I watched Tim Miller's interview on the Bulward with Lakshya Jain, a data and polling expert who described Black voter turnout as the major challenge for the Harris campaign in GA. He noted that Black turnout was actually down from 2016-2020 -- yet Biden won. He said it was down again in 2022. So he believes it's a bad trend for the Dems and one that is likely to be a factor in this election, even though he was not making what he'd call a prediction.
I'm not sure what to think. I'd hope Black voters are excited about Harris. And we hear that she has an amazing organization/GOTV operation. And 2020 was an odd situation, given Covid. I'm hopeful that Black turnout supportive of Harris will be in the range needed.
Unless I missed it, they didn't discuss turnout among women. Seems to me that if the relative turnout by women is even slightly higher that expected, then that might be the biggest factor, in general.
