There was no change in the 1st Congressional District Republican primary outcome after the State Election Commission certified the recount results Friday.
The final tally still means second-place finisher Curtis Bostic will face first-place finisher Mark Sanford on April 2 for the GOP nomination.
Election Commission spokesman Chris Whitmire said the only change after the mandated recount was that third-place finisher Larry Grooms picked up one vote, in his home Berkeley County.
The addition came after officials discovered one ballot had been misread because of a scanning issue in which no vote was recorded.
The results gave Sanford 36.9 percent of the vote to 13.3 percent for Bostic and 12.4 percent for Grooms.
The recount was held because the margin between Bostic and Grooms was less than 1 percent.
On the Democratic side, Elizabeth Colbert Busch was certified as the winner of the party primary, getting 96 percent of the vote to 4 percent for Ben Frasier.
Also Friday, Sanford was endorsed by Jeff King, who also had sought the nomination. King is the third candidate to back Sanford since Tuesday. The others are Elizabeth Moffly and Keith Blanford.
