McCain believes by talking about nothing, being bland, ignoring reality, being polite, and praising Obama, he will attract the 4 or 5 % of the voters who claim to be independent or undecided and they will make him POTUS.
He is wrong, but nobody has the balls to tell him that. Plus he's to bullheaded to listen even if they did.
How did we wind up with that boring, stiff, bland, uninteresting bureaucrat as our candidate when we had Rudy and Romney, who would have taken the gloves off and Obama would have been a footnote rather than president elect.
