It is probably a pretty good chance that these reports of "long lines" are a bunch of crap, hoping that legitimate, concerned voters stay home. They know damn sure that the people they "bus in" aren't going to wait around for a couple of hours.
Also, expect Jeb to run better in South Florida than his brother did two years ago. Cubans are motivated, as are other Hispanics, to vote for Bush. AA turnout was monster two years ago, and Gore still didn't win the state.
If Bush does as good among white females as he is doing, is killing McBride among white males, and wins Hispanics as I suspect he will, then Bush will win going away. The only doubt will be the margin.
Be Seeing You,
