The Idaho Open Primary measure or Idaho Proposition 1 was a ballot initiative in the state of Idaho that was defeated on November 5, 2024, as part of the 2024 United States elections. If enacted, the initiative would have ended Idaho's system of closed primaries, replacing it with a top-four primary, and implement a ranked-choice voting system for the general election to replace the current plurality voting system. This would apply to congressional, gubernatorial, and state and county elected offices. Top-four primaries with ranked-choice general elections are currently in use in Alaska. The proposition was certified for the ballot on July 10, 2024.
