It's unclear whether Cain's endorsement will help former House Speaker Gingrich, who is trailing Mitt Romney by a wide margin in the latest Florida polls.

A poll by the

Miami Herald

gives Romney an 11-point lead, while a Rasmussen poll released Sunday morning has the former Massachusetts governor up by 16 points, according to a report by the

Atlanta Journal Constitution


Cain was the Republican front-runner briefly last fall, but he bowed out of the race following allegations of sexual harassment and adultery.
