Ballots are secret and voters have the right to vote for any candidate they want. The only time that party affiliation is important in terms of voting is in the case of a political party caucus or a primary election. In those cases, voters must be registered with the political party whose caucus or primary they wish to participate in. Voters have the right to change their affiliation and then participate in the other caucus or primary election by changing his or her political affiliation on the day of the caucus or primary election is held. Voters can only participate in one party's caucus or primary election each time those events take place.

Any registered Iowa voter may apply for an absentee ballot and vote by mail.

If you are voting in person in Iowa, you will be asked to show a valid form of ID before voting at the polls. An Iowa Voter Identification Card is provided automatically by the county auditor to each voter who does not have either an Iowa driver’s license or non-operator ID. Any voter may request an Iowa Voter ID Card by contacting their county auditor’s office.

A voter without one of the above forms of ID may have the voter’s identity attested to by another registered voter in the precinct or may prove identity and residence using Election Day Registration documents.
