He’s essentially controlled by them. Using him for his cult of personality. Without him they all fall and fall hard. None of them are anything without Trump and they realised this during his first term when they went from “Trump is the worst thing for America and the party and should be nowhere near politics” to “hit me harder daddy”. Disgusting how they debase themselves for fame and fortune and power.

I saw a video of Rafael Cruz speaking (or rather shouting) and getting very angry about Trump back in I think 2015. You could see he truly hated him. Wish I could find it!
