One of the comments:
If they are among the same Obama voters he'll keep losing them. He can only deliver on deportations and he will not risk losing non-Obama white voters by hinting the social/economic well being of minorities is a priority on par with whites. The rest of Trump's agenda, possibly the only portion of the Republican platform that can persist at the federal level is more Reaganomics and the continuation of Endless War, neither of which has helped a majority of voters of any demographic background.
