What other types of primaries currently exist?

There are several other types of primaries, although some states use hybrid versions of these systems (click here for a state by state breakdown)

  • Closed: Independents cannot vote in a party primary, unless party votes to open it for a specific election.
  • Open: There is no partisan voter registration. Voters must choose a party primary in which to vote.
  • Semi-Closed: Independents or unaffiliated voters can vote in a party primary. However, they must reregister into a party on that day. Some states require a waiting period to reregister such as CO and ME. Other states such as NH and RI allow you to reregister at the poll. Parties can elect to bar independents from participating.
  • Semi-Open: Independents or unaffiliated voters can vote in state primary. They must ask for a party ballot, and can only vote in that party primary. Parties can elect to bar independents from participating.
