Sandy Berger walked out of a government office with classified documents stuffed in his pants. You would think that would have meant total ruin for him, but he's still on the Kerry campaign!
Kerry's people spun it as "He was only an informal adviser" - not explaining the "informality" of a person who was set to give a major speech for Kerry at the DNC convention. Also spun was that it was a Republican leak - but that would have occured after the convention.
The press dutifully bought the "informal" line, the lines about "only copies" and such. It was a pre-convetion dump by his own people.
Interestingly, Kerry might not have known about the investigation that had been going on since 2003. Bill Clinton knew about it - what does it say if he didn't warn Kerry?
