Political Parties, Public Opinion, and State Policy in the United States

Abstract

When comparing states in the United States, one finds little correlation between state opinion and party control of the state legislature or between party control and state policy. Although these low correlations seeming to indicate that partisan politics is irrelevant to the representation process, the opposite is true. State opinion influences the ideological positions of state parties, and parties' responsiveness to state opinion helps to determine their electoral success. Moreover, parties move toward the center once in office. For these reasons, state electoral politics is largely responsible for the correlation between state opinion and state policy.
