Well, if I end up having to pick between the small man in search of a balcony and Nixon in a pant-suit, I'd go for Colbert myself. So, it seems, does everyone younger then me:

In the match-up with Giuliani and Clinton, Colbert draws 28% of likely voters aged 18-29. He draws 31% of that cohort when his foes are Thompson and Clinton. In both match-ups, Colbert has more support with young voters than the GOP candidate.
