Mike -- In a way, you are describing 4Ts as communitarian and 2Ts as libertarian. That the social and economic spheres are split philosophically in both major parties is interesting, but may be an anomaly. It's well established that families are more stable in the Blue Zone, even though it's the Red Zone that makes it a virtue. So behavior and philosophy may be at odds on the social level, but not on the economic level. There, the Red Zone praises the virtues of hard work and self reliance, even though the achieved results are worse. The Blue Zone tends to be the more supportive and wealthier. In both cases, the underlying bent is communitarian in Blue Zones and libertarian in Red Zones. That seems to follow recent history, where the redder Sun Belt has been dominant, with the bluer Snow Belt starting to rise now.
I'm not sure if any of this fits your thesis or not.
