Honestly Miller strikes me different. It’s not coincidence he’s survived so long.

He’s not an idiot. He knows how much damage he can absorb and how to position himself to not take more than that. He never positions himself as the implementation person who will take the hits. He’s the idea guy, and the manipulator/cheerleader. He doesn’t seem to expect trump to take care of him for his loyalty, so he doesn’t position himself to require it.

I think ultimately he won’t be thrown under the bus because his relationship with Trump is mutually beneficial, and they both see it as transactional. For both of them, the other is a means to an end. Soul mates in hell I guess.
