This classic text on the American presidency analyzes the institution and the presidents who hold the office through the key lens of leadership. Edwards, Mayer, and Wayne explain the leadership dilemma presidents face and their institutional, political, and personal capacities to meet it. Two models of presidential leadership help us understand the institution: one in which a strong president dominates the political environment as a director of change, and another in which the president performs a more limited role as facilitator of change. Each model provides an insightful perspectives to better understand leadership in the modern presidency and to evaluate the performance of individual presidents. With no simple formula for presidential success, and no partisan perspective driving the analysis, the authors help us understand that presidents and citizens alike must understand the nature of presidential leadership in a pluralistic system in which separate institutions share powers. This fully revised thirteenth edition is fully updated through the Biden administration, with recent policy developments, the 2022 midterm elections, changes to the media environment, and the latest data.
