Cleland may well be the source.
Think about it - Burkett is damaged goods. Even liberal Rags like the Boston Globe said he was discredited and not to be believed.
Max Cleland, on other hand, may well be Danny's "unimpeachable source."
I could be wrong, but Max Cleland has yet to deny this allegation. Therefore, we can assume he is indeed the culprit.
The next question is will Burkett squeal like a stuck pig.
And will Cleland take one for the team.
With his visible hatred for Bush, I can connect that dot.
