McCain in my opinion is nothing like Bush.

McCain is in the middle, he is far from being a Conservative Republican (not that Bush is a real Republican, he's a bit Liberal in some of his stances). McCain has screwed Republicans left and right. He's not really getting cozy with Bush and I doubt he will. Taking a few pictures with him does not qualify as anything special.

He'll get money from the Conservative Republicans when it comes down to it however. Republicans don't like McCain but they hate Obama a hell of a lot more.
