An appearance by G-O-P presidential candidate Herman Cain that was scheduled for this evening in Charlotte County was canceled — not through lack of interest but because Cain is down with the flu. The pizza entrepreneur had scheduled an appearance at the Charlotte County Cultural Center but it, along with several other Sun Coast appearances, were canceled today when the candidate became ill. Earlier, some four hundred Cain supporters turned up for a rally in Bradenton but had to go home disappointed.
