2022 United States Senate election in Idaho
The 2022 United States Senate election in Idaho was held on November 8, 2022, to elect a member of the United States Senate to represent the state of Idaho. Incumbent Republican Senator Mike Crapo was first elected in 1998 [United States Senate election in Idaho|1998] and ran for re-election to a fifth term in office. Primary elections were held on May 17, 2022. Crapo easily won renomination, while former Idaho House of Representatives candidate David Roth won the Democratic primary with 57.8% of the vote. Crapo ultimately won the election, but this was the lowest share of the vote he had ever received for this seat, partially because of an independent candidate, Scott Cleveland, taking away some of his votes.
The election resulted in both the worst performance by a Republican, and the best performance by a Democrat in the Class 3 seat since 1992 [United States Senate election in Idaho|1992]. It was also the best performance by a third-party or independent candidate since Glen H. Taylor's write-in campaign in 1956.
