My guess: Trump will not go to jail becasue he will cop a plea to obstruction of justice. He will avoid the charge of sedition, which could get him 20 years in jail. But he will have to remove himself from the politcal stage as part of the plea deal. Hopefully he will get four years of probation with no media contact as one of the provisions.
By hope, which may be unrealistic, is that his indictment will come before the mid-terms. Merrick Garland is NOT Robert Muller. He will do his job.
