Iowa has multiple options for voter registration for the June 2nd state primary election. You can register to vote-by-mail through May 21st, or in-person through May 22nd. Voters with in-state IDs may also use the online system to register through May 25th. If you would prefer to vote-by-mail, you must submit an application by May 22nd, no excuse required.
Only voters who are registered with a particular party may vote in its caucus, but voters may change party affiliation on the day of the caucus. See Iowa Republican Party or Democratic Party sites for more details, including caucus sites.
Some congressional seats, state offices and constitutional amendments may be included on the ballot.
