Multi-level legislative representation in an inchoate party system: Mass-elite ideological congruence in Brazil

Abstract

Research has suggested that fragmented political systems, incohesive parties, and weak programmatic links between voters and legislators can undermine the effectiveness of ideological legislative representation. Using Brazil's national and state assemblies, we examine the potential for voter-elite congruence in a legislative environment considered weak in programmatic representation and highly fragmented by a decentralized political structure. Focusing on 2005–2014, we use mass and elite survey data from the National Congress and 12 state assemblies to estimate deputies' and respondents' ideal points on a common left-right scale. Despite many potential barriers to ideological representation, we find an aggregate pattern of congruence between voters' and politicians' ideological positions during this period, with stronger voter-deputy correspondence for state deputies on average. These patterns are confirmed by a dyadic analysis of deputy and voter characteristics. However, we also find weaknesses in party-level ideological congruence for the major parties—for voters on the left and party supporters on the right. The findings suggest that, while the party system did not prevent overall ideological representation, it may have hindered important aspects of party representation.
