COLUMBIA - A second former candidate has announced her support for Sally Atwater in the Superintendent of Education race which is headed for a runoff.

Amy Cofield, who was vying for the Republican nomination of Superintendent of Education, endorsed Atwater's campaign on Friday. Gary Burgess, another former candidate, announced his support for Atwater on Wednesday.

"Sally is a strong Republican, someone who will not stop until common core standards are a thing of the past," Cofield said. "She supports more choices in education and will make a strong Superintendent of Education."

Atwater and Molly Spearman both received 22 percent of the primary vote Tuesday night - beating out six other Republican candidates. A runoff election will be held on June 24.
