I agree with most of this, including the very deep rooted issues in the GOP.
However, this country is in desperate need of real leadership. Trump is no leader. As you highlighted, he is a fabulous disruptor, but I don't think he is ultimately what this country needs to actually turn the ship around. There has to be a conservative voice out there that can highlight all the BS that Trump called out, but also find a way to bring the American people together (or at least most of them) and then articulate a vision and future for the country. The tweets, brash personality, etc... can be entertaining, especially the times when he was right. But in the end it is tiring, grading, and at the very least, not professional.
I voted for Trump twice as well, somewhat begrudgingly the second time, although he ultimately was the best candidate that was on the ballot. But, I will be voting in a primary for the first time in my life this next cycle in order to vote against him (if he runs). His personality is not what this country needs or what will actually set this country back on the right path again. I know we can do better than that as a country, and I would hope Republicans can do better than that as a party. Maybe someone like DeSantis, Crenshaw, Noem, or Haley can be the leader this country needs; time will tell.
