The Democrats need to stop fetishizing conservative white working class people. How many times are these fundamentally right-wing voters gonna snatch the football away before the left learns their lesson?
The problem with the democrats right now is that forming a coalition of minorities and college educated whites isn't feasible. They have to broaden their base somehow.
They'd have to improve their margins with college educated Whites (a group that Trump won, lest we forget) by a LOT if they want to win, though. Let's not act like college Whites are the bedrock of the Democratic Party, they literally voted more Republican than Democrat.
I agree, I do not think that the future of the Democratic Party will be forming a union between minorities and college whites.
Working class whites and minorities would be a more feasible coalition to create. In fact I'm deeply worried that democrats will lose in 2020 by trying to target college whites over working class whites and having that strategy blow up in their face.
