Have you heard the one about JFK? FDR? Nelson Rockefeller? For some reason, powerful people seem to lie seamy side up, out-of-doors, at around high noon. By which I mean to say: We are obsessed with the private lives of public men. We always have been–for at least the last few thousand years. We interrogate them; we investigate them; we label them; we slander them–though it isn't always clear to the interrogators, investigators, slanderers or labelers why we should care.
