Not so responsive after all: European parties do not respond to public opinion shifts across multiple issue dimensions

Many studies have found that European parties change their policy positions in response to changes in public opinion. This is both theoretically and normatively appealing, suggesting that European party politics operates in a way that is consistent with spatial models. Nonetheless, virtually all previous studies are based on a single, uni-dimensional measure of public opinion: left–right self-placement from the Eurobarometer surveys. This measure has a number of flaws, including the fact that political conflict in Europe now occurs across multiple issue dimensions beyond the classic divide on state involvement in the economy. We used new measures of Europeans’ ideological positions across four different issue dimensions and 26 countries from 1981–2016, together with data on parties’ policy positions from their manifestos, to re-evaluate findings on responsiveness. Across many different model specifications, samples and outcome measures, we found virtually no evidence that European political parties respond to public opinion on any issue dimension. Our findings suggest that scholars may require better measures of party positions, more nuanced theories of responsiveness (for example to sub-groups, or across longer time horizons), or may need to refocus their attention towards responsiveness via policy outcomes rather than parties’ policy commitments

The Causal Effect of Radical Right Success on Mainstream Parties' Policy Positions: A Regression Discontinuity Approach

This article investigates how the success of radical right parties affects the policy positions of mainstream parties. We do this using a regression discontinuity approach that allows us to causally attribute mainstream parties’ positional changes to radical right strength independent of public opinion as a potential confounder. Making use of exogenous variation created through differences in electoral thresholds, we empirically demonstrate that radical right success, indeed, causally affects mainstream parties’ positions. This is true for mainstream left as well as mainstream right parties. These findings make an important contribution to the broader literature on party competition as they indicate that other parties’ behavior and not only public opinion plays a crucial role in explaining parties’ policy shift

Radical right success and mainstream parties’ anti-immigrant policy shifts

Radical right parties have seen increasing electoral success throughout Europe. What does this imply for parties and party systems? Do established mainstream parties adjust their policy positions in response to successful radical right parties? If yes, is this ‘contagious effect’ restricted to specific party families or is this an overall trend within European politics? Tarik Abou-Chadi and Werner Krause investigate these questions and find that mainstream parties adjust their policy strategies when confronted with a successful radical right challenger and shift toward more anti-immigrant positions. Using a novel research design, they can demonstrate that these shifts are not just a response to changing public opinion but can be causally attributed to the success of the radical right
