Is this a great country or what? Not because the Court upheld the overall scheme of the president's health care law. That is an ordinary question, no matter how much money was at stake. It is a great country because the workings of our carefully wrought system of government are not predicated on punditry, predictions or polls. Defying the expectations, Chief Justice John Roberts joined the court's liberal wing in saving the law by grounding the individual mandate not in the power of Congress to regulate commerce, but in its taxing power. As I suggested yesterday, the court essentially said that Congress could not require people to buy something in the private economy, but they could fine them if they didn't. The court found that power to fine, in the taxing power of Article I. Now the president will have to figure out a way to make the fines in the law -- which are weak and toothless -- real.
