When lower levels get busted they give names of a higher up. Basically my guess is that there is a chain. Lower level won’t get there direction from the governor. It goes one level at a time up the chain. If one of them dies it could break the chain. Keep your eyes open to see if people involved in the election suddenly “committing suicide”. Ruby needs to speak up. If I was her I would cut a deal and want to stay in the public eye as much as possible.
You are assuming no corruption in the FBI or DOJ. A plea deal might end up with her hanging herself in prison.
