Now, they have reached the degree of alienation and commitment to destruction that they will escalate "resistance" to genuine obstruction and violence. Notice the new tactic of "occupying" ICE facilities; the small scale terrorist attacks and aggravated menacing against government officials; the overt calls for violence. I suspect these will escalate until some hit and run raid against the government elicits a violent response.
If the upcoming elections do not assuage the leftwingers, and if Congress remains in republican hands, then I would expect trouble beyond what we have seen so far.
“In those states it will be guerilla attacks.

College professors, college students, to start. Even the most red states have 20-25% of the population vote very liberal. Outsiders could also travel to the state.
