Republicans Poised to Hold Idaho’s 1st District

Republicans appear set to keep control of Idaho’s 1st Congressional District in the 2026 midterm elections, preserving the party’s hold on one of the state’s most reliably conservative House seats. The district, which covers the growing population centers in northern and western Idaho, has long favored Republican candidates in federal races.

As the campaign cycle takes shape, the GOP is likely to enter the race with a structural advantage built on the district’s voter registration trends, recent election history, and strong alignment with the party’s platform. Unless Democrats mount an unusually strong challenge, the seat is expected to remain in Republican hands after ballots are counted on Election Day.
