As a Canadian looking in to the shit hole of the USA, and unfortunately probably knowing more about the US Constitution and role of government than most Americans -the recent SCOTUS rulings are in fact a coup against the separation of powers - they only give a President immunity to what 'they' will allow, and that will be arbitrary and pernicious depending on their warped sense of loyalty and power
This is exactly what the Nazi Party did when Hitler became Chancellor - own the courts
