I don't know that I'd write McCain off. When you look at how easily Obama won all of the states in the deep south, he won it with upwards of 90% of the black vote. I think he'll get the same number of votes down there in general that he got in the primary. Everybody else will either not vote for president, stay home, or go for McCain.
          Personally, I've been thinking of voting for everything on the ballet except the office of president, and just leaving that blank, or voting for the Green candidate.
