There’s the Georgia election interference case - I don’t know what the potential penalties there are, but they can only delay that one until after the election. And Jan 6. There is the fraud sentencing in NY which, you are correct will likely not result in prison time since he’s a first time offender (lol).
There are two or three pending cases about fake electors where he is an unindicted co-conspirator which could potentially be amended to include him. Apparently now a potential bribery case if that hasn’t already been completely scuttled.
I mean shit the guy has done a fuck ton of crime. He’s already a felon, which means the kid gloves can come off for future sentencing.
I don’t think any of the cases are a slam dunk victory and then prison, but there are an awful lot of options.
