While Project 2025 suggested the use of the military as law enforcement in Democratic cities - in reality this can only work in Red States. The federation style of government gives power to the state in the form of the National Guard.

I believe there is some sort of power that enables Governors to draw up reserves too, and any federal military stationed in the State.

Sort of like the Fediverse - the instance admin ultimately decides what can and cannot be fed into their instance, and enforce their own moderation rules within it.
