Your analysis is interesting and credible. In hindsight it is amazing Trump, or any non-insider, managed to pull it off in 2016. All things considered - all the mistakes he made - I'm still very glad he did.
It will be interesting to see which way he goes now, being the most influential figure in the party. Play ball with the insiders, take a shot at actually reforming the party or just fade away. Does it even matter.
It's surprising, but in a way, it's not.
After Reagan, who Americans loved, the Americans found the national primaries were always giving them RINO squishes.
Bush and his Read Me Lying Lips pledge,
Bush handing us that draft dodging rapist,
Dole the Mediocre Viagra Salesman,
Bush the Compassionate Not-A Conservative
Romney, the ONLY candidate that couldn't campaign against Messiah-Care.
And then we were threatened with Jeb! or Kaysick.
The people revolted against the revolting line-up and just LOVED Trump, because Trump was the first, and only, candidate in 28 years who FOUGHT BACK. And that's why the Americans still love their president and gave him his second term in 2020.
If he runs in 2024, he'll get a third term, too.
He's not going to coddle the RINO insiders who have spent their careers betraying everyone who voted for them.
