State Rep. B.R. Skelton announced Tuesday he would not seek reelection in November.
The Republican from Pickens County had one of the most controversial elections in 2012, when he lost to primary challenger Ed Harris only to have the election results thrown out because of a state Supreme Court decision. Harris later got his name on the ballot again as a petition candidate, but lost.
Skelton, an economic professor at Clemson, has served in the House since 2003.
He is the third GOP lawmaker to announce his retirement this year.
Reps. Liston Barfield, R-Horry, and Roland Smith, R-Aiken, also said they would not seek re-election this fall.
