The 1992 United States Senate election in Idaho took place on November 3, 1992, alongside other elections to the
United States Senate in other states as well as elections to the
United States House of Representatives and various state and local elections. Incumbent
Republican U.S. Senator
Steve Symms decided to retire instead of seeking a third term. Republican nominee and
Boise mayor
Dirk Kempthorne won the open seat, defeating Democratic Congressman
Richard H. Stallings.
To date, Stallings' 43 percent is the last time that the Democrats have won more than 40 percent of the vote in a Senate election in Idaho. This was the first open-seat Senate election in Idaho for this seat since
1903.
