I agree. Vance might be more dangerous IF he had Trump's massive cult of personality, but he does not and never will. He is not charismatic, popular, or likable. The MAGAs won't storm the Capital for him. If it were Vance doing all the same destructive things Trump is doing now, even if he kept saying "this is what Trump wanted," MAGA would turn on him far more quickly once it started affecting their lives and livelihoods.

Trump is a singular figure with his cult and can't be easily replaced. More likely they won't be able to replace him at all and MAGA will break down into squabbling factions once he is gone.
