Since then the Democrats have enjoyed huge support from black voters. It's pretty typical to see the Democratic presidential candidate to get 85%+ support of black voters.

Trump tried to change that and actually tried to appeal to black voters, then screwed it up during one of the debates and has mostly abandoned his attempts since.
