Nah. Trump is a cult. When he loses--and I do mean when, but lets be real it unfortunately won't be a landslide-Trump himself will not go away. He will rally his cult base around the election being stolen and the deep state indicting him out of corruption. There are plenty of losers who were elected as real post-Trump white supremacists like Ron DeSantis, and even the Vivek Ramaswamy grifters of the world, who will take up the white supremacist "MAGA" conservative cause.
In fact its not so much the voters, or the politicans, but the right wing media apparatus that will determine the future of the party. Trump became the leader of the conservative because he was annointed by the conservative media, not the party itself who wanted him to go away. People who identify as conservatives are dumb reactionary sheep who belive "the liberal mainstream media is lieing", repeat whatever they're told by their extreme media figures, and then projects their behavior onto liberals. Media figures like Charlie Kirk, Matt Walsh, Candace Owen, Crowder, Knowles, and entire networks like Fox News, Newsmax, Dailywire. These people and companies have made it big embracing white supremacy, their audience have stayed glued to this shyt like its a drug, and by the end of the day they care more about money above all else. And if supporting Trump at any cost, defending racism, and sensationalized shyt about blacks, guys, and immigrants is what the viewers want and is making them endless bread, that will continue being the conservative movement.
They collectively believe in and do what their media tells them, and their media does what keeps viewers watching and makes them money. Even if they have to lie. And our political discourse and stability as a society suffers for what these greedy bigots do. There's no room for and no turning back to wholesome moderate conservative figures who want to work with liberals and agree with the left on some things. That don't make money no more and it ain't going back.
