AP Decision Notes: What to expect in Arizona’s special congressional election
September 19, 2025
Voters in southern Arizona will send a new representative to Congress after Tuesday’s special election. The election is to replace the late Democratic U.S. Rep. Raúl Grijalva, who died in March of complications from cancer treatment. The winner will serve out the remaining 15 months of Grijalva’s term in the 7th Congressional District, which stretches from Yuma to Tuscon and hugs almost the entire length of Arizona’s border with Mexico. The seat will not decide control of the U.S. House. But the seat is one of two remaining Democratic vacancies that will likely chip away at Republicans’ slender majority in the chamber.
