Well depending on how they count was there a flip or are the ratios different since certain amount of people have moved to the “not likely voter” category. So instead of flip, there is apathy among democratic voters.

Since they say among black voters, not among black population. Those are two different things and it matters which is it. All voting eligible persons, regardless of likelihood to vote, or just likely voters.

Since voter/not voter is not a fixed grouping, there is constant movement over that line.
