Released by Public Policy Polling on March 26, the survey finds her slightly ahead of the leading Republican candidate for South Carolina's 1st Congressional District, and tied with the other.
Republicans Mark Sanford and Curtis Bostic, who’ll compete in a runoff for the GOP nomination next week, both pale in comparison when it comes to voter opinions of the three candidates, as well.
Voters split 43-43 when asked to choose between Colbert Busch and Bostic, with 14 percent undecided.
Against Sanford, she leads 47-45.
A plurality of respondents (45 percent) say they have favorable opinion of Colbert Busch, with 24 percent unsure (31 percent unfavorable)
Only 30 percent have positive opinion of Bostic, however, and just 34 percent for Sanford. The unfavorable receptions of the Republican candidates are notably high, too (42 percent for Bostic, 58 for Sanford).
Despite his higher unfavorable rating, Sanford leads Bostic 53 to 40, according to the poll.
The two are vying for Republican Party nomination in an April 2 runoff election.
The battle between them could be determined by voters who identify themselves as “very conservative.” Bostic is approved by 51 percent of those on the far-right end of this five-point scale; he scores unfavorably from all other ideological groups. Sanford, however, only gets majority approval (54 percent) from those who identify as “somewhat conservative,” and his reception is split 44-45 from “very conservative” voters.
If she faces Bostic in the May 7 final election, Colbert Busch would get approximately 13 percent of the conservative and very conservative votes, according to the poll. Against Sanford, she’d take 17 percent. Roughly one-sixth of those somewhat- and very-conservative voters remain undecided of who'd they choose in either circumstance.
Colbert Busch has distinct leads against both in the categories of moderate, somewhat liberal and very liberal voters.
Public Policy Polling contacted 1,175 likely voters from March 22 to 24 for its study, which has an overall margin of error of 2.9 percent.
