**Arizona voters will decide Proposition 144, a legislatively referred constitutional amendment, on November 3, 2026.** The measure would explicitly limit voting and registration to U.S. citizens, require government-issued ID for all ballots including mail, prohibit foreign national contributions to influence Arizona elections, and allow Election Day voters the option to have ballots tabulated locally. Arizona already restricts voting to citizens by statute and maintains voter ID rules, so the proposal primarily entrenches these policies in the constitution while expanding ID requirements to mail ballots used by roughly 80% of voters. The Republican-controlled legislature referred the measure along party lines, drawing Democratic criticism over potential effects on mail voting access. Recent county-level reviews found only eight confirmed noncitizen voters in Maricopa County amid millions of ballots, mostly tied to legacy system issues. Limited campaign spending and the broader package of changes have shaped trader views on passage.
