Arizona's 6th congressional district House race between Republican incumbent Juan Ciscomani and Democratic challenger JoAnna Mendoza stays tightly contested ahead of the November 3 election, with recent polls showing Mendoza ahead by 2–4.5 points inside margins of error. The district's even partisan voting index and historical narrow margins sustain uncertainty, while Mendoza's fundraising edge and stronger early ballot returns among Democrats have supported trader pricing around modest Democratic victories in the 3–9 point range. Forecasters have shifted ratings toward Lean Democratic in recent weeks amid limited late-cycle polling, yet the race's competitiveness and potential Election Day turnout shifts leave room for outcomes across several margin bands.
