This is a revision and an updating of the first edition, published in 2000. Presidents from Washington to Obama (not included are William Henry Harrison and James A. Garfield because of very short terms) are rated in five categories: Foreign Relations, Domestic Programs, Administration and Intergovernmental Relations, Leadership and Decision Making, and Presidential Comportment.

Each president is evaluated on his effectiveness in each area and a final analysis is provided for the scores combined. The presidents are then ranked overall. The most overrated and underrated chief executives are identified. Each entry includes biographical and political information, as well as an analysis of their overall behavior and status.
