This page focuses on the Republican primaries that will take place in Iowa on June 2, 2026.
A primary election is an election in which registered voters select a candidate that they believe should be a political party's candidate for elected office to run in the general election. They are also used to choose convention delegates and party leaders. Primaries are state-level and local-level elections that take place prior to a general election. In Iowa, state law provides for a closed primary where every voter must be affiliated with a party in order to participate in its primary. However, a voter can change his or her political party affiliation on the day of the primary.[1][2]
For information about which offices are nominated via primary election, see this article.
