Arizona's 6th congressional district remains a toss-up between Democratic challenger JoAnna Mendoza and Republican incumbent Juan Ciscomani, with limited recent polling showing margins under three points and forecasters rating the seat competitive ahead of the November 3 general election. The district's narrow partisan balance, reflected in 2024 presidential results and mixed voter sentiment on economic and border issues, has kept both candidates within striking distance despite Mendoza's fundraising edge and some surveys showing her slight lead. High spending by outside groups on both sides, combined with standard midterm turnout patterns in Pima, Pinal, and Cochise counties, sustains the closeness reflected in trader pricing across narrow margin buckets. Late-cycle advertising, any final debate exchanges, or shifts in national conditions could still widen or narrow the outcome before ballots are cast.
