South Carolina Republicans like former Florida governor John E. “Jeb” Bush for president, while continuing to support Sen. Lindsey O. Graham for re-nomination against a host of conservative challengers, according to the March 6-7 Human Events/Gravis poll of 735 voters, who had previously voted in a Republican primary.

“Jeb Bush shows strength across many of the poll’s crosstabs and was the choice of 22 percent of the respondents compared to his 16 percent in our November poll,” said Doug Kaplan, the president of Gravis Marketing, the Florida-based polling company.
