Well, let's face it - there aren't that many Democratic lawmakers who are also retired flag officers, so he'd have to be on the list. This is the "trial balloon" stage of things. People in the administration slip stories like this to the media to see what kind of response they get.
I agree w/ Flash. The fact that he was fired by the current Chairman doesn't bode well for Rep Sestak's chances, given that the President-Elect is making a big show of listening to his uniformed advisors.
I know some friends of the family who worked for him...suffice to say, he's not anyone's dream boss.
