The Who, When, and Where of Executive Nominations: Integrating Agency Independence and Appointee Ideology

In recent years, scholars have expended considerable efforts to understand the executive appointment process and the forces influencing the choices made by the president and the Senate. However, some factors integral to theoretical models have not been well integrated empirically, and other relevant factors have not been incorporated much at all. Here, we focus on one determinant corresponding to the former critique—nominee ideology—and another corresponding to the latter—the independence of decision makers in the targeted agencies. We examine a series of theoretically driven hypotheses regarding the effects of both ideology and independence on who gets nominated and if and when nominees are eventually confirmed. Results show nominee ideology and decision maker independence matter a great deal and factor into presidential strategic choices and senatorial responses in ways according to expectations. Our findings have important ramifications for understanding appointments empirically and for future theoretical development.
