The contemporary presidency, and the nation it governs, is more dependent on the individual in office than ever before. The Progression of the American Presidency examines in detail the institution of the American presidency from the selection process, to the president's individual responsibilities, to his interactions with other actors in the political arena. Twombly argues that regardless of how well suited a particular individual may be for a specific time in office, he or she will leave an indelible imprint on the office for those who follow. Each successful president changed the institution in which he served by expanding its scope and power and raising the bar of public (and historical) expectations. Both scholarly and conversational, The Progression of the American Presidency is essential reading for anyone interested in the evolving state of the Oval Office.
