The North would be a liberal-aligned nation, and the South would be a conservative-aligned nation. Would our congresses not get more done without the 50% opposition? Would we not have happier people being able to have their president elected. We would be a more stable with our foreign policies (more predictable). We could both run the economies the way we wanted (the North Protectionist probably, the South Free Trade)...
Should we give up our status as a world power to have happier populations?
