I've heard numerous people say this but I don't buy it. Seems she could just wait til 2012. Leftists like Hillary want dems to win, period. They're socialists and want to keep moving the ball (and chain) forward.
I believe she is going to attempt an end run this year. 2008 will be too late for her. Whatever looks she has - it ain't much - will be gone. Plus, Americans have gotten use to seeing "slim" people as their President.
