In a primary election, no candidates are elected. Instead, voters who are affiliated with political parties nominate their candidates to run in the general election. Only voters affiliated with a political party may vote, but any Iowa voter may declare or change party affiliation at any time. Currently, Iowa has three groups with full political party status: the Democratic, Republican, and Libertarian parties.
