Democrat Representative Stephanie Herseth has high approval ratings and was easily reelected in 2004, 2006, and 2008. She has announced she will not seek the Governorship or United States Senate, and instead run for reelection in 2010. Herseth may be vulnerable if popular two-term South Dakota Secretary of State Chris Nelson runs. | Democrat Representative Stephanie Herseth has high approval ratings and was easily reelected in 2004, 2006, and 2008.
