I’m equally certain it will be neither, and here’s why: Biden made a specific point to state right at the point of his big reveal that he will appoint a black female to the SCOTUS if he gets the chance. He made this clear so when he picks a white female running mate, the black women in the Democratic caucus, who are the backbone of the party, understand he fully recognizes their importance – but it won’t be with a VP pick.
Smart.
