AINews Summary
Jim Risch has secured the Republican nomination for Idaho’s 2028 Senate race. David Roth won the Democratic nomination, and Todd Achilles is also in the race as an independent. Idaho’s strong Republican lean keeps the GOP favored heading into the general election. Risch’s primary win likely reinforces Republican strength in the race. The independent candidacy adds a little uncertainty, but the overall outlook still appears GOP-favored.
