No one knows for sure. The Democrats would mostly likely have gotten indictments and had a circus trial. Jurors have to be unanimous, so a conviction is not certain in a trial. If he was convicted, it is not certain what the punishment would be. That would depend on what he was convicted of and what the judge felt was a fair punishment. Then there would be appeals, delays and possible higher appeals.
