Biden leads in those polls by an 83% to 8%, or 75-point, margin. That, of course, is a huge advantage for Biden, but it also represents a small improvement for Trump since 2016.

Hillary Clinton was ahead of Trump by a 79-point margin among Black registered voters in the pre-election polls taken right before the 2016 election, as compiled by the New York Times’ Nate Cohn. Biden, for what it’s worth, is equaling Clinton’s 83% in those polls. Trump’s picking up a lot of the vote that went to third-party candidates…

Biden currently has such a large lead overall that Trump’s small gain among Black voters doesn’t really matter in the grand scheme of the 2020 election. But if the race for president tightens, Trump’s small gain with Black voters could make a difference. It could cost Biden 0.5 points nationally on the whole compared to where Clinton ended up. That may not seem like a lot, though it could make the difference in a close election. And, of course, Biden’s margin with Black voters may tighten further if the margin with other voters also shifts.
