Dr. Charles Krauthammer, at Hillsdale College's Constitution Day conference in Washington, D.C., explains why the American government system is unique in the world. Sure, there are other nations with constitutions, but only in the U.S. do the people so revere theirs. Since the advent of the Progressive Era at the dawn of the 20^th century, the U.S. government has consistently been straining against the constraints placed upon it. Let 2012 be the year we begin to reclaim our heritage of liberty by reasserting the authority of the Constitution.
