Republican Jim Risch Wins Fourth Term in Idaho Senate Race
Senator Jim Risch defeated Independent candidate Todd Achilles to secure a fourth term in the U.S. Senate representing Idaho.
Jim Risch won a fourth term in the Idaho Senate race on Tuesday, November 4, 2026. The Republican senator and chairman of the Senate Foreign Relations Committee defeated Independent candidate Todd Achilles to retain his seat.
Decision Desk HQ projected the victory after Risch established a significant lead on election night, maintaining a gap of approximately 30,000 votes by 9:30 p.m. Risch has served in the U.S. Senate since 2009 and previously held roles as the governor and lieutenant governor of Idaho.
The result continues a long-standing political trend in the state, where a Democrat has not won a Senate race since 1974.
