Um, Bush = historical precedent for using speech devices. I wouldn't be surprised if clinton wore one too. your words dictate national policy, lead to wars, cost people lives. President's words are HUGE.
sorry, i think the teleprompter is silly too. But I also think I don't want my leader looking the fool for the world to see. If Bush needed one, that's cool. If Obama can't speak perfectly without one, I'd rather he use a cheat sheet than make up words, say things he doesn't mean, then spend his day making apologies.
