A right-leaning poll released Thursday shows the First Congressional District race between Republican Mark Sanford and Democrat Elizabeth Colbert Busch to be tied.
Red Racing Horses shows both candidates at 46 percent with seven percent of the voters still undecided. The poll has a margin of error of five percent.
The poll was conducted between April 29 and May 1, which means some portions of it were after the candidates' first and only debate on Monday.
The pollsters contacted 5,000 people in SC1 and asked six questions about the race. According to Red Racing Horses respondents "that indicated a disinclination to vote on May 7 or did not complete the six-question survey were not counted as part of the results."
Sanford had a five percent edge among men, while Colbert Busch had a four percent lead among women.
Colbert Busch fared the best in Beaufort County where she had a 52-39 lead. She also led in Charleston County by four percent. Sanford had leads of 20 and 13 percent in Berkeley and Dorchester County, respectively.
Red Racing Horses said, "The closeness of the race in the normally Republican district is almost certainly due exclusively to Republican ex-Gov. Mark Sanford's personal issues. Problematic for Sanford is the suggestion that some of his core voters, particularly Social Conservatives in the suburban Charleston area, may stay home Tuesday."
