Trump over the next four years will need somehow to make the American people understand that the Democratic Party has devolved into a globalist, socialist, anti capitalist and anti individual freedom entity. They are much more a vanguard of the EU than a distinctly American political party. Open borders, unrestricted migration is the de facto Democratic policy. There is no such thing as an “illegal alien” or an “illegal voter”.
I think a lot of people are clear on that, especially Bernie supporters, but they didn't see Trump as the answer. But he has four years to win over people who couldn't see it the first time, and so far he is doing well. His work getting Carrier to keep jobs is being noticed. If he keeps it up, by 202 the Republicans will solidly be the party of the blue collar working class, and the democrats will be seen by everyone as the party of elite snobs.
