Ideal points of MPs in the UK House of Commons (HoC) are characteristically difficult to ascertain due to tight party discipline and strategic voting by opposition members. This research note generates left/right ideal point estimates for 591 British MPs sitting in the HoC as of 22/08/2022, ascertained through their social media followership. Specifically, estimates are derived by conducting correspondence analysis (CA) on MP Twitter (X) follower networks, which are subsequently validated against an expert survey, confirming that these estimates have a high degree of between-party (R2 = 0.93) and within-party (Con: r = 0.84; Lab: r = 0.81) accuracy. The informative value of these estimates is then demonstrated by predicting candidate endorsement in the September 2022 Conservative leadership contest, confirming that an MP's ideal point was a statistically significant predictor of candidate endorsement, with Liz Truss drawing support primarily from the further right of the party.

Traditional research on political parties pays little attention to the temporal focus of communication. It usually concentrates on promises, issue attention, and policy positions. This lack of scholarly attention is surprising, given that voters respond to nostalgic rhetoric and may even adjust issue positions when policy is framed in nostalgic terms. This article presents a novel dataset, PolNos, which contains six text-based measures of nostalgic rhetoric in 1,648 party manifestos across 24 European democracies from 1946 to 2018. The measures combine dictionaries, word embeddings, sentiment approaches, and supervised machine learning. Our analysis yields a consistent result: nostalgia is most prevalent in manifestos of culturally conservative parties, notably Christian democratic, nationalist, and radical right parties. However, substantial variation remains regarding regional differences and whether nostalgia concerns the economy or culture. We discuss the implications and use of our dataset for studying political parties, party competition, and elections.

Social democratic parties have experienced considerable electoral decline recently, which has often been attributed to their rightward policy movement. This paper advances this literature by examining who benefits from this moderation strategy and who is abandoning the social democrats. It does so by analyzing aggregate-level election results and individual-level Comparative Study of Electoral Systems data, on a sample of 21 advanced democracies, over 327 elections, from 1965 to 2019. I find little support for the assertion that social democrats are defecting to one party. However, in agreement with the spatial theory of party competition, results reveal that the radical left increasingly and significantly benefit from social democratic economic rightward positions, which is magnified when combined with rightward sociocultural positions. This predominantly occurs because left-leaning voters migrate to the radical left. The findings provide notable ramifications for party strategy and contribute to explanations for the rise of challenger parties, at the expense of mainstream parties.

When mainstream parties accommodate radical-right parties, do citizens grow more concerned about immigration? Based on a rich literature, we argue that challenger parties’ ability to affect mainstream party positions, particularly on immigration, is associated with greater public salience of immigration and voter positivity towards challengers exists. We use Comparative Manifesto Project and Comparative Study of Electoral Systems data in order to show that challenger issue entrepreneurship, and mainstream accommodation are associated with greater public concern for challenger issues. These factors do not result in greater public positivity towards challengers. Our findings thus support the argument that a mainstream party accommodative strategy might not be as beneficial for them as often expected by pundit and political scientists alike. This has implications for understanding the effect of indirect party strategies on public attitudes, since mainstream accommodation changes public concern regarding issues, which may bolster challengers’ positions, including radical-right parties.

In 2009, after decades of single party rule under the Liberal Democratic Party (LDP), Japan had its first taste of a real alteration of power. However, just 3 years later, the LDP regained control of government with no significant challenger in sight. Historically, LDP dominance is a common tale, but its resurgence in recent years poses a significant puzzle in Japanese politics. What exactly has contributed to the LDP's return to power? In the years that have passed, the LDP's strength has come from a combination of cash, clientelistic networks, and strong candidates, but recent research has found that Japanese politics has become more programmatic and party-focused. While LDP dominance since its return to power in 2012 can be attributed in part to its candidates, I find that the appeal of the party label has played a large role in securing the LDP's large majorities.

In recent decades, there has been an institutional shift in the literature on authoritarian regimes, with scholars investigating the role of political institutions, such as elections and political parties, in shaping regime stability and economic performance. However, scant attention has been devoted to the effect of political institutions on policy outcomes, and more specifically, on income inequality. This paper adds to this debate and sheds light on the role of formal and informal institutions, on the one hand, and state capacity, on the other, in influencing levels of income inequality in autocracies. We argue that, while the presence of elections and multiparty competition creates more favourable conditions for the adoption of redistributive policies, state capacity increases the likelihood of successfully implemented policy decisions aimed at reducing the level of inequality. Our empirical analysis rests on a time-series cross-sectional dataset, which includes around 100 countries from 1972 to 2014. The findings indicate that both political institutions and a higher level of state capacity lead to lower levels of income inequality in authoritarian contexts.

The electoral district is the fundamental unit of representation in single- and multi-member electoral systems, yet most research shows little interest in district effects on election outcomes, focusing instead on national and individual factors. This is problematic as parties and candidates often put a great deal of effort into district-based campaigns. How, then, can we best capture district effects on party support? We propose a new method using official election returns and geospatial techniques. The result is a measure of how much of a party's vote share is explained by district effects. Using data from the 2006–2019 Canadian federal elections, we find that, on average, 6 to 10 per cent of the variation in a party's vote in Canada is explained by district effects. While district effects on party support are trivial for some districts, in others they account for more than 80 per cent of the variance in party vote shares. The effect of districts on party support is composed, in part, of electoral context, province, socio-economic factors and district campaign intensity. Importantly, the size and sources of district effects on party support vary across parties, suggesting heterogeneity. The benefits of our approach are threefold: (1) it is cost-effective, (2) it can be easily replicated in any setting—past or present—where districts are relevant electoral units and where districting is nonpartisan, and (3) it is responsive to differences in district composition and parties’ campaign effort.

