That will NEVER HAPPEN. The Dems would lose the black vote. They've been feeding the racist monster, and it must be appeased.
Without 90% of the black vote, the Dem party would cease to be a national party. They simply could not win a national election ever again.
They would rather see the United States ripped to shreds than suffer than fate.
There is NOTHING that would make the Dems lose the black vote, IMO. They have been thoroughly and properly dumbed down and brainwashed.
