No person selected and approved as Supreme Court Justice in my life time, if ever, was selected based on their qualifications. Qualifications are a given based on vast number of experienced candidates who have proven themselves in court. Each person is selected based on ideological and cultural preferences. Biden stating his nominee will be a black woman is no different than Trump pledging to select from the Federalist Society’s conservative pro business, anti abortion list. This is the way it is always done.
