Primary Type Definitions



  • Indiana has nonpartisan registration. There is no option to affiliate with a political party on the voter registration form.


Details of voting in congressional and state primary elections:

  • Affiliation with a party is not required to vote in primaries. However, voters can only choose the primary ballot of the party who recieved a majority of their votes in the previous general election, and voter records are kept as public information.
  • If a voter did not vote in the last general election, they must "intend to vote for the majority of the nominees on their desired party's ballot."
  • Voters can be challenged by another eligible voter on suspicion of perjury.
  • This system is an attempt to get voters to vote along party lines, but is not easily enforceable.
