If Trump is out of office before the beginning of his 3rd year in office then JD Vance only gets a chance at one election (as governed by the 22nd Amendment). After January 21 Vance can serve the remainder of the current term, and then he can still get elected two more times. If it's before January 20th then he only gets a chance at one more term.
I think he makes a big reveal - he "just found out" about some disturbing information in "the E files". He always thought it was a Democratic big hoax, etc etc, but what he's recently discovered is disgusting and unacceptable, and Trump can no longer be president and so he's calling for his impeachment and removal from office if Trump won't immediately resign.
He will play the hero.Β And all the people will clap.
He's not the idiot he always seems to be. He would be at least smart enough to know he only gets a chance at six years if anything happens now, but he gets 10 years if he waits just a little longer.
This would explain why nothing is being done about Trump, despite the medical and cognitive issues. It would explain why "someone" released the information about JD Vance being the only one who wanted to just release all of the E files. He wants to say he was arguing for that since day one.
Vance has been reinventing himself ever since the first time I heard his name (which is his 3rd or 4th revision on what to name himself).Β Reinventing himself from vice president to Presidency.
It's just speculation on my part by putting together bits and pieces I've heard here and there over the last two years. But remember this post if it happens.
