Online voter registration is permitted in Alaska.  Voters can also submit a paper registration form in person or by mail to the Division of Elections Office or a voter registration agency. In Alaska, parties determine who may vote in their primary elections. The Alaska Democratic Party and Alaskan Independence Party allow any registered voters to participate in their primaries. The Alaska Republican Party allows only registered Republicans, nonpartisan voters, or undeclared voters. Your vote is valuable to the state and makes a difference!
