John Steele Gordon:

Not only does the liberal paradigm not even come close to agreeing with the social and economic reality on the ground today, worse, it has largely congealed into a political religion, especially in the nearly 30 years since Ronald Reagan shifted the nation's political center of gravity, just as FDR had done 48 years earlier. Since liberals care about the sheep, all who disagree with liberalism must not, making them morally inferior if not downright immoral. Thus the nastiness in American politics is largely on the left. Whatever you think of Sarah Palin, her treatment in the liberal press was ugliness personified.
