The 1994 United States Senate election in Michigan was held November 8, 1994. Incumbent Democratic Senator Don Riegle decided not run for re-election. Spencer Abraham won the open seat, becoming the first and so far only Republican to win a U.S. Senate race in Michigan since Robert P. Griffin in 1972 and the first to win the state's Class I seat since Charles E. Potter in 1952. As of 2024, this is the last time that a man won the Class 1 Senate seat in Michigan.
Riegle, a three term incumbent, was considered one of the most vulnerable Senate Democrats in the 1994 mid-term elections, due to the unpopularity of President Bill Clinton[1] and his being involved as a member of the Keating Five, a group of five United States Senators who were accused of corruption. After months of speculation, Riegle announced he would not seek a 4th term in a speech on the Senate floor.[2]
