Yes, all true. But I also think there are much smarter people (with money) who are also promoting Trump--the oligarchs of this country--and they have an unearned and disproportionate amount of power in our current system, largely because they own a good part of our Supreme Court.
I don't think we'll change the minds of the cult members no matter what we do. But they are in the minority and have little power. It's the Harlan Crowe's and Leonard Leo's of the world we need to take on to prevent a Trump win--and the Republicans in Congress who pretend not to know what a loser Trump is.
