“Trump is wasting time and energy”
Probably. But he can still cut into the minority support. If he can pull in 15% of the black vote and 35% of the Hispanic vote, it will hurt Hillary.
I doubt it
Come election day the black vote will be 99% democrat as usual
Only thing that can help the culture is internal change which at this point is probably impossible
No government OUTREACH ( whatever that means )is going to work
