As of Saturday evening, The Associated Press had projected the outcomes of seven propositions. The eighth, Proposition 141, remained undecided with the "yes" side leading 51% to 49%—a gap of roughly 47,600 votes out of more than 2.2 million cast. The measure would amend the state Constitution to prohibit taxes based on vehicle miles traveled.

The four approved measures—Propositions 316, 317, 318, and 319—were all referred to the ballot by the Legislature.

Proposition 316, which passed with 61.9% of the vote, caps local sales taxes on food at 2%, requires voter approval for any new or increased food sales taxes, and bars changes from taking effect before June 30, 2027.

Proposition 317, approved with 57%, designates drug cartels as terrorist organizations and directs the Arizona Department of Homeland Security to address the threat they pose.

Proposition 318, which passed with 58.9%, prohibits transgender girls from participating on female school sports teams, imposes restrictions on locker room use, and defines a student-athlete's sex as what was listed on their original birth certificate.

Proposition 319, which passed with 62%, prohibits new contracts for camera license plate readers used to enforce traffic laws starting in 2027 and requires local voter approval to continue existing arrangements.

The three rejected measures were also legislative referrals.

Proposition 142, which would have expanded prohibitions on preferential treatment based on race or ethnicity for state agencies and higher education institutions—including mandatory statements in support of race-based diversity, equity, and inclusion efforts—failed with 59.8% voting no.

"We don't want the government telling us what we can and cannot talk about," said Will of the People, a coalition of community groups and unions that campaigned against the measure, in an election night statement.

Proposition 144, which would have required voters to show government-issued identification to cast a ballot, including by mail; banned foreign nationals from contributing to efforts to influence Arizona elections; given voters the option to have early ballots tabulated at polling places on Election Day; and added language to the state Constitution saying only citizens can vote, was rejected with 53.1% voting no.

"Arizonans don't take kindly to politicians trying to take away their ability to vote by mail," Will of the People, which also opposed Prop 144, said in its statement.

Proposition 320, which would have required school districts in Maricopa and Pinal counties—and any other districts with more than 7,500 students—to spend 60% of their operating budgets on direct classroom instruction, failed with 51.9% voting no.

The results reflect a electorate that weighed each measure on its own merits, splitting on proposals that touched on election rules, education funding, and social policy. All 15 Arizona counties had reported unofficial results as of Saturday night, though the tally for Proposition 141 could still shift as remaining ballots are counted.

The ballot measures were part of a midterm election that also saw Democrats win both chambers of the Arizona Legislature for the first time in 60 years, according to projections.
