The question here is why? Why do Sarah's enemies keep rehashing the same tiresome trash if Sarah is indeed a weak candidate? Why would anyone in their right mind give so much attention to such a weak, unimportant individual?
The answer is because Sarah is far better than what they chose to depict. In fact, Sarah threatens their pitiful political lives and shakes up their status quo. She is very popular with the base while McCain isn't, and the reason for her popularity is based on the fact that she is a strong, genuine conservative - and they truly hate that.
You make good points. How nice it is that "working America" are "redneck trailer trash, ignorant" to these citified sophisticated chi-chi people.
When it comes down to survival though, they will never make it, whereas we "trash" people know how to shoot and grow our food, preserve/can/store it, protect our own and keep warm. They don't just hate Sarah. They hate US!
