Are you a sports fan, Nick? Ever noticed how bad teams seem to fight amongst themselves, and winning teams always seem to get along?

Its in our nature as people to want to blame someone for failure. I'm sure that in the face of a possible historic landslide, Sarah Palin is terrified that she's going to be blamed, and her political career is about to come to an end. Likewise, I'm certain that John McCain isn't exactly looking to shoulder the blame for their embarassment of a campaign either. So they fight.

Basic human nature.
