David Brooks has called Santorum a working class conservative, a Volokh post a big gubmint conservative. It was interesting to see him cite his grandfather's leaving Italy in the 20's when Mussolini came to power as to my not real informed speculation Mussolini was also a big gubmint conservative in a way; probably just went a tad far for the pops. Anyway, Santorum is kind of a Catholic Social Welfare kind of conservative apparently; so at least in a religious social sense it's nice that the evangelicals would have him. It's interesting how Iowa broke - quite polar with Santorum and Ron Paul, the latter a simplistic libertarian true enough but also simplistic enough to be anti-libertarian also.
