The media coverage of Trump has been consistently catastrophist since January. Whenever there is an outrage, pundits talk as though it's the end of his presidency. This is too dire. So long as Trump has the right enemies, namely the mainstream media and PC culture, there is a sturdy floor to his political support. But he is slip-sliding toward a crisis of legitimacy. This is the significance of the dissolution of his business councils. It’s not unthinkable, should this trajectory continue, that a time could come when some Republican officeholders refuse to visit the White House.
