Americans are increasingly choosing to live among like-minded neighbours. This makes the culture war more bitter and politics harderSOME folks in Texas recently decided to start a new community “containing 100% Ron Paul supporters”. Mr Paul is a staunch libertarian and, until recently, a Republican presidential candidate. His most ardent fans are invited to build homesteads in “Paulville”, an empty patch of west Texas. Here, they will be free. Free not to pay “for other people's lifestyles
may not agree with”. And free from the irksome society of those who do not share their love of liberty.
Cynics chuckle, and even Mr Paul sounds unenthusiastic about the Paulville project, in which he had no hand. But his followers' desire to segregate themselves is not unusual. Americans are increasingly forming like-minded clusters. Conservatives are choosing to live near other conservatives, and liberals near liberals.
A good way to measure this is to look at the country's changing electoral geography.

County-level data understate the degree of ideological segregation, reckons Bill Bishop, the author of a gripping new book called “The Big Sort: Why the Clustering of Like-Minded America is Tearing Us Apart”. Counties can be big.
...
Because Americans are so mobile, even a mild preference for living with like-minded neighbours leads over time to severe segregation.
...
Over time, this means Americans are ever less exposed to contrary views. In a book called “Hearing the Other Side”, Diana Mutz of the University of Pennsylvania crunched survey data from 12 countries and found that Americans were the least likely of all to talk about politics with those who disagreed with them.
Intriguingly, the more educated Americans become, the more insular they are.
