I think that Trump's so-called "outreach" to African-Americans is mostly a dog-whistle message to the white people to whom he gave the speech(es) in white suburbs: "Look, the Democratic policies, even under black President Obama, help no one, not even their black 'favorites.' On the other hand, MY policies (whatever they are) will help everyone on the plantation, starting with you white 'planters,' of course. Then there will be trickle-down (for the, er, black 'workers'). Make the plantations great again! What have you got to lose?"
(Truthfully, I don't have any idea whether DJT is sufficiently self-aware to actually conceive such a weaselly plan: but I DO think that it--the "black outreach"--will have the effect I described and be thus understood by his white votaries, just as it will be derided and despised by African-Americans who will easily see through its pretense.)
