I would think that if they can tear down his empire and get jail time for his kids it would drive him further into the unfiltered frenzy, fully unraveled.
It's quite obvious that no one in the GOP is going to rein this moron in, and they have all bit off on democracy is dead already, and are setting themselves up in this new authoritarian system they are all in on now.
And that is where we will continue to slip towards unless we at least try to hold these people accountable. Otherwise, we might as well roll over now. Trump controls his family easy enough, but there are those who control Trump and he listens to, like Hannity, Flynn, Manafort, Stone, etc.
Trump is a psychopath narcissist who only worries about his image, and that image is based on his intelligence, which is supported by his financial empire. Your pull the underpinnings out from under that empire, you tear him down into a whiny bully with little hands.
Doing that gives those who oppose him hope for the future. Otherwise, why continue?
Unfortunately we have had the disappointment of the Mueller probe to set the table for us, expectation wise. I still think there will be more come out on that concerning how it was throttled by the Trump administration. Regardless, it left a bad taste in our collective mouths. Still we must remember that Mueller would have gone a lot different if McConnell and his band of goons wasn't leading the impeachment and denying all the credible witnesses, same as in the SC hearings.
