So, I follow what you're saying, but I don't buy it. Everyone wants to bucket the Trump era into epic, far-reaching theories.
Rush Limbaugh was the most listened to host on radio, and by far the most influential conservative radio host, by 1990. From the point Rush became dominant Republicans have nominated:
GHW Bush
Bob Dole
GW Bush
John McCain
Mitt Romney
Now, I haven't listened to 30 seconds of Rush in the last 15 years. But I used to listen plenty, and the Rush Limbaugh that captured the imaginations of conservatives had almost nothing in common with the scattershot lunacy of Trump, unless you consider Mitt Romney no different from Trump, in which case...good day sir.
Here is the thing, it takes time for some things to take full affect and show themselves. At first Limbaugh was likely a side distraction that was influential but didn't cover how people thought. Later on he became more and more the voice of the Republican party.
And I would also point out that Limbaugh might have changed since then. Guy always called Michelle Obama "Moochelle". That isn't making intellectual arguments in the least.
The fact that you characterize Alex (presumably?) Jones as a voice that conservatives rally around again kind of gives away your game. 90% of Republican voters would only know of Alex Jones vis a vis the way he's been elevated by the mainstream media, if at all. Republicans haven't exactly been "9/11 was an inside job" fanatics.
You can cherry pick lunatics anywhere and try to assign them to the other "team", but that doesn't make it a relevant way to look at the world.
Then I suppose a presidential candidate going on the show of Alex Jones and saying he has a great reputation . . . that sort of thing should kill his candidacy shouldn't it??

I just disagree with your (and really everybody's) attempts to synthesize Trump into a standard framework, or make sweeping hysterical conclusions about what it means for the future.
I think you have to. Trump has been such a radical departure from the norm and his hold on the party so complete that I don't think you can just presume that he's an isolated incident anymore.
Republicans used to believe in free trade and did not trust Russia. They wanted presidents who where tough on Russia and tough on North Korea.
In about 4 years Donald Trump has converted the Republican party into supporting tariffs and pushing for closer relations with Russia and North Korea. Republicans switched their entire ideology to fit with Trump. They also consider any criticism of Trump to be a betrayal, no matter what Trump does. The Republicans could have easily joined with Democrats and undone the tariff's that their pre-trump ideology hated so much. But they would not dare disobey him like that.
Republican House and Senate candidates used to say they would be a conservative voice in Washington. In the 2018 mid-terms they said they would be a voice for Donald Trump. The senate race in Indiana was certifiably insane. There where 3 main candidates in the Republican primary and every single ad was about loyalty and obedience to Trump. Then we got to the general election and the incumbent Democrat ran ads quoting Reagan about peace through strength and saying he wasn't going to allow "socialists to take over our healthcare". The Republican again ran ads talking about all the times that the Democratic candidate disobeyed Donald Trump.
Republicans no longer support an ideology anymore, they support a cult of personality around Donald Trump. That doesn't just change, especially if he wins again in 2024. It will only run deeper and deeper. If we still have an election in 2028 it will likely include someone just like Trump if not one of his children.
