The premise behind this book is that policy making provides a useful perspective for studying the presidency, perhaps the most important and least understood policy-making institution in the United States. The eleven essays focus on diverse aspects of presidential policy making, providing insights on the presidency and its relationship to other policy-making actors and institutions. Major topics addressed include the environment of presidential policy making and the constraints it places on the chief executive; relationships with those outside the executive branch that are central to presidential policy making; attempts to lead the public and Congress; presidential decision making; and administration or implementation of policies in the executive branch, a topic that has received limited attention in the literature on the presidency.
