The businessman, author, talk radio show host and tea party darling knows how to wow a conservative gathering.
Now the 65-year-old Cain will try to see if he can use that grass-roots enthusiasm to turn a long-shot presidential campaign into a realistic bid.
He plans to announce his candidacy at a rally in Atlanta on Saturday, an announcement that's hardly a secret. Cain has been crisscrossing the country for months now, his intentions abundantly clear.
