The hands are too dominating to have been a default position. But I think you have to look at the Gestalt here. This is a very bizarre presidential portrait... unless you plug in the fact of the president's serial predation of women.
This picture was taken at the end of his presidency. Perhaps, this was the photographer's comment on that, as well.
As historian Douglas Brinkley said of the clinton presidency when refuting clinton's Hofstra-apologia lie that he, Brinkley thought clinton would have been a great president but for impeachment--(Brinkley actually RUSHED to HNN to set the record straight): [It] will be "hard to get people queuing up a hundred years from now excited to see the "NAFTA Pen Under Glass."
But perhaps Brinkley is missing what apparently did not elude the Esquire photographer: clinton will be saved from oblivion by the magnitude and consequences of his evil.
