Polling places across Arizona closed their doors at 7 p.m. MST on July 21, 2026, marking the start of a long night of counting and waiting. Voters cast ballots in a series of high-stakes primaries, including races for the U.S. House and the State House and Senate. The results, trickling in from counties statewide, began painting a picture of which candidates would advance to the general election.
In Maricopa County, election officials reported smooth operations at most precincts, though a few isolated technical glitches caused minor delays. The county, home to over 60% of the state’s voters, is expected to be a bellwether for several competitive districts. Early returns showed tight contests in the 1st and 6th Congressional Districts, where incumbents face challengers from both parties.
Meanwhile, in Pima County, turnout appeared robust, with long lines reported at several polling stations in Tucson. Local party activists expressed cautious optimism about their candidates’ chances. The race for the State Senate in District 10 has drawn particular attention, as both major parties vie for control of the chamber.
As the evening wore on, the state’s automated tabulation centers began processing mail-in ballots, which make up a significant portion of the vote. Election officials emphasized that results would be updated periodically throughout the night. For now, the picture remains incomplete, but early trends suggest a competitive night ahead for Arizona’s political landscape.
