The 2006 South Carolina gubernatorial election took place on November 7, 2006. Incumbent Republican Governor Mark Sanford won re-election against Democratic State Senator Tommy Moore, becoming only the third Republican governor in South Carolina to win a second term (Robert Kingston Scott and Carroll A. Campbell Jr. were the others). Sanford started the campaign with a double-digit edge over Moore and he maintained that lead to election day. During the course of the campaign, Sanford's approval rating averaged in the mid fifties. In Sanford's re-election victory, he also garnered 22% of the African American vote, which was considered very high for a Republican statewide candidate.
