Musk got himself into this hole, so if a democrat president comes in 2029, there's a high chance now, he'd be deported. Can happen sooner as well, depending on midterms.
Yeah thats a good point. You never know, the pendulum might swing far to the left and his billions might not save him. I do concede thats its really unlikely.
In order for him to be prosecuted, several highly unlikely things have to occur.
Trump doesn't pardon him. I can't really see this happening. If they have a falling out, then Elon will just pay him off. It's not like Trump will turn down a bribe.
A democrat is elected president in 2028. After that, demographics substantially reduce their chances of being elected (https://www.pbs.org/newshour/politics/democrats-future-crisi...). They would have to either abandon progressive views and move right or offer an incredibly compelling candidate. Both of these seem unlikely to me. After that, people in red states will determine the future of this country.
