They're mad at the nuclear dumping decision.
Bush will lose a lot of the Cuban exile vote in Florida too, because of his absurd new restrictions.
I would not say he would loose the vote. The Cubans I have spoken to are for putting more strain on Castro. the loosening of restrictions was done by clinton to help the cuban ecconomy/castro.
Many of the non family who took advantage of the looser restrictions were just university professors who were on a "educational" trip collecting information to come back and speak against the US embargo.
This election is going to be decided by NEW voters.
