I see Sarah Palin as Kiwanis Club winner of the Miss Wassilaa Beauty contest whose entire career is driven by skin deep impressions and perky deliveries of memorized sound bites.

She has managed to violate the Peter Principle several times over due to the small sample size of her competition in Alaska.
If she is homestly typical of the best Evangelicals have to offer, then the Peter Principle is obviously subject the the theory of Relativity.
