Early voting in the district began October 7, 2026, ahead of the November 3 election. Mendoza's campaign ran an August TV ad calling Ciscomani 'spineless,' while Republican ads pointed to a property tax filing error that saved Mendoza about $400 per year since 2024.
Timeline
2024: Ciscomani defeated Democrat Kirsten Engel by several points.
August 2026: Mendoza's campaign released its 'spineless' TV ad.
October 7, 2026: Early voting began in the district.
November 3, 2026: Election day; unofficial results expected that evening.
Season Trajectory
This race continues the pattern set by Ciscomani's 2024 win over Kirsten Engel by several points in the same district. The 2026 contest pits the incumbent against a new Democratic challenger, testing whether that prior margin holds.
Voters in Pima and Cochise counties will decide who represents the district in the U.S. House, with control of the chamber at stake. Residents who have not yet cast ballots can check early voting and polling information before November 3, 2026.
The takeaway
Results on election night will be unofficial, so readers should watch for certified totals before drawing conclusions about the race. The contest's margin will indicate whether the district's 2024 result holds in a changed national environment.
What happens next
Unofficial results are expected the evening of November 3, 2026, and certification could take several days or weeks if the race is close.
