The Sage of Mt. Airy reminds us what's really wrong with Gingrich's opportunistic attack on Paul Ryan:  as a deprivation of liberty, social engineering is by definition left-wing.  Moreover:

Use of the phrase belies a fundamental belief that what currently divides our country can be adequately captured on some continuum of thought, left to right.  But that notion itself belies an even more fundamental belief that, actually, nothing divides our country, that it's all a matter of degree.  The modern, nanny-state leviathan is the norm; we're only arguing about more or less, (Always privileging "more", of course.)
