2010 South Carolina gubernatorial election

The 2010 South Carolina gubernatorial election took place on November 2, 2010. Incumbent Republican Governor Mark Sanford was term limited and unable to seek re-election. Primary elections took place on June 8, 2010, and a runoff election, as was necessary on the Republican side, was held two weeks later on June 22.

Republican Nikki Haley defeated Democrat Vincent Sheheen in the general election by a margin of 4.5%. As of 2023, this is the closest that the Democrats have come to winning the governorship of South Carolina since their last victory in 1998. This is the first open-seat election since 1994. Haley was re-elected in 2014 in a rematch with Sheheen.

Republican primary
According to CNN, Haley initially entered the gubernatorial primary as a dark horse candidate. In an article covering her surge in the primary in the weeks prior to the election, it was noted that a "surprise" endorsement from former Alaska governor and 2008 vice presidential candidate Sarah Palin boosted Haley's candidacy. Haley's campaign was backed by TV ads run by ReformSC, an advocacy group funded by allies of outgoing governor Mark Sanford.

Other Parties

 * Morgan Reeves, Businessman, Minister, and retired National Football League player from Irmo
 * Dr. Reeves was nominated on March 30 by the United Citizens Party and South Carolina Green Party on April 7 (see SC Election Commission website). Reeves appeared on the November 2nd general election ballot for both parties. An Independent, Dr. Reeves collected enough voter petition signatures to qualify by the July 15th deadline onto a 3rd ballot line.
 * Jim Rex, State Superintendent of Education from Fairfield County
 * Rex was nominated by the Working Families Party prior to losing the Democratic primary. Rex did not appear on the Working Families ballot line in November due to South Carolina's "sore loser" law that requires candidates not to seek nominations from multiple parties from appearing on the ballot after they lose any one party's nomination (see candidate party pledge forms).  Several election law issues are before US appellate court in Richmond, Virginia regarding conformity to the 1965 Voting Rights Act and US Constitutional provisions, see ACLU/Platt v SC
