Nate Silver and Emily McClintock Ekins take a look at how many people have views that could be characterized as economically conservative and socially liberal (whom they label libertarians) or the reverse (whom they label “hardhats” or communitarians). All of their measures find conservatives and liberals are the two largest groups, but roughly 40 percent of the population falls into one of the other two categories. Both of these groups are underrepresented in American politics — especially, it seems to me, the hardhats.
