The practical issue with using the Insurrection Act and Executive Orders to seize control of major liberal cities and arrest subversive governors, mayors, etc., is the loyalty of the armed forces. Trump has cleared out a few Deep Staters from the Pentagon and many in the elite units are very patriotic. However, there are still too many Obama appointees in flag ranks. Then there is the issue of blue state National Guard units. Additionally, I think the Trump coup is a joint Democrat-RINO operation. Even if the two Republican candidates win in Georgia, there are enough RINOs in the Senate that would join the Democrats to impeach the President with two thirds margin.
I don't want to be a Debbie Downer, but barring divine intervention, the situation is bleak.
