This is in no way surprising, and it will be easy to get outraged, but where is the hope? Well by being so divisive, like all populists Trump will only carry support for so far. He has ensured that he cannot do compromise and has already through his own arrogance over the shutdown, made sure he has had no choice but to do what he finds most demeaning. Lose face!
Look at people like Nancy Pelosi, they know exactly how to play Trump. Make sure that a Presidential candidate in 2020 is prepared to tech out to the MidWest and listen to them, without copying Trump's techniques. Everyone has an Achilles heel, Trump is no exception. His bullying will eventually bring him down by people who are prepared to put any of their own prejudices to one side and reach out and listen to others without compromise
