A majority of Republicans who describe themselves as "very conservative," 61 percent, say they do not want Chambliss to win the nomination, while just 23 percent of Republicans who identify as conservative say they do. Cain leads Chambliss among Republicans who identify as conservative with 68 percent support to Chambliss's 19 percent.
The poll's findings come a few weeks after Chambliss indicated to a local Georgia radio station that he would be willing to ignore the anti-tax pledge authored by Americans for Tax Reform president Grover Norquist.
"I care more about my country than I do about a 20-year-old pledge," Chambliss told the radio station. "If we do it his way then we’ll continue in debt, and I just have a disagreement with him about that."
The comment provoked strong criticism from conservative Republicans, and shortly after, Erik Erickson, an influential conservative and the editor of the conservative website Redstate.com, made mention of a possible challenge to Chambliss. Erickson eventually decided not to run.
