Primaries vs. general elections

  • Primary elections are conducted to select each party’s candidates in the general election.
  • In Idaho, each party chooses whether to participate in a primary and which voters will be allowed to vote in a primary election and must file the decision with the Secretary of State no later than the last Tuesday in November the year prior to the presidential primary. 
  • At the poll during a primary election an unaffiliated voter may choose a party ballot in order to vote in that party’s primary. However, if you choose a party ballot, state law allows for the affiliation on your registration to be changed
  • In a general election, voters are not required to have a party affiliation.
