While what you say is a concern, keep in mind that many of those early vote ballots were also cast on the heels of Newt’s blow out victory in South Carolina that lasted for a few days before Bloody Thursday of this week. Romney came into Florida with at least a limp after SC. :)
Let’s hope so but I fear a lot of them were the result of Romney’s early organization in FLA before Newt could get his together after SC
