I think there may be 2 sides to this.
The Priebus side, which is essentially a weaponized version of garden-variety conservatism. I think all of the traditional toolchain works on this including calling congresspeople, donating to the ACLU, marches and protests, etc.
The Bannon side doesn’t give people much to do. The folks who need to fight that are in the Deep Gov. The problem with the Bannon side of it is that they have been so successful with the Cambridge Analytica approach to divide and conquer, and with control over the intelligence apparatus in the hands of that clan, we can try things like leaving the United States but that would probably be the limit of it.
