Don't be too sure about Burkett holding info back after they burn him, he's a well documented, A-1, whack job who holds a big grudge. So in that regard we still got hope.
True, true, and he does have a strong streak of paranoia, so he could come to see a lot of his liberal friends as part of "the enemy" if they throw him to the wolves.
Still, even if he goes nuclear I think he'd concentrate on hurting CBS and not on hurting Kerry.... but who knows, he certainly is a loose cannon.
