The Herman Cain surge: why he rose (not Mitt Romney) as Rick Perry slid

Herman Cain is on a roll in the GOP presidential sweepstakes, and it’s not hard to see why. The former CEO of Godfather’s Pizza is an affable, upbeat outsider with a record of success in business. Most important, he is focused on the issue voters care about most – the economy – with his “9-9-9” tax plan.

When Texas Gov. Rick Perry stumbled in debates and descended from his front-runner perch, Mr. Cain was there to pick up the slack. He notched a surprise victory against Governor Perry in the Florida straw poll Sept. 24, and Cain is now second in national polls, behind former Massachusetts Gov. Mitt Romney. In CBS News’ latest survey, he and Mr. Romney are tied for first.

The fact that many disaffected Perry voters went to Cain and not Romney – the Republican who polls best against President Obama – is telling. Romney also has an economic proposal, his 59-point jobs plan. But he has allowed himself to get caught up in point-scoring with Perry over Social Security and immigration, and away from his core economic message. And many conservatives still don’t trust Romney, who continues to defend his Massachusetts health-care reform, a model for Mr. Obama’s reform.

Political analysts still call Cain a long-shot for the GOP nomination. But the race remains fluid, and now is his opportunity to build on his momentum.

"There’s a door open such that people are willing to look at him and his accomplishments,” says Republican pollster David Winston. “Voters want candidates who say what they’ll do and try to lay out solutions.”

Still, Cain has had his moments of distraction. He has faced criticism for saying he wouldn’t put a Muslim in his Cabinet. And as the only African-American in the GOP race, he has gotten attention for calling Perry’s racially named hunting lodge “insensitive,” then backing away from the comment, then repeating it.

Cain’s decision to shift to a long-planned book tour to promote his new memoir, “This is Herman Cain!,” has been derided as a sign he’s not serious about running for president, just selling books. But that may be a distinction without a difference.
