What's at stake
For the country
- This seat is held by Republicans. A Democratic win would be a flip, one of the 4 net gains Democrats need to reach 51 seats and take control.
- A Republican hold keeps it in the column that protects the current 53-seat majority.
- Senate control decides which judges and cabinet nominees are confirmed and whether the President's bills can pass.
For Idaho
- Senators vote on every federal law, confirm Supreme Court justices, federal judges and cabinet members, and ratify treaties. Terms last six years.
- Jim Risch is the incumbent. Incumbents bring seniority, name recognition and committee roles; challengers argue for a fresh start.
Todd Achilles
- Todd Achilles runs as an independent and is not bound to either party's platform; Democrats are backing the campaign.
Jim Risch
