That's a very pessimistic slice of the Black upper-middle class. As a focus group I'm not sure what it really tells us. In the end - correct me if I missed something - but every person the author interviewed there affirmed their vote for Biden in November.
Pessimistic...yes. Every interviewee voting for Biden...yes. But my main take was for all those blacks who won't vote at all because as a 78 year-old, rich white man, Biden is just 'more of the same'.
