“…Earlier work has found that, in general, the quality of representation is better in terms of left vs right ideological preferences, i.e., the main dimension of conflict in European politics, but worse in terms of cultural and European integration dimensions (Costello et al, 2012). National-level research on representation and congru-ence is moving towards the study of single-issue dimensions (see, for example, Rasmussen, Reher, & Toshkov, 2019;Stecker & Tausendpfund, 2016) and some first attempts have been made to study unequal representation across issue-dimensions (e.g., Rosset & Stecker, 2019). Future work on EU-level representation should thus also go beyond the general left-right dimension to examine the EU institutions' congruence with income groups on key policy issues of concern, such as European integration, immigration, and redistribution.…”
