Tweety Redux

Somewhere in the dawn of time (like, a day or two ago) we mentioned Christopher "Tweety" Matthews implying who knows what about poor old Arlen Specter.Howard Fineman & Joan Walsh explain that Specter got screwed (or let himself be screwed) which is why the Senator's wandering around in a daze. Tweety seems to think Arlen's just lost it. At this point, is it possible to care any less?
