Politically Ill

I have always suspected that the profession of world leader is the one with the highest percentage of the mentally ill. So therefore if a person is both mentally ill, has a twisted world view and is zealous and determined yet is unaware of their affliction, then perhaps they feel compelled to enter office so as to change the world so as to match their world view. Perhaps because they are broken, they perceive current circumstances as broken, and seek to break the world in order to match it with their broken vision. This would explain Sarah Palin.
