It confirms that younger blacks are less democratic. I can see someone like Kasich or Rubio peeling off younger black voters even better.
Not quite as much of a gap as I expected to see. With leaners, black voters 18-29 give Trump 9% of their vote, compared with 8% of over 65s. 4% of black 18-29s are voting third party however compared to literally 0% of black seniors.
This is a very good poll for Biden and if true alleviates some of my fears about Michigan and Wisconsin, two states where I expected a decreased share in the black vote to hurt Dems the most.
