The president serves dual roles in the political system: one who “commands” by pursuing his or her agenda using unilateral orders and one who “administers” and who works to continue proper government function, often with the support of Congress. In a reassessment of the literature on unilateral power, this book considers the president’s dual roles during the stages of the policy-making process. Although presidents may appear to act “first and alone,” the reality is often much different. Presidents act in response to their own concerns, as well as assisting Congress on priorities and the need to maintain harmonic government function. The authors find support for both the model of an aggressive president who uses unilateral orders to push his or her agenda, head off unfavorable congressional legislation, and selectively implement legislation, and they find support for a unifying president who is willing to share management of government, support Congressional legislative efforts, and faithfully implement legislation. At the same time, presidents self-check their actions based on the ability of Congress to act to overturn their orders, through a shared sense of responsibility to keep government moving and out of respect for the constitutional balance. The shared nature of unilateral orders does not preclude an active president, as presidents remain strong, central actors in the political system.
