As a non-Republican, it's hilarious watching the Republican party completely implode. Around the time of the election, an argument could be made that what the GOP establishment versus the average Republican wanted were two different visions. Establishment wants the GOP to drop Trump and regress back to a George W. Bush or Mitt Romney-like candidate who is soft spoken, evangelical, very neocon in terms of foreign policy, always talking about the debt and deficit, and continuing to giving tax cuts the rich and deregulate. Republican voters though, who are not part of the elite class, wanted one thing, and that was Trump. His approval rating within the party has always been somewhere around 90%. That's not to say that Trump isn't also a neocon who gave tax cuts to the rich and deregulated. But with Trump, at least there was this veneer of populist, anti-establishment-ness, standing up to "RINOs", the "deep state" and "draining the swamp", being the savior for the little man that has been forgotten for decade, which is the main reason why he is so popular amongst Republicans. The Bushes and Romney were never like this, and that is why the Republican voter base will never vote through a Bush or Romney type candidate through a primary again.
After yesterday's debacle though, and trump (somewhat) finally conceding, I'm willing to bet that a good enough number of the Trump base has left the Trump train (though obviously he will always have his fair share of yes-men because thats how cults work). As others have said, he is no longer the most popular Republican. And right now, there seems to be no popular Republican. The base, as aforementioned, isn't going to revert back to Bush or Romney, and they also seem to have contempt for people like McConnell, Perdue/Loeffler, and many other "establishment Republicans". In the 2024 election, I predict that the RNC will try to completely erase Trump and act like 2016-2020 never happened, and force someone like Nikki Haley, Lindsey Graham, or even Mitt Romney again, down Republicans' throat, and they aren't going to buy it. At this point there's no way Trump will run in 2024. He'll either be locked up, dead, in too poor of health, or simply disinterested by that point. So, the GOPs strategy right now seems to keep doing their same old neocon policies, but embrace the "anti-establishment" rhetoric, though without the unhinged aspect of Trumpism. You can already see this with Ted Cruz, Marco Rubio, Tom Cotton, among others, formerly "establishment-types" who have changed their rhetoric to suite whats popular. Whether the base will buy into this is yet to be known. Or, the winner of the primary could be a non-politician outsider who runs on and continues the legacy of Trump. What's to say that Donald Jr. or Trump's other children, Cucker Tarlson, Charlie Kirk, or some of the other OANN/Breitbart/NewsMax goons that are popular couldn't run? Regardless, it's for certain that the GOP is in a very volatile and frankly, terrible place right now. But I don't think this is the death of the party nor will they be going any time soon. After all, money talks. And its not like the GOP doesn't have a history of breaking the rules and being brazenly corrupt to win an election.
