Jeff, there simply is NO black female who does not terrify whites and would lose the entire suburban vote.
Kampuchea (Harris) did terribly with black voters in the primaries. They did not consider her black. Abrams would lose 25% of the white suburban vote. Moreover, Trump has held firm in six polls over FOUR YEARS at between 15 and 25% black approval. If he gets 12% (which he will) and then another 3-5% blacks stay home (they will), it will be a blowout in some areas.
Consider the last poll had Demented Perv Biteme at only 74% black support.
