Just to clear some things up:I can't speak for the black man sadly but that black women number is going to show itself to be fugazi as hell I believe. I think she's going to be at or near 90%.
Black women, the heart of the Democratic party, is not going to vote for the first black female candidate of the party? I got a bridge to sell you if think this is remotely true.
1) Bunchy Carter is a both sides Trump supporting idiot. He posted that image for nefarious purposes.
2) That image is comparing exit polls (which are faulty) to a single pre-election poll from Pew. Pre-election polls almost always underestimate Black voters support for Democrats.
