A Republican? Step down from whatever position he’s in? My friend, you have a far better chance of enjoying a three-way with Beyoncé and Giselle Bundchen than seeing DeSantis resign. In his eyes, he’s done nothing wrong, every move he made was spot on right and it was everyone else who screwed up.
Trump was never interested in uniting the nation from jump. He’s used fear and hate of anyone and everyone who wasn’t white to rally small minded bigots around him and build his base that’s unfailingly loyal to him, not the GOP, which is why Republicans look the other way and say nothing when Trump does all sorts of crazy shit, they fear Trump’s followers, not Trump himself.
