“My Hispanic family is voting for Trump, they want a wall built preferable with land mines”.
I think we need to keep in mind this media portrayal of a monolithic Hispanic or Black or Muslim community is myth. If you are Hispanic watching illegal gangsters wrecking your community, and intimating your people from fighting back, you want someone to stop them. Trump sounds like the guy who is going to be ON your side in that case.
EXCEPT:
2008: Fully 96 percent of black voters supported Obama and constituted 13 percent of the electorate, a 2-percentage-point rise in their national turnout. As in past years, black women turned out at a higher rate than black men.
2012 Black vote: Obama 93%, Romney 6%; 1% Others. A little bit better than McCain ,but still VERY monolithic...
The good news is there is no way Hillary will get the same numbers. If Trump wins the nomination, a lot more Blacks will vote for him than have voted for a Republican in the past many elections.
