The Wahington Compost doesn't have buyers remorse IMO. The article is written by George Will, their pet token conservative.
I am betting that the ed board and the rest of the staff think this behavior is just great.
Granted WaPo wouldn't care if the devil were in the Senate as long as he caucused with the Democrats. And I understand WaPo is under contractual obligation to run Will's columns.
But WaPo's given this incident a fair amount of ink, including a very unflattering picture of Webb with the article yesterday, the kind of unflattering picture usually reserved only for Republicans.
I think WaPo may be thinking, "Couldn't we have found somebody who wasn't going to look like just another crazy, undisciplined liberal?"
