Vance wants to usher in the technocracy. And not, like, the sci-fi dystopia one where actual engineers and scientists run things but get a bit eugenics-y.
My unfounded conspiracy theory is that the republican handlers will have trump killed either before his term starts or short afterwards so they can have a much more controlable and competent Vance in charge to better push their agenda. And they will make it look like a Demkcrat did it as well so they fan the civil war flame even more innthe process.
