Vice President possibly. Pretty sure that doesnt have the birth location restriction. Which would potentially risk a partial term if the elected President died/became incapacitated.

Not sure if he's going to be willing to write the sort of checks Trump would want in order to have him on the VP ticket.

Only other option might be Texas governor. I doubt his ADHD would let him focus on that long enough to achieve it, there are a huge number of people he'd need to bribe, bully or discredit to get that. It's hotly contested so there's going to be a lot of people blocking and undermining the attempt.

In short I don't think he could keep his attention on it long enough to grind it out, and his autism is going to nobble his ability to do the soft influencing via speeches and glad handing that a "proper" political role requires.

VP is a real political role but you don't necessarily need excellent political skills if your presidential candidate is good. Given that would be Trump it's hard to say how it would unfold.

I personally hope the Trump 2024 campaign is a car crash regardless of veep candidate.
