Did you also notice his hands shaking at times?
He has much of the sound and actions of early Parkinson's.
The funniest thing was when Sean asked RFKJr. if he was a Nader supporter or a Kerry supporter, because he sounded like a Nader supporter - and Kennedy started whining again about name-calling. That's name-calling?!?
Yes, you're right. I believe that there are the beginnings of a serious neurological disorder here. It could be Parkinson's or it could be "Parkinson's like symtoms" caused by something else.
His voice sounds like the creature from the movie THE FLY.
(the original with Vincent Price). He is more like the character REV JIM from TAXI. Better living through CHEMISTRY.
