Many historians and political scientists have attempted ranking or grading the the men who have held the nation's highest office. To do this, the reviewer must establish a standard against which to assess each presidency. It is difficult, however, to establish a reliable standard resulting in attempts which are fundamentally flawed. Frequently, the author's standard applies their personal view of presidential greatness as the measuring stick by which all presidents should be judged. This is a natural tendency, but fails as an objective measure.
Steve Hayward, in The Politically Incorrect Guide to the Presidents, selects perhaps the most reliable (and, sadly, too often forgotten) standard: the president's duty to, "preserve, protect, and defend the Constitution of the United States." In doing so, Hayward's work provides useful insight into each president's use -- or abuse -- of his powers as granted by the Constitution, while still accounting for the ways in which the domestic and foreign policy demands of the office have changed over the past century. Hayward's message is successfully communicated via prose which is informative without being lost in political science jargon.
A highly informative and entertaining (or, depending upon the reader, enraging) read. Recommended.
