The 1996 United States Senate election in Wyoming was held November 5, 1996. Incumbent Republican U.S. Senator Alan K. Simpson decided to retire. Republican nominee Mike Enzi won the open seat. This is the last time a Democrat won 40% of the vote in a Wyoming Senate Election. Indeed, only one subsequent Democrat has scratched even 30%, and then only barely-- Nominee Gary Trauner in the 2018 wave year received 30.10% of the vote.
