There's a scenario there where Trump becomes President and then a state declares him guilty. What happens when they try to make him serve his sentence?
This is not a question we should ever need to answer, but we're staring at the possibility.
No way Rico case happens before election, the DA couldn't keep her pants on. It will be years before Rico trail starts and by then all Trump needs is governor or DA lacky to drop everything. The Jan 6 case is the only one that could happen before election.
