As much as I can't stand Trump personally, I tend to be of the view that his second term will be much the same as his first.

It won't be fun by any measure but I don't really buy into the prophecies of doom that are common currency right now.

Trump showed again and again that he fundamentally did not understand the machinery of state. A lot of his presidency was him trying to do something and getting told "no" and then throwing a fit. He went into office thinking "I can do whatever I want because I'm the president" and his first term was a lot of him finding out he couldn't actually do that.

He's also just not someone with a fundamentally ideological mindset. He has no personal politics that extend beyond what directly benefits him, makes him feel good, and makes him look good. Part of Bannon's frustration the first time around was Trump couldn't stick to the script. He couldn't be reliably guided to do the kind of focused right-wing stuff that people like Bannon wanted. "Growth and change" are not exactly bywords in the Trump household so I very much doubt anything has changed in that department.

He's just not dictator material.

As to if he'll leave, I'd bet money on it. He won't go quietly but, at the end of the day, to stay in office he would need a lot more support from the military and other wide aspects of the civil infrastructure that, even if they like him, are not willing to follow him to that extreme. Trump inspires this kind of devotional loyalty only from a small subset of his base and a lot of those fanatics are...I don't want to be rude but let's go with "possessed of an understanding of the world not rooted in a shared reality." They're not people in key places in government.

I do also think it's also an open question as to if he'll even survive his full term. He takes famously poor care of his body, proactively avoids meaningful exercise, eats like a college student, and, lest we forget, is 77 years old. If he gets elected in 2024, he'll be 81 in 2028 which is the same age Biden is right now. The presidency is also a stressful job, even if you approach it the way Trump does.

Even having some of the best medical care on the planet, I am skeptical that he's going to make it another four years.
