“Whenever somebody says that an argument is settled, you can be sure that it is not. If it were settled, there would be no need to say so. No president will hold a press conference to announce that the argument over the prohibition of alcohol is settled, precisely because it truly is settled. So when President Obama declared the debate over his health-care law “settled” and “over,” as he did at an April 17 press conference, his performance was self-refuting.”
