Alaska law allows a recognized political party to select who may participate in their party's primary. Parties may expand or limit what political affiliations may participate in their primary election by submitting a written notice to the director of elections no later than September 1st of the year prior to the year in which a primary election is to be held.
The political party affiliation listed on a voter's registration record 30 days prior to the election determines which primary ballot type a voter is eligible to vote. Currently there are three primary ballot options:
Alaska Democratic Party and Alaskan Independence Party Candidates with Ballot Measures ballot and any registered voter may vote this ballot.
Alaska Republican Party Candidates with Ballot Measures ballot. Only voters registered with the party affiliation of Republican, Nonpartisan or Undeclared may vote this ballot.
Ballot Measures Only ballot and any registered voter may vote this ballot.
