He has nothing to gain by endorsing either candidate. By not endorsing he keeps the potential for being the VP nominee of the winning campaign.
His presence on the ticket opens some space for the Democrat by putting Arizona, Florida, and Texas into doubt, forcing the GOP to throw money and clout into those states.
I don't think we're going to win Florida, simply because of the fact that it's more conservative than people tend to think. To win Florida, you need to come out a few hundred thousand votes ahead in Greater Miami, which is tough. And you also need to win swing cities like Orlando and Tampon Bay by decent margins.
Clinton's strength would be with older women showing up big, potentially, while Obama potentially brings large black turnout in key GOP areas like Jacksonville and perhaps shaves some anti-war military votes from McCain. The last poll I saw showed soldiers were even more anti-war than the general public, so there's potential to capitalize on it, breaking the typical 80/20 GOP advantage.
But, even with all that, Florida would be a dogfight. McCain will get huge turnout in the panhandle, between Tallahassee and Mobile. (Tallahassee, itself, will go 2/3s for the Dem no matter what, but it's everything to the West that will be solidly McCainiac territory.)
