In this article, we explore the consequences of the increasing presence of both left- and right-wing populist parties in government, critically reflecting on the recent scholarship on the topic, underlining promising venues for future research and outlining a conceptual framework which constitutes the background of this special issue entitled ‘Populism in Power and its Consequences’. Our main contribution is empirical, since – by reflecting on the various articles hosted in the special issue – we assess the impact of populist parties in government on politics, polities and various policy domains. We also provide an account of potential moderating factors of the influence of populists in government, focus on different ideological underpinnings of types of populisms (left-wing and right-wing) and discuss their relevance. We conclude by identifying four possible scenarios for European populist parties in governments: radicalization, compromise and moderation, splintering, or loss.

This article argues that the relationship between capitalism and democracy is not immutable but subject to changes over time best understood as movements across distinctive growth and representation regimes. Growth regimes are the institutionalized practices central to how a country secures economic prosperity based on complementary sets of firm strategies and government policies. Representation regimes reflect conditions in the arenas of electoral and producer group politics that confer influence on specific segments of the population. The emphasis is on how economic experiences and changes in the structure of electoral cleavages alter the terms of political contestation, thereby giving voice to specific sets of interests and altering the balance of influence between capitalism and democracy. The analysis examines how the growth and representation regimes of the developed democracies have changed through three post-war eras to yield distinctive distributive outcomes in each era.

This article investigates the dimension and evolution of the financing of political parties. It focuses on 28 parties in the five major European countries (Germany, France, UK, Italy, Spain), analysing the parties’ budgets from 2002 to 2016. The article's assessment shows that the availability of funds increased until the beginning of the Great Recession (2008), and then decreased, mainly due to a decline in public support for parties. Diminished state generosity has led parties to look for different sources of financing: the article shows the proportion of self-funding resources in terms of membership fees and private donations that has sustained the parties’ finances. Finally the article presents a model that helps to explain the shrinking of parties’ income by including parties’ ideological alignment, electoral outcome, presence in government and share of public financing, and countries’ public spending and GDP level, to investigate the plausible causes of the reduction of parties’ income.

How does a political party become ‘mainstream’? And what makes some parties receive arguably the opposite designation – ‘pariah party’? This conceptual article examines the processes by which parties’ mainstream or pariah status must be constructed, negotiated and policed, not only by political scientists in the pursuit of case selection, but by several actors actively involved in the political process, including media actors and political parties themselves. It explains how these actors contribute to these processes of ‘mainstreaming’ and ‘pariahing’, considers their motivations and provides illustrative examples of how such processes take place. As such, the article moves beyond the literature on the ways in which mainstream parties seek to deal with or respond to threats from a variety of pariah parties, instead paying attention to how those parties have been constructed as pariahs in the first place, and how these processes simultaneously contribute to the maintenance of mainstream party identities.

In this article, we focus on the candidate selection processes of Podemos in Spain and the Movimento 5 Stelle (M5S – Five Star Movement) in Italy, processes which are related to intra-party democracy. With a mixed-methods approach (including novel data from the expert survey PoPES, 31 semi-structured interviews with party representatives and militants, and analysis of party documents, statutes and leader speeches) and a comparative perspective, we explore candidate selection in the context of the broader organizational party structures over time. We find that: (1) Podemos functions like a typical centralized party, whereas M5S is a deviant case with strong and centralized control over party organization but decentralized mechanisms for candidate selection; (2) both these logics of centralization of power undermine the parties’ democratic credentials but have different consequences in terms of cohesion (expulsions/departures in M5S and splintering in Podemos); and (3) in both cases, the parties’ organizational culture and symbolic tools legitimate their top-down features.

European mainstream right parties are increasingly choosing to include radical right parties in coalition governments or other types of stable and committed cooperation. How does this cooperation affect voters’ perceptions of party positions? This article examines whether coalition signals have a significant impact on voters’ perceptions of the specific policy issues that were at stake in the bargaining process. More specifically, does the issue ownership of the radical right cause voters to perceive mainstream parties as radicalizing on immigration issues pertaining to asylum and multiculturalism? I compare the perceptions of Dutch parties before and after two coalition formations that (formally and informally) involved a radical right party: the coalition with the List Pim Fortuyn in 2002 and the support agreement with the Freedom Party in 2010. Furthermore, I examine the long-term effects of the Danish mainstream right government's reliance on the support of the radical right Danish People's Party in 2001–11.

Recent discussions of accountability in contexts of expert knowledge raise questions about the limits of transparency. Against this background, we discuss the nexus between expert knowledge and meaningful accountability – that is, context-sensitive accountability based on a genuine understanding of a situation. We argue that the concentration of expertise in certain institutions makes it difficult to hold those institutions accountable. In particular, three components challenge meaningful accountability: specialization, inaccessibility and potential biases or conflict of interest. We emphasize the role of ‘epistemic communities’ and their impact on the tension between expert knowledge and independence. Drawing on the deliberative systems literature, we discuss how expert knowledge might be communicated to outsiders to enable meaningful accountability. To illustrate our argument, we draw on the European Central Bank, a case study in which states have chosen a delegation design characterized by a high degree of independence and trust in expert knowledge, to the detriment of accountability. We sketch possible avenues for creating the conditions for meaningful accountability even in the case of institutions with highly concentrated expertise.

