Mundt Republican Party (United States) Karl E. Mundt Republican Party (United States) The 1966 United States Senate election in South Dakota took place on November 8, 1966. Incumbent Republican Senator Karl E. Mundt ran for re-election to his fourth term. He was challenged in the Republican primary by a John Birch Society member, but easily turned away the challenge. In the general election, he faced State Representative Donn Wright, the Democratic nominee. Owing in large part to the Republican landslide taking place nationwide, Mundt defeated Wright by an unprecedented margin. South Dakota would not elect another Senator to a fourth term until John Thune in 2022, it was dubbed the "Mundt curse".Sen. John Thune broke the Mundt curse. Now, can he become the Senate GOP top dog? https://argusleader.com/story/news/politics/2022/11/16/south-dakota-us-senator-john-thune-election-2022-win-is-set-for-senate-gop-leadership-future/69635295007/ 2024-11-13 subscribe.argusleader.com Democratic primary State Representative Donn Wright from Aurora County announced that he would run against Mundt on April 18, 1966, the only Democratic candidate to do so.April 18, 1966 Donn Wright Is Demo Candidate For U.
