With friends like Arlen Specter...
Lots of Eisenhower democrats out there, evidently. I notice from the byplay at Specter's press conference that he's claiming to have greater seniority (as a turncoat pretending to be a Democrat first elected to the Senate in 1980) than Tom Harkin (a well and proper true blue Democrat first elected to the Senate in 1984).
Also, please note that Specter's first act as a Democrat was to oppose Dawn Johnsen, President Obama's nominee to head the Office of Legal Counsel. Not to mention promising to vote with Republicans on cloture sometimes, if not most of the time — aginnit, i.e.
Specter would probably be more comfortable as an "Independent" with Joe Lieberman in an AIPAC phone booth.
