Partidismo negativo, derecha radical y voto: un análisis de su relación en el contexto de las elecciones generales españolas de 2023

Public support for the <i>cordon sanitaire</i> : Descriptive evidence from Spain

Reactions to the rise of far-right parties that advocate democratic backsliding, and the dilution of socially liberal democratic norms present a dilemma for existing political parties. How should existing political parties respond to this challenge? A commonly adopted strategy is to apply a cordon sanitaire which excludes radical right-wing challengers from the government-forming process. Do voters support this policy? Leveraging data from Spain – where the mainstream right has accommodated the radical right-wing party, VOX, via numerous governing coalitions – I rely on individual citizens’ views on how parties should respond to rise of the far-right party, to answer this question. Empirically, the results show very low-level support for the cordon sanitaire in Spain. Indeed, the modal position of the electorate, regardless of their ideological position, is to treat the party just like any other. These results are not conditioned by the propensity of individuals to identify VOX as indeed being a “radical right” party. These descriptive findings suggest that whilst radical right-wing parties may present an inimical threat to democratic norms, citizens do not necessarily view the means of squashing this threat to be one of strategic exclusion. This likely explains why the mainstream right has been able to institutionalise VOX as a political ally: where strategic exclusion is not expected, the mainstream right need not fear violating an expectation that does not exist.

Recuerdo de voto y distorsiones analíticas: el caso español tras las elecciones generales de 2023

The objective of this research is to analyze and identify patterns in the variables of vote recall and vote intention as recorded in the monthly barometers conducted by the Spanish Center for Sociological Research (CIS). The methodological approach employed is time series analysis. The empirical findings indicate that the average percentage of vote recall for the progressive parties, PSOE and Sumar, does not differ from their results in the most recent general elections. In contrast, the percentages for the PP and Vox are lower than their actual electoral outcomes. The study confirms the presence of vote concealment in the case of the PP, as well as the role of the concealment category as an intermediate state in vote transfers to and from Vox. Finally, the research highlights the importance of monitoring the electoral dynamics reflected in the vote recall variable and recommends assessing its potential use as a weighting variable.

Left-Wing Governments and Far-Right Success

In recent decades, support for the far right has surged in many countries. One common explanation for this is that far-right support is a backlash against left-wing governments and their policies. We investigate the causal effect of the partisan make-up of governments on the electoral results of far-right parties. Evidence from over-time comparative data and a quasi-experimental analysis based on a regression discontinuity design in Spain indicates that far-right parties benefit electorally when the current government is on the left. In further analyses, we employ a novel regression discontinuity design (RDD)-based sampling strategy to examine original individual-level survey data from Spanish municipalities close to the discontinuity cutoff. These data show that the likely mechanism underlying the backlash effect is an ideological shift to the right among the electorate when left-wing parties govern. Overall, the far right benefits more when the mainstream left governs than when the mainstream right does.

It’s Not Polarization; It’s the Radicalization of the Political Right

Polarization has become the master concept for diagnosing contemporary democratic crises. The notion denotes three features: symmetry between parties, politics as an opinion space where positions diverge, and mutual repulsion between opposing camps. Yet none of these capture current realities. Across democracies, the central dynamic is not two poles drifting apart but the transformation of the political right into authoritarianism, norm breaking, and openness to political violence. Social democratic and center-right parties tend to respond in the opposite way from what “polarization” implies: by accommodating rightward. Attempts to salvage the polarization frame with modifiers (“asymmetric,” “affective,” “sectarian,” “pernicious”) concede these realities but risk hollowing out the concept’s definitional core. These limitations reveal a deeper misdiagnosis: when one party turns antidemocratic and illiberal, incivility and conflict are inevitable—but they are symptoms, not the root problem. Misdiagnosing them as the central issue leads to viewing civility and compromise as remedies, thereby risking the legitimation of authoritarian actors. This article proposes an alternative lens: the radicalization of the political right. Developed in the study of extremism, the radicalization framework better captures asymmetric change, identity-driven politics, and the mainstreaming of illiberalism. It foregrounds identity fusion, threat narratives, elite entrepreneurship, and escalation. Concepts are never politically innocent and persisting with “polarization” risks both misdiagnosing and normalizing authoritarian threats.

