If Hillary made a principled stand..let’s say, resigning out of principle, she’d could very well become the de facto leader of the Democrat party and set up well for 2010. HELL, anyone who steps up will have a head start. This is a freaking trainwreck.
...or a strategy. Perhaps Clinton is content to sit back and watch him self destruct. It was, after all, mentioned as her only chance for 2012 after it became apparent she would not get the nomination this time.
