I think we should all take notice that few folks stay very long in the Chief Of Staff job at the White House for any President and few even want that job. Imagine if you can, what that job description actually includes. You have to put up with and eliminate White House staff jealousies and in-fighting, preventing leaks to the press and keeping the screwballs and pains-in-the ass from insisting on protesting or seeing directly to the President, lobbyist, politicians with agendas and every other kind of kook who wants access. And you need to know Washington politics and how the swamp works and recommend to the President the best way to deal with Congress and his ratings and such. It's a 24-7-365 job without any glory. Who in swamp hell would want such a job?
