George Will, ostensibly commenting on the viability of the current Republican contenders reveals more about himself than he does the race for the nomination. This is the best/worst defense of Santorum I have heard.

The problem is not that the phenomena that trouble Santorum are unserious. The use of prenatal testing for search-and-destroy missions against Down syndrome and other handicapped babies is barbaric. Obama’s stealthy pursuit of a national curriculum for grades K through 12 is ill-advised and illegal. And no domestic problem — not even the unsustainable entitlement state — is more urgent and intractable than that of family disintegration.

The entitlement state can be reformed by various known — if currently politically impossible — policy choices. But no one really knows the causes of family disintegration, so it is unclear whether those causes can be combated by government measures.

We do know the social pathologies flowing from the fact that now more than 50 percent of all babies born to women under age 30 are born to unmarried mothers. These pathologies, related to a constantly renewed cohort of adolescent males without fathers at home, include disorderly neighborhoods, schools that cannot teach, mass incarceration and the intergenerational transmission of poverty. We do not know how to address this with government policies, even though the nation has worried about it for almost 50 years.

He is an engagingly happy warrior, except when he is not. Then he is an angry prophet of a dystopian future in which, he has warned, people will be “holed up in their homes afraid to go outside at night.” He has the right forebodings but may have the wrong profession. Presidential candidates do not thrive as apostles of social regeneration; they are expected to be as sunny as Ronald Reagan was as he assured voters that they were as virtuous as their government was tedious.

Today’s Republican contest has become a binary choice between two similarly miscast candidates. Romney cannot convince voters he understands the difference between business and politics, between being a CEO and the president. To bring economic rationality to an underperforming economic entity requires understanding a market segment. To bring confidence to a discouraged nation requires celebrating its history and sketching an inspiring destiny this history has presaged.

Romney is right about the futility of many current policies, but being offended by irrationality is insufficient. Santorum is right to be alarmed by many cultural trends, but implies that religion must be the nexus between politics and cultural reform. Romney is not attracting people who want rationality leavened by romance. Santorum is repelling people who want politics unmediated by theology. Neither Romney nor Santorum looks like a formidable candidate for November.

Translation. I know Santorum is right and I know the other guy doesn’t get it and won’t fix a doggone thing, but looking smart to the sneering class seems more important to me right now, after all, my livelihood depends on it.
