Trump will prevail IFF he can find a way to deal with widespread cheating and stuffing of ballot boxes which is being executed, and will be further energetically pursued, by the democrats.
Without cheating, the democrats are sure to lose the popular vote, and probably the electoral vote, as well.
But the democrats have no intention of losing the election.
That is why you court the black vote in the cities. Makes it harder for them to cheat. Trump needs to visit the inner cities often.
