It's odd to me that the reasoning given here and in the article for this problem for the Democrats is that they aren't acting Republican enough and they are too leftist.

For the most part the average Black voter doesn't identify as Liberal. And that makes sense when you think about it. The median Black voter is a rural or suburban 50+ year old who left the Republican Party because they endorsed the Southern Strategy, not because of conservative policy support. So being "more leftist" isn't really going to win more of the black vote. They're already winning the black vote that cares about "leftist" policies.

Also I'm sorry I can't leave it, but are you saying that the BLM "cohort" prefer trump in there? I'm not going to say that anyone is enthusiastic about Biden, but Trump encouraged beat downs across the country and threatened to march the military on these folks.

Added a highlight for the important part. The BLM cohort is not likely to vote for Trump this election. But they're also not likely to be energized to vote for Biden. And history shows us that unenthusiastic support leads to low turnout. And part of why they're so unenthusiastic is that the Dems ran the "Anti-BLM" ticket with Biden/Harris.
