CHARLES KRAUTHAMMER: It is not going to happen. It is absolutely not going to happen. Obama is invested in this, it's his signature achievement. For Democrats, it's an historic achievement. It's their road to national health care. It passed the House. It passed the Senate. Signed by the president and Supreme Court upheld the constitutionality. They are not going to give it up. What might happen, what might happen is that it could be such a catastrophe, so many Americans could be hurt by it and then begin to really strongly oppose it. Right now they're opposing the idea of Obamacare, but not so much the reality. It could collapse on its own.
