Campaigning to build the widest possible consensus for reform of the nation’s health care system, Barack Obama told the delegates of the American Medical Association that he wants their support, too. Persuasive and always polite, the president did not mention the embarrassing truth about his hosts—namely, that the A.M.A. has undermined universal care with mindless zeal for more than 70 years. The real question is not what the A.M.A. will support or whether the attitudes of the A.M.A. have changed, but why anyone would still heed its policy prescriptions. Very few national organizations have been so wrong for so long about the matters most salient to its own members.
