Here in Mesa County, CO, the superintendent of the Colorado National Monument wanted to block propane deliveries to a village (Glade Park) south of the Monument. After threats that the sheriff would escort trucks past the rangers, the director backed down. She is no longer present, apparently removed from her position.
County Commissioners and Sheriffs, at least in Colorado, have way more power than people realize. A scenario where sheriffs start arresting federal officers for breaking state law would be much more interesting than ranchers vs. feds.
Power not used in not power at all.
