@farmerman,
Interesting times, indeed.
His could explode (arguably, he is already) but god knows what that might look like if some critical ego-damage or threat of it looms. I can't imagine that he is unaware of the damage he's done to his brand (and future income) but perhaps I'm over estimating his ability to perceive it.
What does he do as it becomes clear he's going to lose big if he's capable of that? What he says one day to the next has no consistency so he could loudly quit before the election. "Rigged! Unfair! Media and GOP backed crooked Hillary and I'm above that!" It's possible.
If he carries through and gets his ass handed to him by a girl, then everything he's using to run the con now will increase in volume and insanity. And then what does his base do?
We ain't seen anything like this before.
