Mr. Biden, and before him Hillary Clinton and Barack Obama, won the nomination largely because of their strength with Black voters in Democratic primaries.
Mr. Pritzker, the governor of Illinois, is helping to plan and fund next year’s Democratic National Convention.
Mr. Newsom, the governor of California, has offered himself up to debate second-tier Republican candidates on Mr. Biden’s behalf.
And yet Mr. Biden will turn 81 this month.
If anything is durable about his polling numbers, it is how weak his standing is among the party’s core constituencies.
