I've been struggling to figure out why Hillary remains in the race when it is virtually impossible for her to overtake Obama in elected delegates or popular vote. The only option I could come up with is she's staying in on the chance that some revelation (eg proof that he snorted cocaine off a dead hooker's body in Pittsburgh friday night) completely destroys Obama's campaign. This theory
makes some sense, too.
It's also possible that she's become Apollo Creed, pre-beach hug with Rocky, of course.
