The correspondence between public preferences and public policy is acritical rationale for representative democratic government. Thisview has been put forward in the theoretical literature on democracyand representation (e.g., Dahl 1971;Pitkin 1967; Birch 1971) and in “functional” theories of democraticpolitics (Easton 1965; Deutsch 1963), both of which emphasize theimportance of popular control of policymaking institutions.Political science research also shows a good amount ofcorrespondence between opinion and policy, though to varyingdegrees, across a range of policy domains and political institutionsin the U.S. and elsewhere. This is of obvious significance.Earlier versions of this paper werepresented at the 2006 Annual Meetings of the American PoliticalScience Association, Philadelphia, at the Elections, PublicOpinion and Parties specialist group, Nottingham, England, andat the 2007 National Conference of the Midwest Political ScienceAssociation, Chicago.
