Responsiveness when parties are “weak”: A candidate-based analysis of voter-party congruence in Europe

Outside the US, the crucial question of how well politicians represent the preferences of voters is usually investigated at the party level. Reversing this perspective, we examine representation in Europe from the point of view of individual candidates running in national parliamentary elections. This is especially insightful in a period that seems characterized by a decline in parties’ representational capacities and an increasing personalization of politics. We analyze representation by considering the incongruence between candidates’ left–right positions and the average placement of their party voters. By combining candidate survey data with mass survey data on voters, we assess how ideological incongruence varies according to predictors measured at the levels of candidates, parties, and party systems. The results highlight a systematic association between a partisan style of representation and candidates’ proximity to voters, as well as the interactions between representational roles and factors such as the anti-establishment nature of parties and ideological polarization in the party system.
