Observing substantial variations in Senate confirmation durations, existing studies have tried to explain when the Senate takes more or less time to confirm presidential nominees. However, they have largely ignored the president’s incentives to nominate someone who he expects will be delayed and do not specify conditions under which delay occurs. To improve on existing literature, I develop a dynamic model of presidential appointments in which the Senate decides whether to delay as well as whether to confirm the nominee. The model shows that the president rationally chooses a nominee who he expects the Senate will delay if the status quo belongs to a certain interval in a one-dimensional policy space. Moreover, the president sometimes chooses a nominee who may fail to gain confirmation after a delay. Finally, the effects of important factors on expected confirmation duration are analyzed: most interestingly, as presidential popularity increases, the Senate takes longer to confirm the nominee.
