Legally the only way he could run again would be to modify the Constitution which is simply impossible since the Democrats will never agree to it.
Which means he'll have to do it the Trump way by forcing things. => 2028 comes up, he announces he's going to run again and his fanbase will support him.
=>The Republican leadership will then have to choose between supporting him again or not supporting him and splinter the party. They will probably choose to support him which will trigger probably the biggest constitutional crisis since the Civil War.
=>Democrat states and maybe a few Republican will refuse to put him on their ballots and the Supreme Courts has to get involved. A Supreme Court that is dominated by 6 Republican appointed judges at the moment (3 of whom were appointed by Trump). If more Democrat appointed judges die during his current term, then there's a fair chance he'll have complete control over it by the 2028 election. They might actually reinterpret the Constitution to let him run.
I'm honestly very concerned for the US. Maybe he chokes on a chicken wing and we can avoid this whole mess.
He said he won't ask Trump for a pardon since he doesn't think he'll be granted one.
But this is Santos we're talking about. He'll definetly try.
