The psychological weakness that will be the undoing of DRUMPF: Unpopularity polls
He has already been reversing the supposed "policy positions" that fired up his base, a base consisting (let us remember) of *ONE FOURTH* of the eligible voters (since only half of those voted), not to mention the rest of the population. The further he goes with that reversing thing, the more his base will turn against him, and with the same ferocity that drew them to him in the first place.
The rest of us already detest him. So when the popularity polls start sinking to the all time lows, his balloon ego will be *PRICKED*!1 Pop. The other thing will be the unceasing ridicule and mocking, which the Biggest Thing about him canNOT tolerate. His *EGO* -- what did you think I was referring to, certainly not his "billions" or that other thing that will be living separately from The Melania most of the time.
By the bye, BERLUSCONI had 6 or 7 billions, much more than what DRUMPF claims to have.
