The 1968 United States Senate election in South Dakota took place on November 5, 1968. Incumbent Democratic Senator George McGovern ran for re-election to a second term. He was challenged by former Governor Archie M. Gubbrud, who was persuaded to enter the race by the South Dakota Republican establishment.[1] McGovern defeated Gubbrud by a wide margin, even as Richard Nixon was defeating Hubert Humphrey in the state's presidential election in a landslide.
