Voters in Arizona's 7th Congressional District are casting ballots in a special election to fill the vacant seat left by the late U.S. Representative Raúl Grijalva, a Democrat who died in March from complications related to cancer treatment. The district, which spans Arizona’s southern border with Mexico, includes portions of Cochise, Maricopa, Pima, Pinal, Santa Cruz, and Yuma counties, as well as parts of Phoenix and Tucson.
