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 Idaho, parties decide who may vote in their primaries. As of July 2025, the Democratic Party allows unaffiliated voters to vote in its primary, while the Republican Party only allows voters registered with its party to vote in its primary. Unaffiliated voters can choose to affiliate with a party on Election Day.[3][4][5]

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

This page focuses on Idaho's 1st Congressional District Republican primary. For more in-depth information on the district's Democratic 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 Idaho in 2024. Information below was calculated on April 7, 2024, and may differ from information shown in the table above due to candidate replacements and withdrawals after that time.

Six candidates ran for Idaho’s two U.S. House districts, including two Democrats and four Republicans. That’s three candidates per district, less than in the previous three election cycles. There were four candidates per district in 2022, 3.5 candidates per district in 2020, and 6.5 in 2018.

The total number of candidates that ran for the U.S. House in 2024 is also lower than any other year this decade.

No seats were open in 2024, meaning all incumbents ran for re-election. There was one House seat open in 2018, the only election cycle this decade in which a House seat was open.

Four candidates—one Democrat and three Republicans—ran for the 2nd Congressional District, the most candidates that ran for a seat in 2024.

One primary—the 2nd Congressional District Republican primary—was contested in 2024. One primary was contested in 2022 and three primaries were contested in 2020.

Rep. Michael K. Simpson (R-2nd) was the only incumbent in a contested primary in 2024.

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