"One of the commonly stated virtues of modern constitutional democracies is their capacity to insure reliable and accepted methods of political succession through election. This book focuses on one complication in the democratic mode of political succession: American vice-presidents who assume office as a result of the death, assassination or resignation of a president. Three basic strategies by "accidental presidents" to establish and enhance their legitimacy are identified and evaluated. While none are reliably successful, each provides a lens to study the nature of presidential power and authority as well as to contribute to a democratic theory of succession."--BOOK JACKET.
