In 1973, historian Arthur M. Schlesinger Jr., published a book entitled The Imperial Presidency.1 This was a time of one of the worst political crises in American history. A prolonged and increasingly unpopular war in Southeast Asia was tearing the nation apart, and the Watergate scandal was about to reach its climax. The American public was not only shocked by revelations about the actual Watergate break-in and the attempts to cover it up, but also by the assumptions about executive power that had seemingly guided the president and his advisors.
