McCain vs. who? There are a lot of dorky potential candidates in either party he would easily defeat. He's getting a little old, but he is always a viable candidate worthy of voter consideration.
His health is a problem, as is his age, even before you look at his record.
McLame as about as much chance of beating the potential candidates, as does Pataki...NONE! Heck, Pataki would beat McQueeg now and nobody want Pataki.
There are always people stupid enough to vote for him.
What, you think only the people on FR know he's insane?
Nope. That's precisely why the MSM loves him, because he's an off-the-wall, mercurial, newsmaking kind of oddity.
McCain as 2008 nominee is ridiculous, not worthy of serious discussion.
