Still, what do you think a "they get absolutely everything they want, fire all US government employees and replace them at the low echelon with Billy Bob, the middle echelon with James Holden Bloodfeast III, and their favorite Youtubers at the top echelon" complete and total MAGA victory might look like? 
Try to hold it together and stretch your sense of disbelief that the hogs get the feed they've been squealing for, from mere reappropriated resources (the way nazis murdered and looted and redistributed to their favorite failfamilies) or even something surreal like the incel supporters actually getting government issued slaves while destroying all other safety nets entirely, if you dare.
