What does any would-be tyrant need in order to gain control over the lives of citizens? Three things come to mind: martial law, socialized medicine, and food dependency.
In at least two of these categories, President Obama has already succeeded.
By way of executive proclamation, President Obama has secured for himself the power to declare martial law in the event of a national "emergency," real or contrived, and without the accountability typically required by the Posse Comitatus Act and the National Emergencies Act of 1976.
This is the legacy of the "conservative" Bush administration. National emergencies have now been transformed into power-grabbing devices thanks to the virtually unnoticed National Security Presidential Directive (NSPD) 51.
NSPD 51 empowers the president to co-opt all state and local government authority in the event that he declares a national emergency. This is a self-declared power not subjugated to the National Emergencies Act of 1976 as in previous directives.
President Obama quickly went beyond NSPD 51, signing an order creating a "Council of Governors" who would be put in charge of declaring martial law. The directive is in direct violation of Posse Comitatus and the Insurrection Act. This "Council of Governors" answers only to President Obama.
