He is not actually trying to woo black voters, so lowering his estimation with that demographic is not a problem for him.
What is more disturbing to me is that this almost certainly won't lower his estimation in the minds of his white fans. I find it hard to imagine how they justify continued support in the face of this indifference to fairness, justice and rule of law.
How a person reconciles supporting that and still maintains any sense of personal integrity or honor is baffling to me.
