Can I take my absentee ballot to the polls on Election Day and vote there?
Yes. If you have not returned your absentee ballot you may go to your polling place on Election Day and vote a regular ballot.
Can an independent vote in a primary election?
Yes and No. In Iowa, you must be a member of a political party (currently: Republican and Democratic) to vote in a primary election. However, anyone* can change parties on Election Day and vote. For independents to vote they must declare a political party.
*Precinct election officials may not change political parties within 30 days of an election.
