Accidental presidents, those who assume office as a result of death, assassination or resignation, struggle to establish their legitimacy. This book examines and evaluates the strategies of nine accidental presidents, from John Tyler to Gerald Ford, to demonstrate authority and their capacity to govern.
A pretty quick summary of all of the "accidental presidents", I mean I read it in two and a half hours on the train, but it gives a very good summary of all of the presidents and how they tried to obtain legitimacy. It's a pretty good book.
