I am forecasting a plea deal that keeps him out of jail but as part of it he agrees not to run for nor serve in a public office. Would include long probation, perhaps home monitoring, restricted travel, a humongous fine, etc. plus he publicly allocutes to his crimes.
And then at some point down the road, some time from now, there’s enough state legislature support for a CA that adds some strictures as to who can serve as President beyond having to be 35+ and born in the USA. That would include no convicted felons/pleading guilty to a felony. Who would vote against that once Trump is out of the picture?
