Trump is a figurehead and mouth piece only, it’s clear the backing and power behind him is pushing him, not the other way around. If Trump is dead or unelectable then they will sub in someone else. Trump’s “saving grace” is that he was good at speaking in a relatable but obfuscating way which worked to foment the masses against imagined grievances, but that’s not a trait unique to him. He is unfortunately replaceable with not much loss in momentum.
