On CNN moments ago, Rep. Joe Sestak (D-PA) reiterated a couple themes he touched on when I interviewed him last night--specifically that the Democratic establishment has embraced Sen. Arlen Specter (D-PA) for expediency's sake, and that Specter may not be a reliable choice for Pennsylvania Democrats, particularly given that his next term, should he win re-election, won't end until 2016.

Specter's working toward a compromise with Sen. Tom Harkin (D-IA), chief sponsor of the Employee Free Choice Act, but Sestak's demanded much more of him if he hopes to fend off a primary challenge.
