Urban versus Rural not North versus South-

I've noticed over decades of living in about 40 places around the USA that the real social and political differences are between Urban and Rural, much more-so than North South East West. Atlanta and Seattle are Liberal, but the rural northwest has pockets of hardcore white supremacists worse than rural GA. Texas is far-right as a state, but Austin is as Liberal as NYC. South Carolina is big-time conservative, but Greenville is way more Liberal than San Diego CA...If you look at the electoral map you see that Urban is Blue and Rural is Red all across the USA.
