I believe it's because more people voted for Obama throughout the caucuses than they did for Clinton.

I could see there being an attempt for her to run "independent" of the main Democrat ticket.

she won't do that... she's far too classy to drag it out like that

I think Obama would have saved this election had he dropped out months ago, and kept the party united.

very true! He might have been more accepted as VP - but I don't know how it'll turn out now... may be moving to argentina

oh please. She isn't leading the ticket for the simple fact that more people voted for Obama.
