Apparently Lieberman wasn't all that impressed by Dean's "primal scream," so he ridiculed him in the press...But WHO DIDN'T??
That was about the extent of detail given, but I didn't want to bury and embarrass the kid in front of his folks.
Wasn't Lieberman still in the race at that point? I can't believe Lieberman was the only Dem who was running that criticized Dean for that loony scream.
