Political parties, interest groups, and unequal class influence in american policy

Abstract

Do policy makers in both parties represent the opinions of the richest Americans, ignoring those of median income? We find that the two political parties primarily represent different interest group sectors, rather than public economic classes. The Republican Party and business interests are aligned across all issue areas and are more often aligned with the opinions of the richest Americans (especially on economic policy). Democrats more often represent middle class opinions and are uniformly aligned with advocacy groups. Support from both parties is associated with policy adoption, but party influence cannot explain the association between affluent opinions and policy outcomes. Rather than an oligarchic political system, these patterns show competition among organized elites that still provides multiple potential paths for unequal public class influence.
