Barr is entrenched in “Spook Politics” developed by Bush41 as the standard and carried forward by all POTUS since 41.

As long as the DoState and the CIA get their operating money.
It wasn’t until post-HRC that the CIA was levered out from under DoState.
DoState, its military attachés and SES-CIA in Europe is what Rush meant when referencing a shadow government.
It is important to note that these same SES agents are fully part of any Devolution-Continuity of Government plans; many think that those boosting such concepts are themselves conscripted agents.
These agents stay in power (shadow government) as long as WE the People desire to have a continuity of the current government; that is show fear that government is crumbling and “someone has to do something”!
Future proves the past.
