I don’t know if we should be so sure that he will be gone in three years. There is no incentive for him to relinquish control peacefully. We’ll have to give him a plea bargain, or a pardon of sorts, to incentivise him stepping down. Without one his back will be against a wall (or iron bars in this case), and he will gladly escalate to stay in power to avoid incarceration.
I'm far more concerned with the younger, smarter and just as evil minnions who are currently learning from the master how naked & deep the corruption can go without consequence. President Vance and VP Rubio may be less shocking but could be even worse for everyone.
Since when does he need to worry about incarceration? He's already been found guilty on 34 felony counts and nothing happened.
