The choice of Howard offered Mr. Biden an opportunity to shore up support in the most loyal constituency in the Democratic Party, one that he needs to win re-election next year. While polls show continued strong support for Mr. Biden among Black voters, political analysts and party strategists have expressed concern about an enthusiasm gap that could complicate prospects for the president, who needs high turnout from his base.
Mr. Biden has been stymied on goals like cracking down on police brutality and bolstering voting rights. He did sign an executive order on federal law enforcement last year, although crucial pieces of the order have not been implemented. Many supporters say he has fallen short on his pledge to make systemic changes to the criminal justice system.
But he chose Kamala Harris (a Howard graduate) as the first Black vice president; appointed the first Black woman to the Supreme Court, Justice Ketanji Brown Jackson; and has put more Black women on the federal bench than every other president combined. Unemployment among Black Americans fell to a record low of 4.7 percent in April, and the gap between white and Black jobless rates shrank to its smallest ever measured.
Of particular interest to his audience on Saturday, Mr. Biden has developed a program to forgive $400 billion in student loans over the next few decades, wiping out up to $20,000 apiece for those who qualify. But the Supreme Court appears poised to invalidate it.
Mr. Biden won 92 percent of Black voters in 2020, but only 58 percent said they approved of his performance in the latest Associated Press-NORC Center for Public Affairs Research poll. A May survey by the Economist and YouGov put his approval among Black adults at 71 percent, but only 46 percent wanted him to run again.
Mr. Biden found a friendly but not exactly exuberant crowd on Saturday. Graduating seniors and their families filled much of Capital One Arena, the home of the Washington Capitals and Wizards, and greeted him warmly, although a dozen stood in protest, some holding signs about issues like military research. The ambivalence among students and graduates was evident in interviews on campus before the ceremony.
“He’s a pretty good person,” Mariah Davis, 19, a mechanical engineering major, said of Mr. Biden. “He’s just really trying to advocate for a lot of groups of people who are unheard.”
