Herman Cain stumps in Miami...ends up getting stumped by questions on Cuba

Overheard on the Herman Cain campaign bus shortly before its arrival in Miami Wednesday....
Cain: OK guys, tell me again about Miami.

Campaign aide: Well, Herman...Miami is very important. Cuban-Americans make up a good part of the population. Most Cuban-Americans are Republicans. Miami also happens to be in the state's most populous county. So, we need the Cuban vote if we want to win Florida.
