I wish I could say it had more direct ties to Kerry, but there really were no "brains" behind this. It was dumb from the beginning and the fact that it is unraveling so quickly causes me to think that it really was just the lone nut. If anything, I think he duped them rather than them using him.
Nah, it doesn't work that way in the world of big time journalism. Lone nuts are a dime a dozen, and folks like Rather can spot them in seconds. No, this is much bigger. The "unimpeachable source" is the one we're after.
