Take a look at a US county map that shows the results of the recent presidential election to see where the divide really is. Better yet, look at a national voting precinct map. They both show that it is an urban vs. rural/smaller city divide that politically separates the nation. Yes...there are a few rural places that vote Blue, but those can be explained by FedGov entitlement dependencies, or urban workers with long commutes in tiny northeast states.
The battle for controlling political philosophy is not so much Red State vs. Blue State.......it is Red country and towns vs. Blue urban "city-states".
In fact...when reduced to its lowest denominator the battle is between the whole dadgum Red country vs. the thin Blue I-95 corridor from DC-Boston + Chicago + LA.
Someone living in rural western Mass. probably has much more in common (with respect to conservative political philosophy) with folks in north Texas than he does with nearly everyone in Boston.