While the structure of party competition evolves slowly, crisis-like events can induce short-term change to the political agenda. This may be facilitated by challenger parties who might benefit from increased attention to issues they own. We study the dynamic of such shifts through mainstream parties’ response to the 2015 refugee crisis, which strongly affected public debate and election outcomes across Europe. Specifically, we analyse how parties changed their issue emphasis and positions regarding immigration before, during, and after the refugee crisis. Our study is based on a corpus of 120,000 press releases between 2013 and 2017 from Austria, Germany, and Switzerland. We identify immigration-related press releases using a novel dictionary and estimate party positions. The resulting monthly salience and positions measures allow for studying changes in close time-intervals, providing crucial detail for disentangling the impact of the crisis itself and the contribution of right-wing parties. While we provide evidence that attention to immigration increased drastically for all parties during the crisis, radical right parties drove the attention of mainstream parties. However, the attention of mainstream parties to immigration decreased toward the end of the refugee crisis and there is limited evidence of parties accommodating the positions of the radical right.

This article aims to explain the variation in the electoral support for extreme-right parties (ERPs) in Europe. The extant literature on the far-right party family does not answer this question specifically with regard to the extreme-right variants for two main reasons. Firstly, theories did not expect the electoral success of these parties in post-war Europe due to their anti-democratic profiles and association with fascism. Secondly, despite the fact that they acknowledge the differences between the parties under the far-right umbrella – namely, the extreme and the radical – they normally do not take these differences into account, and if so, they focus on the radical-right parties. This article shows that electoral support for ERPs is associated with low quality of government and highly conservative mainstream-right parties. The former creates political legitimization for anti-democratic parties and the latter ideological normalization of extreme right.

Using Voting Advice Application (VAA) data from the EU Profiler/euandi Trend File, we studied how parties’ positions towards European integration relate to their positions on other important issues, and how this varies across EP elections, and between European regions. We hypothesized that the association between parties’ EU-integration positions and their positions on other issues was affected by the three major crises that hit the European Union (EU) between 2009 and 2019: the economic, migration, and climate crises. Additionally, we hypothesized that the economic and migration crises asymmetrically affected the association between cultural and economic issues on the one hand and the EU dimension on the other across the EU’s three macro regions (NWE, SE, and CEE). Our results show that neither the economic crisis nor the migration crisis or the climate crisis had an EU-wide impact on how European integration relates to other issue dimensions. As we hypothesized, economic issues were particularly strongly linked to EU-integration positions in SE in 2014, but our results additionally indicated that the longstanding interpretation of EU integration as a mainly economic issue in SE diminished after the start of the migration crisis. Finally, EU integration became related to immigration issues in CEE while this is not the case in the other regions. The main takeaway is that EU integration is interpreted differently by parties across the EU, which is important to recognize for parties that seek to work together in transnational party groups, and for scholars that aim to understand EU policy making.

Inspired by Lipset and Rokkan, the field of political science has primarily focused on party oppositions as a derivative of historically anchored conflicts among social groups. Yet parties are not mere social mirrors; they are also active interpreters of social context. In a globalized era they deploy conflicting frames on how solidarity may be preserved, as recent work on populist welfare chauvinism shows. However, the role of party political agency in framing solidarity lacks an overarching framework. This article therefore proposes a Durkheimian model that takes the integrative pole of the conflict–integration dialectic seriously and distinguishes among group-based, compassionate, exchange-based and empathic frames. The authors test this solidarity framework in Flanders (Belgium) – a good case study due to its fragmented party system and increasing economic and cultural openness. The content analyses of party manifestos presented here suggest that a solidarity-based deductive approach to studying partisan competition is relevant because partisan differentiation along solidarity lines is growing; this evolution converges with similar inductive expert-based and issue-based findings.

Despite the sweeping societal and economic transformation brought about by digitization, it has remained a relatively marginal topic in elections, with parties having few incentives to signal commitment to digitization. Why then would parties start to do so? We address this question by examining party manifestos from German subnational elections in the period between 2010 and 2018. Our analysis contributes to the research on issue competition by looking at why parties engage with the topic of the digitization even though it has neither become politicized nor salient, at present. We find, first, that parties emphasize digitization more in regions belonging to the mid-tier in terms of their degree of digital modernization. Second, parties with more resources and greater ideological compatibility signal more commitment to digitization. Finally, electoral success of the Pirate Party as a credible challenger has been followed by greater emphasis on digitization, especially among the ideologically closest competitors.

During the economic crisis, the radical left, especially in countries of the European South, continued its course from marginality to mainstream while social democracy found itself trapped in its previous strategic orientations. This article examines the two political families in a relational and comparative perspective, focusing on the interaction of social democratic and radical left parties that evolved in a series of national cases (Greece, Portugal, Spain and France) and in particular within the political and electoral cycle of 2015–17. The ideological, programmatic and strategic responses of these parties to the critical juncture of the crisis, which mark a convergence or deviation in the paths of the two ‘enemy brothers', shed light on their political and ideological mutations, transformations and/or adaptations.
