I think we all agree that you don’t like Trump’s style.
He says a lot things that rub you the wrong way - things like “at some point, you’ve made enough money” or “you didn’t build that”, “if you like your doctor, you can keep your doctor”, “we want to bankrupt the coal industry”, " we want to make electricity very expensive". “Americans cannot go on keeping their thermostats at 72” , “I don’t speak Austrian”, etc.
As I said before, when he actually implements or proposes an unconstitutional law, or a policy that violates the spirit of the Declaration, or some abuse of the FBI or CIA, like spying on the American press, or using the IRS to persecute political enemies, or using energy policy to enrich favored companies, or when he lies to the public about the reason an American ambassador was murdered in a foreign land, or when he receives vast sums of money from foreign governments via a private foundation set up by his wife, or if he runs all his email through private servers so none of his doings are tracked or stored according to government regulations and sunshine laws, I’ll share your concern. Maybe, 'cause I’m sure I left out many things in that list.
By the way, there is no doubt that he will do some of the above, indeed, has already done so, just as every president has before him, to a greater or lesser degree, many of them like Obama, no doubt much worse.
Right now, you’ve got nothing but world opinion polls (that would have rated Ronald Reagan the worst ever president as well), opinions from the New York Times (ditto about Reagan), and your own hysteria (worst president in 200 years!), which, as entertainingly explained by Scott Adams, you probably cannot see or understand.
