Eh, let it happen. If people laugh or angrily vote Colbert out of the race, that might indicate a passion for political issues that's higher than previous years. I would say it doesn't hurt to have informed people, but I don't know whether the other people are indeed informed. There's surely good arguments for and against any candidate. I just hope the good arguments win out. Even though I can't speak for how effective that'll be in picking a president who will do the things we elected him/her for.
While I severely doubt Colbert will be president (or even see him on the ballot), I think it'd be hilarious if it did happen. Maybe I think he'd be more honest than the other candidates.
