AP is reporting that Arlen Spector his passed away according to his son Shanin:
Longtime GOP Senate moderate Arlen Specter dies
I respect Senator Spector for the lines he would not cross but at the same time disappointed in a number of episodes in his long career of public service, most prominently his handling of the Clarence Thomas hearing including his grilling of Anita Hill. Honestly I do think he was mostly of that old school that did what he felt was best for his state. In hindsight would rather have more Arlen Spectors as the loyal opposition than the treasonous crew in the GOP side of congress today.
