They hate her for the same reason that the first mate hated Billy Budd, for the same reason that vampires find the cross so repugnant, for the same reason that the majority leader hates Senator McCain, for the same reason that Joe Biden hated Robert Bork and Clarence Thomas.
Becasue of all the things the author indicates, Sarah Palin is going to shake the Democratic leftist-liberal house to its foundation, and then bring it down...in fact, she's already doing so.
She, her family, their faith, their values, and their story represent the absolute refutation of all the tired old liberal mantras and victimology that they malignantly use to mentally, psychologically, and financially enslave whole classes of people.
From women's rights, to family values, to gun rights, to abortion, to energy policy, to taxation, to envrionmentalism, to fundamental governing principal, to U.S. soveriegnty and independence, and on and on...she is a wrecking ball to the leftist, liberal, socialist house.
