No matter what his handlers tell him what he needs to do, he is undisciplined and incapable of comprehending. He knows he's going to get humiliated in the election so all he can do is cry that it's unfair and rigged. If his supporters riot after his defeat, at his urging, history will be even less kind than his abysmal record as potus will warrant.
I look for the GOP to lamely attempt to reinvent the party and try to claim that donald, a guy they enabled, isn't at all what they stand for. They will throw the "uneducated base" under the bus, blaming them for donald's rise, when in fact, their party started down this path with their so called "southern strategy".
