The USA is already a de facto tyranny, with the Republican Party destroying all semblance of legal norms and the five Republican judges on the Supreme Court always supporting the Trump administration regardless of merit. Trump is merely an infantile moron, but a much more intelligent and more self-controlled man has understood the lesson Trump has accidentally taught: that absolute power is easy to seize in the USA. That man will be the USA’s last elected President, at some point in the next 12 years. So the 2020 election is irrelevant; the end has already been determined by the enthusiasm and haste with which GoP politicians obsequiously and in servile fashion embraced tyranny merely in order to cling on to the illusion of power.
