Abstract
The growth of the public sector in recent years has been accompanied by both centralization and decentralization. More important than any such shifts of power or function between levels of government, however, has been the emergence of new arenas of mutual influence among levels of government. In this way recent developments in intergovernmental relations are adding a new dimension to the national system of representation. That the federal division of powers should serve a representative function is entirely in accord with the original design. A look at this design in the light of the theory of its founders helps one perceive this distinctive purpose. Then as now American federalism was primarily an instrument of national democracy. Current American experience with this aspect of intergovernmental relations, moreover, suggests questions for comparative study of the contemporary welfare state.
