Even the blue states are mostly red outside the metro areas.
Just here on the left coast, the California inland valley, Eastern Oregon and Eastern Washington are VERY red (just ask Jim Robinson).
How ‘bout we get all the red counties to secede. And then we impose a “naval” blockade on the “islands” of the Urban Archipelago. See how long they last before capitulating. After all, it’s not like the British or the Prussians can come to their aid these days!
