I agree with your assessment. This judge will not outright dismiss the case but will punt it so he can save himself.
The Judge will probably try to protect the institution of the Fulton County justice system while putting a stop to the Fani Willis Witch Hunt by removing the tainted prosecutors and Fulton County from the case.
He has more than enough to dismiss the entire case but not sure he is willing to go that far. Suspect that he will let another Georgia entity make that call. One thing for sure, Fani and Wade have fun and eventful election year in store for them. Probably going to be too preoccupied for that trip to the Seychelles Islands this year.
