White people and men have always been represented on the Supreme Court out of proportion to their portion of the American population.

If Biden keeps his pledge and nominates a black woman, and if she is confirmed, then, for the first time, the percentage of black people on the Court (22.2%) will exceed the percentage in the population (12.1%).

Women will still be underrepresented in proportion to the population — 44.4%, instead of 50.5%.

Does 22.2% seem like too much representation for black people on the Court? Consider that there has never been even one Asian American or a Native American nominated to the Supreme Court. But also consider that many people believe that Clarence Thomas, because he is conservative, doesn't represent black people at all. 

Look how clearly Thurgood Marshall stated that position as he vacated the seat Thomas took (scroll to 2:30):

"Oh? I'd forgotten that he'd pledged to choose a black woman. Isn't that inconsistent with his 3 reasons for not giving us a list?"

"There can't be that many potential choices if he's got the type of person narrowed down like that. Who are the under-60 black female federal judges appointed by Democratic Presidents? Won't they all be influenced in their decisions — reason #1, [below] — even though their names are not on a list? Aren't they all just as vulnerable to 'unrelenting political attacks' as the individuals on Trump's list (reason #2)? And are you not violating reason #3 by making this pledge? You are trying to gain favor in a partisan election campaign, and when it's over, you'll be locked into that limitation and not able to make the sober, nonpolitical analysis you want us to think you will make. And isn't your pledge to appoint a black woman — just a black woman, not the person with the greatest skill and integrity — more political than Trump's list of real people, whose skill and integrity we can investigate?"

I blogged on September 20, 2020, after Biden gave 3 reasons why he would not, like Trump, give voters a list from which he'd choose his Supreme Court nominees.

The 3 reasons were:

1. "[P]utting a judge’s name on a list like that could influence that person’s decision making as a judge, and that would be wrong, or at least create the perception that it would have influence."

2. "[A]nyone put on a list like that under these circumstances will be subject to unrelenting political attacks."

3. "[I]f I win, I’ll make my choice for the Supreme Court not based on a partisan election campaign, but on what prior presidents have done.... [A]fter consulting Democrats and Republicans in the United States Senate and seeking their advice and asking for the consent... ... I’ll consult with senators in both parties about that pick, as well as the legal and civil leaders in our country...."
