The assumption to make here is that Trump is willing to try to do everything he's said. This is a guy who literally tried to ban Muslims after all.
Personally, I think that the tumult of his administration is going to get in the way of its own agenda, as evidenced by his first presidency. Half of the people on his staff will be gone before the first year is out, and Trump is going to spend more time golfing than he will actually governing. His biggest focus will be on monetizing the presidency, and he surrounds himself with incompetent sycophants.
These and other factors make it difficult to say what he will actually achieve.
As for the ACA, it was a conservative court that stopped him the first time, so the SCOTUS is no slam dunk. I don't think anyone can definitively state what will happen with regards to health care in this country.
You can speculate on that, but history would demonstrate that you're probably wrong. Hell, Trump tried to get his own VP assassinated last time.
I'm sure they think they can control Trump, but as we saw from 2016 to 2020, they can't. That's especially true at Trump's age and with his cognitive decline.
Normally I would agree with you but I think Donald has lost touch with reality and we are letting a dementia patient run the country. I don't think we could be in more dangerous territory. I mean, he isn't even playing golf anymore.
