“…Instead, extant research cites vacancies as unfortunate consequences of turnover in a large administrative bureaucracy (e.g., Chang, Lewis, and McCarty 2001), confirmation delays (e.g., Binder and Maltzman 2002;Madonna and Ostrander 2017;Ostrander 2016) that are prolonged by nominee ideologies (e.g., Bonica, Chen, and Johnson 2015;Chiou and Rothenberg 2014), periods with divided government (e.g., McCarty and Razaghian 1999), or presidential delays in nomination due to the vetting process (O'Connell 2009). Just a handful of studies explicitly considers how presidents contribute to the accumulation of vacancies (O'Connell 2009;Hollibaugh 2015;Hollibaugh and Rothenberg 2017;Resh et al 2020), with a notable exception being Hollibaugh (2015), who does explore sustained vacancies as a deliberate strategy within a president's larger nomination strategy space. However, more work still needs to be done, as Hollibaugh's theoretical model considers only the timing of nominations and does not set them within a larger bargaining game over Senate confirmation.…”
