Just found this wherre Jerry Springer says it's a mistake for liberals (Although I think he means Leftists) to attack Palin. The Reader's Digest version is that when they mock Palin, they mock people like her, and there are twice as many people like her as there are Leftists.
Sitting in their comfortable echo chamber where they only talk to like minded souls, they miss the fact that the rest of the country is not like them. Oh sure, they look with disdain on those they want to help (Think "What's the Matter with Kansas?) even if they don't want the help.
But keep it up. As a minority, your ability to piss off the rest of us is much greater than your numbers would be expected to.
