No president, regardless of party affiliation nor the Lord himself can stop sorry ass white people from hating on blacks or people of color. And just the assumption that Obama could somehow convince rednecks that racism isn't cool, is ridiculous. Just as blaming Trump for racism, that too is stupid. Bottom line is this, until the dirt hits the box, white people will always harvest fears of being number two someday, harvest resentment of black men taking over their covenant barbies and will always need somebody to blame when life hands them a bad card and things don't go their way....its in the DNA of that race that has had privilege since the dawn of man.