Scholars have long debated whether populism harms or improves the quality of democracy. This article contributes to this debate by focusing on the impact of populist parties in government. In particular, it inquires: (1) whether populists in government are more likely than non-populists to negatively affect the quality of democracies; (2) whether the role of populists in government matters; and (3) which type of populism is expected to negatively affect the quality of liberal-democratic regimes. The results find strong evidence that the role of populists in government affects several qualities of democracy. While robust, the findings related to (2) are less clear-cut than those pertaining to (1). Finally, regardless of their role in government, different types of populism have different impacts on the qualities of democracy. The results show that exclusionary populist parties in government tend to have more of a negative impact than other forms of populism.

Our aim in this article is to show the stance on solidarity present in a hybrid regime. Taking Hungary as an example, we give individual-level explanations for attitudes towards solidarity and inclusion/exclusion in times when populist parties are in power. By creating typical solidarity groups, we explain who belongs to different solidarity clusters and why, what political orientations can be linked to solidarity groups and whether people's attitudes reflect the values/solidarity conceptions propagated by the Orbán government. With this, we point to the social and political polarization of Hungarian society. We found that the appreciated, satisfied and politically trustful far-right exclusive groups – independent of their social status – make up not only the majority of society but also the crucial system-justifying basis of the Orbán regime. However, in an ethnically rather homogeneous society foreigners could be seen as cultural and economic threats to the decisive majority, including a significant part of the inclusive groups.

The Arab Spring revived interest into how contentious mobilization diffuses across time and space. We evaluate individual-level attitudinal implications of this literature through laboratory experiments with 681 Egyptian college students. Across two separate experiments, primes based on recent protests in Tunisia, Syria and the Sudan reveal a limited ability to shift respondents’ retrospective views of the Arab Spring, the efficacy of protest to achieve political change, Egypt's perceived domestic situation vis-à-vis its neighbours and a personal willingness to assume risk in a computer game-based behavioural extension. Our findings imply the need to continue to improve theorizing and empirically testing key implications from the diffusion literature.

What happens after primary elections? Strategies of loyalty or defection in general elections have been addressed by US literature mainly by means of aggregate data. However, we lack similar studies in non-US contexts. This article investigates the strategies followed after primary elections by taking the case of the Italian Partito Democratico as an illustration. We addressed the individual drivers of loyalty or defection strategies by considering three different dimensions: (1) the outcome of the primary election, having backed a winning or losing candidate; (2) the strength of partisanship, meant as ideological congruence with the party and partisan involvement; and (3) the leader effect. We relied on four surveys (exit polls) administered during party leadership selections held in 2009, 2013, 2017 and 2019. The results suggest that all three dimensions have an influence on post-primary strategies, but what counts the most is partisan involvement.

This article investigates three explanations for electoral support for the far right – ‘cultural backlash’, ‘economic grievances’ and ‘protest voting’ – in a novel way. Our main contribution is that we contrast far-right voters with voters of centre-right parties, traditional left-wing parties and abstainers. Equally innovative is the comparison between mature and post-communist democracies. Using European Social Survey data (2014–16), we conclude that anti-immigration attitudes are most important in distinguishing far-right voters from all other groups. Yet, these differences are significantly smaller in Eastern Europe. Furthermore, far-right voters are not the so-called socioeconomic ‘losers of globalization’: this is only true when compared with centre-right voters. Concerning protest voting, distrust of supranational governance particularly enhances far-right voting. Overall, our study concludes that more fine-grained distinctions pay off and avoid misleading generalizations about ‘European far-right voters’ often presented in public debates.

Studies have suggested that people voting for Brexit were motivated by anti-globalization, anti-multiculturalism and anti-elite sentiments. However, little is known about how these factors are related and whether citizens in other member states share similar reasons for wanting to exit the EU. Methodologically, this question is addressed by utilizing path models on data from the European Social Survey, with respondents in 17 countries. Empirically, this article reveals considerable cross-country variation, which implies that motivations for voting Leave should be assessed on a country-by-country basis. Yet, two main pathways are identified. First, lower education is related to more negative attitudes towards multiculturalism, which increases the probability of voting Leave. Second, lower income decreases the level of trust in the political establishment, which again increases the probability of voting Leave. Theoretically, this implies that the anti-globalization model is subsumed by the anti-multiculturalism and anti-elite models, giving rise to two new mechanisms.

