Romney, the national front-runner and a familiar face in Iowa after his 2008 presidential run, attracts support from 23 percent of likely Republican caucus-goers. Bachmann, who will officially kick off her campaign in Iowa on Monday, nearly matches him, with 22 percent.
“She’s up there as a real competitor and a real contender,” said Republican pollster Randy Gutermuth, who is unaffiliated with any of the presidential candidates. “This would indicate that she’s going to be a real player in Iowa.”
Former Godfather’s CEO Herman Cain, who has never held public office but has found a following among tea party supporters, comes in third, with 10 percent.
The other candidates tested register in single digits: former U.S. Speaker of the House Newt Gingrich and Texas Rep. Ron Paul, 7 percent each; former Minnesota Gov. Tim Pawlenty, 6 percent; former Pennsylvania Sen. Rick Santorum, 4 percent; and former Utah Gov. and ambassador to China Jon Huntsman, 2 percent.
