Although historians seem to malign Warren Harding, I think he was one of our better presidents. Not only was he the only president of the twentieth century to significantly reduce the size and scope of government, but he held the belief, now regarded as rather quaint, that the president should serve as the chief magistrate of a constitutional republic rather than as an elected king.
