As Matt Yglesias observes, the relative absence of economically liberal social conservative politicians isn’t based on any lack of voters with that set of views. Michael Lind has an interesting take on it in Up From Conservatism. I still don’t know where he got the idea that the number of Americans “who sincerely believe both that abortions should be outlawed and that there should be further massive tax cuts for the rich – is quite small” (maybe he’ll explain it over at TPMCafe). But setting aside Lind’s questionable demographic premises, I think there’s some truth to his argument that the scarcity of politicians who are socially conservative and economically liberal is related to the scarcity of members of the American elite, however defined, who are what Europeans would call “Catholic workers,” libertarians would call “authoritarians,” and Lind would call “national liberals.” Self-identified libertarians, on the other hand, are much better represented amongst the elite than amongst the American public.
