The 1993 United States Senate special election in Texas was held on June 6, 1993, to replace Democratic U.S. Senator Lloyd Bentsen, who had resigned to become Secretary of the Treasury. Governor Ann Richards appointed Democrat Bob Krueger, a Texas Railroad Commissioner, to fill the seat. Krueger ran in the special election, but was defeated in a landslide by Republican Kay Bailey Hutchison. The nonpartisan blanket primary was held on May 1, 1993. Since no candidate received a majority in the primary, a runoff was held on June 6, 1993.
Hutchison was the first Republican to win this seat since Reconstruction in 1875 and the first Republican ever to be popularly elected at this seat. It was the first time since then that Republicans held both of the state's Senate seats simultaneously. This is the last time a Senator from Texas lost re-election. In 2010, Krueger's campaign was named by the Houston Chronicle as the worst in Texas' modern political history. Hutchinson became the first woman to serve as a senator from Texas.
