Currently, Utah only holds party primaries when at least two candidates get 35% support at a party caucus. Candidates who don’t have that much support in party caucuses can’t run for party nominations. Plans are being made for an initiative that would eliminate the role of party caucuses in choosing nominees. All candidates seeking a party nomination would simply file to be on the primary ballot. The initiative would continue to let parties decide who may vote in their primaries. The initiative is due April 15, 2014. See this story, which uses the term “open primary” to mean a primary in which primaries are the sole determinant of party nominations.
