We don't just want lower taxes, we also want meaningful immigration reform, reduced interventionism abroad and to at least maintain the conservative/liberal split on the supreme court among many other things. Trump does a lot wrong, especially in how he presents himself to the world, but for people to sit at their computers and pretend he has accomplished nothing is hilarious. It's the same kind of make-believe fantasy land everyone was living in up to the night of the election.
I have no clue what will happen in 2020, but I hope people make a better attempt to confront some type of objective take on reality than they did in 2016. People who want those things are not neo-nazi racists, they're just regular every-day type of people and any given person probably knows quite a few.
