Rep. Joe Sestak (D-Pa.) sought to portray himself as the real Democrat in the Senate primary against Sen. Arlen Specter (D-Pa.).

During the course of the campaign, he pointed to Specter's past in the GOP and played up in a TV ad the praise the former Republican received from George W. Bush. But is Sestak a team player? And do you need to be a team player to be a good Democrat? The Philadelphia Inquirer thinks so.

In reiterating its endorsement of Specter, the Inquirer's editorial board made this point:

Sestak has taken the rash step of giving up his 7th District congressional seat after only two terms to take advantage of Specter's vulnerability. Sestak accuses Specter of putting personal interests first. But Sestak's decision to give up his seat makes it likely that a Republican, former U.S. Attorney Pat Meehan, will win it.

That certainly won't be good for President Obama's agenda.
