No candidates are elected in a primary election. Instead, the state's two official parties (Democratic and Republican) choose their candidates for the November 4 general election. Note that president does not appear on the primary ballot, as Iowa instead held its first in the nation caucuses on January 3.
Voters must be registered with a political party to vote in that party's primary. However, you can change your party affiliation at any time, including Election Day.
