If Walz magically develops a spine then the Minnesota guard clashes with ICE leaving many dead.
Best case scenario other lib states join forces, deny the federal government all resources, and the second civil war begins. It ends the same as the first, with no real punishment coming to chuds except those who died in battle, next civil war begins 150 years later between the Ultraliberals and the Neo Neo Nazi movement, but goes unnoticed because the rest of humanity is in space.
Worst case scenario, nothing happens.
