Arlen Specter is a good one to listen to, because he has a lot of clout--However, as a former Philadelphian, let me assure you, Arlen is not a conservative--he is a liberal, at least by the Republican definition--he was also a "go for blood" prosecutor, and, given that he is no friend of either Rove or Ashcroft, would probably like nothing better than to chair a senate investigation himself--
