Another senator backs Obama

By Creature

I don't believe Obama has a prayer of winning Pennsylvania (though if he did it would surely put an end to Clinton's campaign). His best hope is to pull within 10 points, or so. With that in mind, landing Pennsylvania Senator Bob Casey's endorsement today is very good news. Not to mention another superdelegate has jumped off the fence.

Let the Hillary "death watch" begin.
