From the E Ring to the Convention Floor: Retired Flag Officers and Presidential Elections [open pdf - 586KB]
From the Thesis Abstract: "Although the concept of an apolitical professional military has widespread acceptance, active and retired general and flag officers have been involved with presidential politics throughout US history, either running as candidates for office, or endorsing candidates for office. Many observers consider such partisan endorsements by retired flag officers problematic. They view this partisan advocacy as potentially upsetting US civil-military relations and opening debates surrounding the apolitical professional ethic and its applicability after retirement. This monograph argues that partisan political activity by retired general and flag officers (GOFOs) is inappropriate and is potentially detrimental to effective civil-military relations between civilian leaders and serving senior officers."
