CHARLESTON, S.C. - In her quest to win the White House, Michele Bachmann needs voters like Barbara Bates more than ever.
Bates is a fervent Tea Party member on the crucial GOP turf of South Carolina, where Bachmann is working to extend her Midwestern Bible Belt appeal.
Bates and her husband, retirees in the coastal community of Goose Creek, have been paying very close attention to the GOP presidential field this summer. They have been regulars at many of the Palmetto State's big GOP gatherings, including Texas Gov. Rick Perry's presidential announcement on Aug. 13 and at least two of Bachmann's recent town halls.
"I have not heard her say anything that I disagree with," Bates said. But she and her husband, Bill, retired from the Navy, are still up for grabs, with Perry tugging at the loyalties of their deeply conservative hearts.
How to decide? "Electability is going to have to factor into it," Bates said.
With Perry surging in South Carolina, Bachmann is struggling to lay the foundation of a national campaign that can compete for money and resources with two of the GOP's top candidates -- Perry and former Massachusetts Gov. Mitt Romney.
Florida and other big states loom large, but South Carolina appears to be the firewall where Bachmann must lay to rest the questions about whether her campaign can go all the way. Those questions have intensified with the entrance of Perry, who matches Bachmann's faith-centered, small-government politics, with an added measure of executive experience to boot.
"The early stage of the campaign is the party checking out the ideological credentials of their candidates," said former U.S. Rep. Vin Weber from Minnesota, who switched over to Romney after helping former Gov. Tim Pawlenty's now-defunct presidential campaign get going. "But as you move forward in the process, questions of electability and plausibility as president loom a little bit larger."
