I had no idea that Barack Obama curses before public speaking. I think I know at whom he curses before going on stage. I was as shocked to read that as I would have been to hear that 1950s-'60s movie star and cinematic symbol of chastity and virtue Doris Day cursed before going before the cameras. But I doubt that she did so. Doris Day? Fuhgeddaboudit! Anyhow, here's an article about how the current Democratic and Republican presidential candidates prepare for debates. It contains tips and advice you might find useful if you're faced with delivering a speech or engaging in a debate. Enjoy the public speaking article.
