You know why? Cause it is like being a school bus driver to some mega huge bus the size of the Titanic, driving down the tiny, pot-hole ridden, muddy, cliff strewn roads of Colombia. Picture it, trying to keep that bastard on the small road, while there are bratty children yelling at you from all across the spectrum of opinions about your job. All telling you that you are doing a piss-poor job no matter what you do.
Why would anyone want that job? Well, you do get driven around in a limo like a rock star. And you do get paid pretty well. Then there's the power, everyone loves power, especially the ladies according to former-President Clinton.
But according to former-President George W. Bush what really makes it worth it are the "yes" men. Those lovable scoundrels who will tell you that "yes" you are doing a great job when you are actually driving that bus over the cliff and down a river to a waterfall the size of Niagara Falls. Maybe you should have listened to some of those bratty kids when they were warning you that the bus was filling with water. But no, you listen to the "yes" men and everything will be ok...
