People in very high places suddenly fall, and we are always surprised because we don't factor in the basic element that they're humans and, therefore, they are flawed and have weaknesses.
As a politician, you have to deal with someone wanting you to fail every day. I think I prefer being in a situation where generally people are rooting for me, and if they aren't rooting for me, they aren't out there to see my downfall. I respect the people who have the stomach for it.
