Agree in principle - Trump is not a great orator. But that's a plus in many circles, because I don't know of many middle Americans who want to hear fluff and meaningless platitudes. Trump is good at touching on the stuff in middle America that matters - family, home, community, work ethic, solving problems. He's able to project those qualities on those who attend rallies (I never have, and have no intention to) which pumps up people who are already pumped up - like those who attend sports events.
Trump is good at mocking his detractors, and God knows, there are more than a few of those. That incenses the GOP elite class and the Left (which includes 95% of the media).
I think Trump is trying to find his niche and that is increasingly more like the GOP father figure. I think that Trump likes being President, but he also likes his new-found role. I do not see DJT as a presidential candidate in 2024, but that does not mean he will not be a factor in the process. He likes the limelight and he likes the power, but he can find much of that in endorsing many, and will likely be part of more than a few rallies - for candidates in many races, including presidential, congressional, gubernatorial.
