Yes, but Castro is getting a bit long in the tooth. I believe that most progressive Democrats would be just as happy with Hugo Chavez, and he is much younger.
A "Draft Chavez in 08" campaign would probably go over well with the same folks that were happy with a Senator Kerry candidacy.
Heh....that would make a great thread.......lining up all the sure-loser candidates the Dims might be forced to use.
