A combination of political and economic forces have helped to return the states to the centre of the political stage. Whether measured by objective indicators (employment, share of government expenditure, elasticity of state revenues) or political institutional changes (the rise of career governors, the increasing influence of the intergovernmental lobby and the spread of state responsibilities), the states have become increasingly important in the formulation and implementation of American domestic policies. However, these changes have by no means reduced the level of intergovernmental conflict. On the contrary, cuts in federal expenditure, the introduction of block grants and public opposition to increases in state and local taxation are likely to intensify debate on distributional questions at the state level.
