That does seem to be inconsistent with each other.
Remember, blacks constitute only 13% of the population, so a huge swing in the black vote isn’t all that many percentage points in the total vote. Yes, it matters, but no, the numbers aren’t all that out of whack.
Lots of COVID Karens in MI, apparently.
Unless they oversampled black voters?
This thread (post 13) shows Trump ahead by six points in Michigan.
That would be more consistent with the high performance with black voters:
