Our divisions are racial and ethnic and class-based and generational, conspicuously so in the Trump era. And they are geographic: The metropolis versus the hinterland, the coasts against the middle of the country. It would not be hard to sketch lines on a map partitioning the U.S.A. into two or three or four more homogeneous and perhaps more functional republics. And if you imagined some catastrophe suddenly dissolving our political order and requiring us to start anew, it is not at all clear that we would be able to forge a reunited republic, a second continental nation.
Moreover, our divisions induce a particular anxiety because each of our two main factions reigns supreme in one particular arena. Conservatism is (somehow) politically dominant, with control of the legislative and executive branches and a remarkable power in the states. Meanwhile liberalism dominates the cultural commanding heights as never before, with not only academia and the media but also late-night television and sportswriting and even young-adult fiction more monolithically and — to conservatives — oppressively progressive.
