I don’t know about that. A lot of black people still don’t like Trump because of “Republicans are racist”. They call Candace Owens a “uncle Tom”. Trump will get 5%-10% of the black vote. Nothing less, nothing more.
Are you high?
Trump got 8% of the black vote in 2016, so your 5% number is utterly ridiculous.

At a minimum, in 2020, Trump gets 10 to 12% of the black vote.
I’m curious how many Black voters do you know? With how many do you talk politics? You’d better do more research.
