Add in conservative states in the general area such as Idaho, Arizona and the remaining Great Plains States in the west and Indiana, Kentucky and the former Confederate States in the south and you are left with a rump collection of urban states which are still greater than a collapsed national socialist government can deal with.
In fact, such a government would have a hard time dealing with giant cities such as Los Angeles, San Francisco and Boston to Washington in its midst, let alone rescuing fringe enclaves such as Boulder, Denver and possibly even Pittsburgh on its frontiers.
Rural America is largely still somewhat sane.
The degree of self sufficiency is pretty small. Could that be overcome? It depends.
Pretty scary times.
I’m not yet paranoid about it.
