Every one of the revelations that have come out so far would be impeachable. Every single one. The affair would have been characterized as a coup de etat, as a subversion of the Constitution and of the Bill of Rights, as a historical attempt to subvert the traditional peaceful process of succession that has kept out country safe from violent revolution for more than 150 years.
There would be massive demonstrations in Washington DC and other large cities around the country, and around the world. There would be demonstrations in London, in Germany, in the Scandinavian countries.
There would have been multiple television specials, and probably one or two Hollywood movies about the gigantic, burgeoning scandal already produced. We would have gotten to know every single person who had been surveilled, who had had their privacy destroyed. There would have been allegations that teenage sons and daughters had their private lives invaded. There would have been stories about how PDJT and his staffers sat around laughing at the private secrets that were being reported to them by audio and video means.
The President would have been denounced by BOTH parties, in BOTH houses of Congress.
Every comedian in the country would have made the entire gross, indecent outrage the center of their act.
Retired Republican and Democrat politicians would have been interviewed and would have expressed their outrage.
I’ve thought about the reverse. Whatever it is that they end up being known to have gotten away with, Trump should do exactly the same in 2020.
