Details of voting in congressional and state primary elections:

  • Voters must affiliate with a party to participate in that party's primary.
  • An unaffiliated voter may choose one party's ballot, which makes them a registered member of that party. However, temporary affiliation is possible, as voters can fill out a card at the polling place to return to undeclared status after the vote is cast. For this reason, New Hampshire allows same day registration for unaffiliated voters.
