Remember that Trump’s 2020 vote share increase among black voters was more because of decreased turnout among this group than people flipping from D to R (in fact, 2020 exit polls indicated that only 1% of black 2016 Clinton voters flipped to Trump in 2020). The decrease in turnout can be attributed to Democrats not reaching out to this group as much as they did before, along with the fact that most blacks have traditionally preferred Election Day voting over absentee voting (the latter of which dominated the 2020 election).
Yeah, dems didn't reach out to black voters at all in 2020 where BLM dominated the news. They definitely did not bend over backwards to win their vote
