Utah is the only state in which no one can run in a major party primary, if that individual doesn’t receive substantial support first at a party meeting. An initiative has been submitted that would change the law, and provide that a normal primary be used for all nominations. Mitt Romney has endorsed that initiative. See this story. The story also reveals that Romney’s letter says he has been actively working to persuade all states to move to presidential primaries, and away from presidential caucuses.
