Were I debating him on TV, I'd intentionally start pushing his buttons. Not only does Dean lack the charm and savvy to avoid the trap, but he'd come across as creepy and unhinged.
Can you imagine President Dean with nuclear weapons? I think the briefing would go something like this...
Briefing Officer - "As you know, sir, this man has the nuclear launch codes in his suitcase. Every morning the codes are scrambled, and he cannot unscramble them until he sees you take your meds."
Dean - *SNARL, SNARL*
Beiefing Officer - "Correct, sir. He has to see you take them in person. And no hiding them under your tongue like last time"
