JoAnna Mendoza leads Juan Ciscomani in the Arizona 6th congressional district race heading into the November 3, 2026 general election. Recent October polls, including a RedBox Research survey of likely voters, show Mendoza ahead by roughly four points, consistent with a modest polling edge in a district rated Lean Democratic by forecasters such as the Cook Political Report. Mendoza has maintained a substantial fundraising advantage, reporting over $11 million raised compared with Ciscomani’s roughly $7.6 million through mid-October filings. The incumbent Republican won the seat by narrow margins in 2022 and 2024, but shifting voter sentiment in this evenly divided district has produced the current trader consensus reflected in prediction market pricing. No major late-October events have altered the trajectory established by these polling and financial trends.
