Personally, I wouldn't vote for McCain, or his obvious brain tumor, in a million years.
I can't do the lessor of two evils thing anymore, but even if we were to play that game, who is to say that an egomaniac like McCain isn't more dangerous to our liberties. I would think (and hope) that a GOP congress would stop her at least as much as they did her HINO.
One thing for sure, the right was much more united and vigilant against clinton. Bush has divided us and there has been a lot of garbage that became law under him that would have never become law under clinton.
