I suppose you mean "Render unto Caesar what is Caesar's". That meant, "Pay your taxes." Otherwise, there is no scripture demanding obedience to the President of the United States, or its first century equivalent. In Christianity, morals are not compromised because a powerful person demands it. That'w why Christian history is dotted with martyrs.

We are speaking of a different thing, incompetence, corruption, fraud, deceit. Obviously neither you nor many of Trump's voter cared that Trump was and is a womanizing playboy with no perceptible morals. The fact that someone else was, also, is no excuse whatsoever. Trump's voters were thoroughly hoodwinked, taken for a ride. If they can't see it by now, they are truly foolish.