Despite increasing research into populist parties in power, their impact on subnational institutions has been neglected. Taking a novel multilevel perspective, this article inquires into the policy consequences of populist radical right parties (specifically, the FPÖ and Lega) in local government, and the effect of their simultaneous participation in national government. The article shows the expansion of exclusionary policy that follows their concurrent presence in national and local government. The process that leads from national government entry to local policy influence is traced using interview and newspaper data. The article argues that the influence of central parties over these ‘showcase’ localities is rooted in different multilevel governance configurations. These vary cross-nationally according to two factors: the strength of mayors’ linkages with higher government levels in the different institutional settings and, due to the different extent of party nationalization, the strategic value of the municipality to the central party.

We have limited knowledge of how the insecure environment characteristic of personalist dictatorships affects the behaviour of provincial leaders. In this article, we argue that such provincial leaders face a trade-off: either they can keep a low profile but remain vulnerable to the capriciousness of the ruler (the acquiescent strategy), or they can gamble and try to build a power base of their own as a defence against the whims of the dictator (the power-accruing strategy). Next, we specify three contextual conditions, each of which makes provincial leaders more likely to choose and succeed with a power-accruing strategy, which in turn allows them to rule their province with an iron fist. Finally, empirically, we illustrate our arguments through a number of example cases and an in-depth study of a contemporary, very powerful provincial leader in a personalist authoritarian regime: Ramzan Kadyrov, leader of the Chechen Republic within Vladimir Putin's Russia.

Do the class backgrounds of legislators shape their views and actions relating to inequality and economic policy? Building on findings about ‘white-collar government’ in the US, this article examines the relationship between legislators’ class and their attitudes and self-reported behaviour in advanced democracies, drawing on survey data from 15 countries including 73 national and subnational parliaments in Europe and Israel. I find that legislators from business backgrounds are more likely to support income inequality and small government, as well as less likely to consult with labour groups, than those from working-class and other backgrounds. These results are buttressed by analysis of an additional cross-national survey of European legislative candidates’ attitudes, which replicates key findings. Given the skewed class makeup of legislatures in advanced democracies, these findings may be relevant to our understanding of widespread economic and political inequalities that are increasingly salient in many countries.

Although the research surrounding PRR parties has increased over the years, health policies, an important part of the welfare system, have generally been neglected. Using an in-depth case-study approach, this article analyses the health policy consequences of PRR parties in Austrian and Italian subnational governments over time, thereby expanding the units of analysis while also looking at an understudied level of government. The findings indicate a propensity towards neoliberalism, combined with accents of welfare chauvinism in Austria and a strategy of shutting down the Freedom Party of Austria. In the case of Italy, both regional cases mark a desire for welfare chauvinism but an inability to restrict healthcare access directly. In all four cases (except Burgenland), the PRR parties are consistently chauvinistic (despite seeming to prefer welfare to liberal chauvinism, they typically implement the latter for health policies) and any factor of generosity comes from a social democratic coalition partner or not at all.

Recently several populist parties have become part of coalition governments in multiparty democracies, specifically in Western Europe. Based on the inclusion-moderation thesis, academics assume that incumbent populist parties tone down their populist rhetoric as a result of the daily businesses of deliberation and compromises in coalitions. However, while the assumption of tamed populists in power is widespread, there is little empirical work dealing with the topic. Using a classical quantitative content analysis of 1,210 Facebook posts published by populist parties in Italy, Spain, Austria and New Zealand, this article examines whether opposition parties are more populist and nativist than those in coalition governments. The findings indicate that populists do not decrease the degree of anti-elite and people-centred messages when they are in power but rather change the type of elites they attack and the antagonist groups they juxtapose. We should therefore rethink the validity of the inclusion-moderation thesis for populist parties in coalition governments.

In this article, we introduce a unique data set containing all written communication published by the German Bundestag between 1949 and 2017. Increasing numbers of scholars make use of protocols of parliamentary speeches, parliamentary questions or the texts of legislative drafts in various fields of comparative politics including representation, responsiveness, professionalization and political careers or parliamentary agenda studies. Since preparing parliamentary documents is rather resource intensive, these studies remain limited to single points in time, types of documents and/or policy areas. The long time horizon and various types of documents covered by our new comprehensive data set will enable scholars interested in parliaments, parties and representatives to answer various innovative research questions related to legislative studies.

Bridging the literature on gender and politics, democratization, and political parties, this article investigates the causes of parties’ varying compliance with electoral quotas. Whereas research has so far focused on parties’ willingness to comply, this article sheds light on their ability to do so. It suggests that the more quotas parties have to comply with, and the more complex the quotas’ designs, the more difficult implementation becomes for the organizationally weak parties that we often encounter in new democracies. The argument is developed and substantiated in a comparative analysis of parties’ quota compliance in the 2018 Tunisian local elections. Although the Islamist party was able to comply fully with all quotas (for women, youth and people with disabilities), small secular parties lost a number of lists and state funding due to non-compliance. While the quotas were highly effective in securing group representation, they had repercussions on party and party system consolidation.
