I think choice and/or the illusion of choice needs to be there for either side’s fringe elements to have a safe outlet for their frustrations. There needs to be a viable left-leaning party to control potential socialist or communist agitators. If they just completely shut down the Democratic party, then there’s the potential that somebody outside of the control of the aristocratic classes comes to power. Having the Democratic party around gives them a chance to funnel those people through the system and subtly bend them and make them more agreeable to the system. So maybe somebody would’ve been a bomb-throwing anarchist advocating for blowing up the status quo and beheading all the billionaires, but when processed through the Democratic party, maybe they turn into somebody like AOC or Bernie Sanders or something, still willing to work within the system and less likely to advocate revolution.
I’m still not sure about Trump, he still seems like an abnormality or a glitch in the system. I don’t know if he went AWOL and the aristocracy doesn’t want to move against their own, or if he’s just part of “the plan” to move the country to the Right and having a crazy man-child as president gives them cover to push through all their extreme right-wing policies while everyone else fixates on the latest dumb thing that Trump tweeted. Or maybe it’s all just anarchy and there is no conspiracy of the aristocracy, I don’t know. Trump’s existence just seems like one of those things the TVA would’ve come in and destroyed this whole timeline over.
