Let's be realistic. Duke is backing Trump because he wants to deport ILLEGALS. Duke would be happier if he could find a candidate who would put all blacks on boats and Send them to Liberia. When Trump says ILLEGALS, it means more than just Hispanics. All illegals.
Perhaps you are right, but
only perhaps, for Donald Trump is really obsessed with only one border, namely, the southern border to Mexico. He has made no sounds about the northern border to Canada nor has he said a word about the many seaports/airports on the East or West coast where many, many illegal aliens have their first point of entry in the United States. Many Latinos may be indeed among those who come through those seaports and airports, but practically
only Latinos come through the southern border - and far fewer of them since Obama assumed the Presidency in 2009, an uncomfortable fact that Conservatives continue to ignore.
So, by being so totally obsessed with the southern border and the southern border alone, it is painfully obvious exactly which group of people Trump is talking about. And the white supremacists out there have noticed this as well..
And that is the problem.
