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 Election Day, creating what is effectively an open primary.[3]

For information about which offices are nominated via primary election, see this article.

This page focuses on Iowa's 1st Congressional District Democratic primary. For more in-depth information on the district's Republican primary and the general election, see the following pages:

Post-filing deadline analysis

The following analysis covers all U.S. House districts up for election in Iowa in 2024. Information below was calculated on April 19, 2024, and may differ from information shown in the table above due to candidate replacements and withdrawals after that time.

Eleven candidates ran for Iowa’s four U.S. House districts, including five Democrats and six Republicans. That’s 2.75 candidates per district, higher than the 2.5 candidates per district in 2022 but lower than the 4.5 candidates per district in 2020.

No seats were open in 2024, meaning all incumbents ran for re-election. One House seat was open in 2020, and two were open in 2014, the only two years this decade in which House seats were open.

Three congressional districts—the 1st, the 3rd, and the 4th—were tied for the most candidates running for a seat in Iowa in 2024. Three candidates ran in each district.

Three primaries—one Democratic and two Republican—were contested in 2024. That’s more than the one primary that was contested in 2022 but less than the four primaries that were contested in 2020.

Two incumbents—Mariannette Miller-Meeks (R-1) and Randy Feenstra (R-4)—were in contested primaries, tying with 2016 for the most this decade.

Candidates filed to run in the Republican and Democratic primaries in all districts, meaning no seats were guaranteed to either party.
