Casey Endorses Obama

Another wine-sipping elitist gets on the Obama bandwagon, in the person of Bob Casey, Jr.

This highlights what is, perhaps, the ultimate madness of the Clinton superdelegate strategy -- all the superdelegate momentum is against her. She built up a huge lead months and months ago back when she was "inevitable" and has monotonically lost ground since then. And yet the whole premise of her campaign is that there's a secret wellspring of Clinton support among undeclared supers who are just dying to overturn the results of the primaries and give her the nomination.
