War is McCain's biggest problem in 2008

The real barrier to John McCain’s presidential ambitions "may be his unswerving, unstinting and unnuanced support for an unpopular war in Iraq," reports Bloomberg."

With only 38 percent of Americans in the Bloomberg/Los Angeles Times poll saying the war is worth fighting, McCain's advisers are trying to make a virtue of his stance, saying it shows he is genuine, courageous and un-political."

Says McCain: "I do understand it could be a political liability."

**McCain also needs some Red Bull to get that "I just came out of a hospital" look off his face.
