The scary part is JD Vance will be President in 2 years.
Trump will stay in office for two years long enough to Pardon himself and all of his cronies. Once that's taken care of and he runs the country into the ground he will step down.
Possibly less.
Trump still has to be sentenced and be tried which they may try to speed up to happen before January.
I honestly don't think Republicans will mind throwing him to the wolves and letting Vance step in immediately.
