v t e

The 2010 United States Senate election in South Dakota was held on November 2, 2010 along other elections to the United States Senate in other states as well as elections to the United States House of Representatives and various state and local elections. Incumbent Republican U.S. Senator John Thune won re-election to a second term unopposed.^[1][2]

Background

Thune was narrowly elected to his first term over Democratic Senate Minority Leader Tom Daschle with 51% of the vote in 2004. In spite of his lack of seniority, Thune rose to the position of chairman of the Republican Policy Committee in the United States Senate.

No members of the South Dakota Democratic Party (or any other party) filed to challenge Thune. Scott Heidepriem, the South Dakota Senate Minority Leader and a Democratic candidate for Governor of South Dakota, said, "We just concluded that John Thune is an extremely popular senator who is going to win another term in the Senate."^[3] There were approximately 90,000 undervotes compared to the concurrent gubernatorial election.
