US Supreme Court Judges don't have fixed terms like in India.
Also the number of Justices in SCOTUS is not fixed by their constitution. So any party can pack/stack Jugdes in SCOTUS.
Trump is reaping benifit of it.
Definitely not as a VP.
He might be offered a place in his cabinet only.
In most likelihood he might be Secretary of Press if Trump "returns" to White House.
Nothing's gonna happen.
Democrats now have a hard grip on every institutions, be it law enforcement, media or judiciary.
FBI is still sitting on Hunter Biden's sex tapes with minors for more than 2 years.
