Hegel remarks somewhere that all great world-historic facts and personages appear, so to speak, twice. He forgot to add: the first time as tragedy, the second time as farce.
— Karl Marx

Though no precedent tragedy comes to mind. I think there are elements of both tragedy and farce in these first months of Trump's term.
The presidency has been described as a weak office, having great power only in foreign affairs and employment of the armed forces abroad. So it's not king for a day or CEO of a business corporation. Politics is called the art of the possible. Two masters were Lincoln and Franklin Roosevelt. Both got things done.
Trump will continue to do what he can with executive orders. He may learn more about practical politics. I hope so, as that often involves compromise.
