Why are libertarians afraid of Santorum?

David Boaz, executive vice president of the Cato Institute: Being philosophically minded, what scares me most about Rick Santorum is not his specific policy mistakes but his fundamental objection to the American idea of freedom. He criticizes the pursuit of happiness! He says, “This is the mantra of the left: I have a right to do what I want to do” and “We have a whole culture that is focused on immediate gratification and the pursuit of happiness . . . and it is harming America.” And then he says that what the Founders meant by happiness was “to do the morally right thing.” He really doesn’t like the idea of America as a free society, where adults make their own decisions and sometimes make choices that Santorum disapproves. In practice, I worry that he would continue and intensify Bush’s big-government conservatism, a federal government committed to reshaping individuals according to a religious-conservative blueprint.
