“Rebuilding the American State” was written in the manner of a bozzetto: it is a sketch drawn to reshape interlocking analytical and historiographical conversations and to suggest pathways joining the era of Roosevelt to the qualities and conundrums of postwar Democratic party liberalism. We underscored the key role of what might be called the long 1940s, stretching from the economic and political crisis faced by the New Deal in 1937–38 to the election in 1952 of the first Republican president since Hoover. We claimed that institutional and policy decisions taken across a number of domains in this period coherently recast the state and, in so doing, the contours and possibilities of American politics. We argued as well that old and new institutionalist approaches to state capacity have shared an unfortunate propensity to inventory organizational resources without regard to the normative and practical policy visions that define the content of what it is the state actually is meant to accomplish. In this light, simple dichotomous distinctions between weak and strong states appear as too blunt to sharply etch our understanding of the past half-century of American political development.
