In America politics is more and more a matter of social metaphysics:
- If your position and beliefs incline you to believe that the social world is horizontal and self-contained, and consists solely of the individual and various contractual and legal collectives (e.g., if you’re single, godless, a celebrity, an elite lawyer or financier, or an ecclesiastical modernist who’d like to do away with the transcendent), you’re likely to be liberal and vote Democratic.
- If you’re inclined to believe the contrary—that the social world is complex in the sense that it is composed of several very different sorts of things that are dependent on a larger setting and so can’t be managed easily—you’re much more likely to be conservative and vote Republican.
That difference in fundamental understanding swamps all other issues. To choose a couple of data points from the items linked above, in the last presidential election the God gap was about 27 points, and in this one it looks like single vs. married is likely to make a 16-point difference in the men’s vote and a 38-point difference in the women’s vote.
