Now on the urban "minorities", I think what is going to happen is the Trump Train is going to be rolling hard through some hard hit metropolitan areas with infrastructure projects that pay well, with lots of favoritism for those who work, punishment for those who don't.
What it will do is focus on those smaller percentages of the nonwhites who were still pro-Trump for social and economic reasons, and he is simply going to favor the working class over what everyone calls the parasite class. That's going to give the working class a lot of clout, although it may not deliver the actual voting numbers in four years, I think it will keep those urban areas from turning into war zones.
