David French of National Review Online explores the ramifications of our American political polarization.

Our national political polarization is by now so well established that the only real debate is over the nature of our cultural, political, and religious conflict. Are we in the midst of a more or less conventional culture war? Are we, as Dennis Prager and others argue, fighting a kind of “cold” civil war? Or are we facing something else entirely?

I’d argue that we face “something else,” and that something else is more akin to the beginning stages of a national divorce than it is to a civil war. This contention rests fundamentally in two trends, one political and the other far beyond politics. The combination of negative polarization and a phenomenon that economist Tyler Cowen calls “matching” is leading to a national separation so profound that Americans may not have the desire to fight to stay together. Unless trends are reversed, red and blue may ultimately bid each other adieu.

First, let’s deal with negative polarization. I’ve written about this before, but it’s worth repeating. Americans tend to belong to their political “tribe” not so much because they love its ideas but rather because they despise their opponents. …

… These trends would be troubling enough, but combine them with “matching” and you get a nation whose citizens increasingly lives separate lives — living in separate locations, enjoying separate media, and holding separate religious beliefs.
