To me, the next logical step for folks like Rick Perry, or the Open Carry folks that seem to be a few crayons shy of a full box is making and validating an attempt to overthrow Federal government. We've seen people do this in Nevada, especially when it's clear that the rancher was on the wrong side of the law and that Federal reps were more than lenient, and lately with the derp surrounding the illegal immigrant children that need to be temporarily housed.
What happens if one of those folks from Nevada decides to open fire first? Even if it's well documented, recorded, etc., this kind of stupidity can easily be used as a rallying cry to invoke some sort of second civil war, especially if your opponent has been dehumanized and vilified as much as Obama has?
