So, my theory (grab your TF hat): Hitlery had the documents made up and leaked to the Kerry campaign (knowing that 60 Minutes had been working on the story for four years and must by now be desperate for documents to substansiate their premise that Bush cheated or whatever). Carville et.al. were there to agrue for giving the the documents to CBS. The rest is history. The last step will be to leak proof that the Kerry campaign supplied the documents to CBS.
Would agree they are pretty hokey, but your comment has one big flaw: CBS fell for it. They were obviously good enough forgeries to trick CBS, so they weren't so bad that it had to be a plant.
Carville will leak the source that in a few weeks, say mid October.
We're having way TOO MUCH FUN!
