Next presidential election isn't until 2024.
Are you worried about him being installed in 2021, in some last minute overturn of Biden?
IIUC, there is now no chance at all of him being installed president in this cycle by any democratic or legal process. My understanding is that he would need an armed coup, and to end the USA as a democratic country. And although I'm sure he dreams of such things, I don't see that happening.
The real damage now is in the medium and longterm aftermath. He's done such profound damage to the democratic institutions, and been such an effective rabble-rouser, that the madness won't easily go back in the box.
The people funding and steering him won't go away either. Once they've used up this frontman, they'll pick another, or attack via other routes.
