The Arizona Supreme Court has ruled that votes for Proposition 140, which proposes an open primary system, will be counted despite challenges regarding the validity of signatures. This measure, known as the Make Elections Fair Act, would allow all registered voters to participate in primaries, irrespective of party affiliation, with the top candidates moving on to the general election. Opponents argued that nearly 40,000 signatures were duplicates, which would disqualify the measure from the ballot. However, the court upheld a lower court's decision, stating that there was no legal basis to stop counting the votes. The ruling comes just weeks before the election, amidst concerns about disenfranchising voters. The outcome of this measure could significantly alter Arizona's electoral landscape by reducing partisan influence and introducing ranked-choice voting.
