No. You cannot register at the polls. You must be registered at least 30 days before the election.
I am registered to vote in Alaska, but I am leaving for college and will not be back until after the elections. Can I vote?
Yes. For federal and state elections, you may apply for an absentee ballot by following the instructions on the website of the Alaska Division of Elections.
City and borough elections are conducted by the local government. To vote an absentee ballot in these elections, apply directly through your city or borough clerk.
