Of 895 slots in the freshman class of Stuyvesant High in New York City, seven were offered this year to black students, down from 10 last year and 13 the year before.
In the freshman class of 803 at The Bronx High School of Science, 12 students are black, down from last year's 25.
Of 303 students admitted to Staten Island Technical High School, one is African-American.
According to The New York Times, similar patterns of admission apply at the other five most elite high schools in the city.
Whites and Asians are 30 percent of middle school students, but 83 percent of the freshman at Bronx High School of Science, 88 percent at Staten Island Technical and 90 percent at Stuyvesant.
What do these numbers tell us?
They reveal the racial composition of the cohort of scientists and technicians who will lead America in the 21st century. And they tell us which races will not be well represented in that vanguard.
They identify a fault line that runs through the Democratic Party, separating leftists who believe in equality of results for all races and ethnic groups, and those who believe in a meritocracy.
Mayor Bill de Blasio has expressed anger and frustration at the under-representation of blacks and Hispanics in the elite schools. But Gov. Andrew Cuomo and the state legislature have ignored his pleas to change the way students are admitted.
Currently, the same test, of English and math, is given to middle school applicants. And admission to the elite eight is offered to those who get the highest scores.
Moreover, Asians, not whites, are predominant.
Though 15 percent of all middle school students, Asians make up two-thirds of the student body at Stuyvesant, with 80 times as many slots as their African-American classmates.
The egalitarian wing of the Democratic Party sees this as inherently unjust. And what gives this issue national import are these factors:
First, the recent scandal where rich parents paid huge bribes to criminal consultants to get their kids into elite colleges, by falsifying records of athletic achievement and cheating on Scholastic Aptitude Tests, has caused a wave of populist resentment.
Second, Harvard is being sued for systemic reverse racism, as black and Hispanic students are admitted with test scores hundreds of points below those that would disqualify Asians and whites.
Third, Joe Biden has a history on compulsory integration dating back to the 1970s that Sen. Jesse Helms called "enlightened."
Here are Biden's quotes, unearthed by The Washington Post, that reflect his beliefs about forced busing for racial balance in public schools:
"The new integration plans being offered are really just quota systems to assure a certain number of blacks, Chicanos, or whatever in each school. That, to me, is the most racist concept you can come up with.
"What it says is, 'In order for your child with curly black hair, brown eyes, and dark skin to be able to learn anything, he needs to sit next to my blond-haired, blue-eyed son.' That's racist!
"Who the hell do we think we are, that the only way a black man or woman can learn is if they rub shoulders with my white child?
"I am philosophically opposed to quota systems. They insure mediocrity."
That was 44 years ago. While those views were the thinking of many Democrats, and perhaps of most Americans, in the mid-'70s, they will be problematic in the 2020 primaries, where African-Americans could be decisive in the contests that follow Iowa and New Hampshire.
Biden knows that just as Bernie Sanders, another white male, fell short in crucial South Carolina because of a lack of support among black voters, he, too, has a problem with that most loyal element in the Democratic coalition.
In 1991, Biden failed to rise to the defense of Anita Hill when she charged future Justice Clarence Thomas with sexual harassment. In the Senate Judiciary Committee, he was a law-and-order champion responsible for tough anti-crime legislation that is now regarded as discriminatory.
And he has a record on busing for racial balance that made him a de facto ally of Louise Day Hicks of the Boston busing case fame.
How, with a record like this, does Biden inoculate himself against attacks by rival candidates, especially candidates of color, in his run for the nomination?
One way would be to signal to his party that he has grown, he has changed, and his 2020 running mate will be a person of color. Perhaps he'll run with a woman of color such as Stacey Abrams, who narrowly lost the 2018 governor's race in Georgia.
An ancillary benefit would be that Abrams on the ticket would help him carry Georgia, a state Donald Trump probably cannot lose and win re-election.
Wrote Axios this morning:
"Close advisers to former Vice President Joe Biden are debating the idea of packaging his presidential campaign announcement with a pledge to choose Stacey Abrams as his vice president."
