Florida (SurveyUSA): Hillary leads Romney by 7

["'Oeps!' De blunders van Rick Perry Indicted"]

This link, which is fairly comprehensive in discussing specific elections, says Democratic presidential candidates "traditionally received only 13 percent to 15 percent of the Florida Cuban vote." That changes beginning with Clinton in 1992 (22%) and especially '96 (35%).

Hillary is actually positioned to Obama's left on Cuba - her book says she privately urged an end to the trade embargo when she was SoS. No idea if that's felt in these numbers.
