I think she's all the D's have and will therefore be their candidate. Bill will survive and manage her campaign for her.
Don't forget Kerry in this picture. He's taken all the arrows of the first election and wont be running against W. Bush this time around. He also believes he is better than Hillary and will have backing from all the east coast liberals in a showdown. I think in the debates he will open up on Hillary and make her look stupid, of course that always gives a woman running the sympathy vote.
I'm sure he will help her, campaign for her, advise and all else, but he won't be her campaign manager.
They'll bring in some of the old pros, i.e. Carville, Begula, etc.
