"My gut feeling here is that Sestak is holding this alleged proffer of a job over the White House's head to try and make sure that the West Wing does everything it can to support his candidacy."

"That's bothersome, because it means that someone believes they can use an allegation to divert the attention and resources of the seat of government. I also think the White House, and Rahm, have plausible legal-political-practical defenses. Moreover, Sestak might have decided to overstate the terms of the proffer -- maybe Rahm just floated the idea -- to puff up the drama to the story. The admiral was known for being a savvy political player when he was on active duty."

A nasty mess.

ADDED: Blackfive quotes Sestak's pathetic stonewalling on "Meet the Press" and says:

[T]he fact that Joe Sestak -- even after being called a liar by Robert Gibbs -- has not come forward and made a statement to the authorities about felony corruption he claims to have witnessed says something about Joe Sestak.  And what it says is this:  Joe Sestak is either a coward, a liar, a political sycophant or -- and this is where I'd put my money -- all three of these things.
