'If you like your health care plan, you will be able to keep your health care plan, period." The line comes from President Obama's recent address to the American Medical Association, but it could have come from virtually any public statement he's made about health care in the last two years. That is no accident. Polls show that Americans think their health care system has severe problems, enough to warrant a major change. But the same polls show that a large majority are happy with their current health care arrangements.
