I think he is. He's like Gore in the sense that he's had such a pampered and disconnected life that he's been able to just lie his way through the lower levels, but now that he's in the big leagues he doesn't know that he'll be outed. He may also be unable to separate fact from fiction when it comes to stuff that happened so long ago, or as you said, he "might be a skizo too boot!!"
"Disconnected" (mild) although I believe Kerry is a truly evil man bent on his place in history and writing it himself all the way. Fails so see how his actions in 1971 hurt thousands of people, failed to bring any closure to the families of the POW/MIA's and how he was ever appointed Chairman of the Senate Select Committee, since by his own admission he negotiated illegally with an enemy government, I will never know. Evil man!! No end to his boldness and treachery.
