I feel like I'm losing my mind, but that article cites Emerson polls and discusses them at length with somebody who conducts those polls. When the citations link to Emerson's cite, they go to the following two articles:

https://emersonpolling.reportablenews.com/pr/november-national-poll-support-for-impeachment-declines-biden-and-sanders-lead-democratic-primary

I'm ready to make all kind of concessions that I read too fast or skipped over something important, but I haven't yet found anything in those articles about Trump's support among black voters. Like, I'm not saying that somebody is spinning poll data. I'm saying those two articles are about different polls entirely.

Not even arguing at this point. Just want somebody to show me the actual poll that keeps getting cited because it's getting weird.
