The ish I hear/read from my Black working-class family in NYC is straight in line with the stuff you see in TLR, the Black working-class man is not enthusiastic about his place in the democratic party. The apathy is prevalent and their dislike of Trump is not intense enough to move the needle, and sadly I don't think the George Flloyd situation moves the needle for them. But I don't think Black men are going to Trump in substantial numbers, but voter turn out may remain mediocre. And that doesn't bode well for the Biden campaign, but with the window being so small I don't foresee them creating a policy that creates excitement amongst Black men.
I have stated both here and TLR that the condescension towards Black poor and working-class men can potentially have substantial negative consequences. The not so subtle classism, dismissiveness, and lack of power or visibility within the media have led to similar attitudes towards technocrats that you find among white working-class men. The obvious difference is that Black men lack the same amount of leverage and their downside risk is much greater. Black working-class men aren't trying to hear some complex Chomsky lite analysis and they are already disillusioned with mainstream liberalism, and so the persuasive methods have to change.
