An old but very relevant commentary by Jonathan Rauch:
In his book he comments, seemingly with a shrug, “Some will reject what I have to say as a kind of ‘Big Government’ conservatism.” They sure will. A list of the government interventions that Santorum endorses includes national service, promotion of prison ministries, “individual development accounts,” publicly financed trust funds for children, community-investment incentives, strengthened obscenity enforcement, covenant marriage, assorted tax breaks, economic literacy programs in “every school in America” (his italics), and more. Lots more.
Via David Boaz, who points out Santorum’s explicit rejection of “the whole idea of personal autonomy” and the “idea that people should be left alone.”
