As of now, I don't think it ends in either.  I don't expect HRC to offer it to Obama right now.  I also don't expect Obama to offer it to HRC.  Only way that happens is if both sides are forced by the Supers, and I'm not sure they'll do that.  Who knows.

Personally, I think Obama needs someone that's either

a) strong on foreign policy and the military to cover for his weakness there in a GE

or

b)  Someone who can sell an economic plan to the blue collar folks

As for HRC, she needs someone younger and viewed as with passion.  Also someone that's solidly to her left.  Edwards makes a lot of sense here for her.  Edwards makes sense for Obama as well.
