Barr is excellent but he can only do what he can do within a totally disloyal environment. One of the reasons things calmed down for a couple of weeks is that federal agents were arresting ringleaders and hauling them away (I dont know where they took them) to await trial on federal charges.
If he went out and bragged on this, how long do you think it would last? The Dems are already trying to get Barr out of office and up on criminal charges. So that should tell you all you need to know.
