A few nights ago in the historic Renaissance Grand Hotel in St. Louis, Mo., President Obama reassured a crowd of Senator Claire McCaskill supporters that health-care reform wouldn't just be good for their health, it would be good for the health of the country: "I said at the beginning of this thing we would not do anything that adds to our deficit," he said to the clapping audience. "This plan does not do anything to add to this deficit. And that's how we should be operating."
