Abstract
One concern with allowing governors to appoint replacements for U.S. Senate vacancies is that appointees may have an advantage over their competition in seeking election. Another is that governors may use their power to further their own political ambitions. This investigation explores whether an electoral benefit is conferred through receiving or making an appointment. The analysis provides insight into how gubernatorial appointments shape electoral outcomes for quasi-incumbents and the Senate's membership. Notably, the results reveal an electoral boost for representatives who are appointed prior to making a run for the Senate. Although the results demonstrate that some appointees gain an advantage by receiving appointments, governors who run for Senate do not experience an electoral benefit from making an appointment.
