From Ross`s op-ed column in the NYT:
Liberals look at the Obama majority and see a coalition bound together by enlightened values — reason rather than superstition, tolerance rather than bigotry, equality rather than hierarchy. But it’s just as easy to see a coalition created by social disintegration and unified by economic fear.
Consider the Hispanic vote. Are Democrats winning Hispanics because they put forward a more welcoming face than Republicans do — one more in keeping with America’s tradition of assimilating migrants yearning to breathe free? Yes, up to a point. But they’re also winning recent immigrants because those immigrants often aren’t assimilating successfully — or worse, are assimilating downward, thanks to rising out-of-wedlock birthrates and high dropout rates. The Democratic edge among Hispanics depends heavily on these darker trends: the weaker that families and communities are, the more necessary government support inevitably seems.
Likewise with the growing number of unmarried Americans, especially unmarried women. Yes, social issues like abortion help explain why these voters lean Democratic. But the more important explanation is that single life is generally more insecure and chaotic than married life, and single life with children — which is now commonplace for women under 30 — is almost impossible to navigate without the support the welfare state provides.
