From the beginning of the chapter:
If the various strains of postwar American conservatism were first of all integrated by their common opposition to New Deal liberalism, then one way of getting closer to an understanding of who the conservatives were and how they defined their own political role is to look at how they perceived their liberal counterpart.
Right-wingers objected to New Deal liberalism on a range of different levels. From matters of economic and political theory to moral and spiritual objections, they blamed modern liberalism and the "ethical relativism" that it represented for the impending "Suicide of the West". Although several of these types of objections were usually clustered together, it nevertheless makes sense to separate them for analytical purposes. First, a brief look at how the connotations of the word "liberal" changed with the New Deal.
