“These latest allegations against Sanford have led a number of those voters who were on the fence to not plan to vote at all or to switch sides to Colbert Busch,” said Kendra Stewart, a political scientist at the College of Charleston.

“She has an advantage among independents, and she is actually pulling some Republicans, especially Republican women,” Stewart said.

College of Charleston political scientist Gibbs Knotts said Colbert Busch held her own against her more seasoned opponent.

“She did a really good job of going after him, which can galvanize those folks that are on the fence and also motivate her base,” he said.
