The problem faced by either the left OR RINO republican, would-be dictators is that the majority of troops would join with the American people! That coupled with the fact that there are one hell of a lot more of us than of them makes the whole thing quite silly.
You honestly believe that the US Navy would not side with the govt? Would you lead the charge into Camp Pendleton or try to take over a nuke sub or aircraft carrier to test your theory?