Mainstreaming the populist radical right? Online news exposure and voting behavior in the 2019 European Parliament election

How does media exposure relate to support for radical right populist parties (RRPPs)? We contribute to this classic debate by analyzing the web browsing histories and survey responses of six thousand study participants in France, Germany, Italy, Spain, and the UK during the 2019 European Parliament election. Linking direct measures of online news exposure to voting behavior allows us to assess the effects of the salience of issues politicized by RRPPs on their electoral support. The likelihood to vote for RRPPs was higher when the EU was more salient in individual media diets, while exposure to the less salient issue of immigration did not increase the propensity to vote for RRPPs. Alongside consistent results for other party families and interactions with pre-existing voting intentions, the findings indicate that the electoral effects of online media are contingent on the overall salience of a specific issue and voters’ predispositions.

Undermining a Rival Party’s Issue Competence through Negative Campaigning: Experimental Evidence from the USA, Denmark, and Australia

Much party communication encourages voters to lower issue-related evaluations of rival parties. Yet, studies of such influence are rare. Drawing on research on political parties’ negative campaigning, this article starts to fill this gap. We triangulate evidence from four survey experiments across six issues in Denmark, the US, and Australia, and show that a party’s negative campaigning decreases voters’ evaluations of the target party’s issue-handling competence (i.e. issue ownership), but does not backlash on voters’ evaluations of the sponsor. Such attack on the target party does not have to be tied to a negative policy development like the crime rate to undermine the target party’s competence evaluations. At the same time, a negative policy development only undermines a party’s evaluations when it is accompanied by a rival party’s negative campaigning attack. The implications for party competition and the mass-elite linkage are important.

The Geometry of Alliances: Vote Transfer Modelling in French Two-Round Elections

Two-round legislative elections are decided not only by first-round vote shares, but by how voters whose preferred party did not advance redistribute their votes among the surviving candidates. We develop a principled model of this transfer process, grounded in multi-dimensional ideological embeddings derived from the Chapel Hill Expert Survey, and apply it to French legislative elections. Calibrated on the 2017 and 2022 elections, the model is evaluated on the unusually complex 2024 contest, in which three ideologically distinct blocs reached the second round simultaneously, achieving 90.34 percent constituency-level accuracy. We show that ideological proximity alone explains the large majority of vote transfers, that a simple left-right axis is insufficient to capture the relevant distances, and that the structural configuration of the 2024 electorate was far less favorable to the far right than pre-election forecasts suggested.

A bitter victory and a sweet defeat: the July 2023 Spanish general election

This article examines the outcome of the July 2023 election in Spain. Despite the right- and far-right bloc winning a higher share of the votes, the two main incumbent parties on the left (PSOE and...

Why Are American Presidential Election Campaign Polls so Variable When Votes Are so Predictable?

As most political scientists know, the outcome of the U.S. Presidential election can be predicted within a few percentage points (in the popular vote), based on information available months before the election. Thus, the general election campaign for president seems irrelevant to the outcome (except in very close elections), despite all the media coverage of campaign strategy. However, it is also well known that the pre-election opinion polls can vary wildly over the campaign, and this variation is generally attributed to events in the campaign. How can campaign events affect people's opinions on whom they plan to vote for, and yet not affect the outcome of the election? For that matter, why do voters consistently increase their support for a candidate during his nominating convention, even though the conventions are almost entirely predictable events whose effects can be rationally forecast? In this exploratory study, we consider several intuitively appealing, but ultimately wrong, resolutions to this puzzle, and discuss our current understanding of what causes opinion polls to fluctuate and yet reach a predictable outcome. Our evidence is based on graphical presentation and analysis of over 67,000 individual-level responses from forty-nine commercial polls during the 1988 campaign and many other aggregate poll results from the 1952–1992 campaigns. We show that responses to pollsters during the campaign are not generally informed or even, in a sense we describe, "rational." In contrast, voters decide which candidate to eventually support based on their enlightened preferences, as formed by the information they have learned during the campaign, as well as basic political cues such as ideology and party identification. We cannot prove this conclusion, but we do show that it is consistent with the aggregate forecasts and individual-level opinion poll responses. Based on the enlightened preferences hypothesis, we conclude that the news media have an important effect on the outcome of Presidential elections–-not due to misleading advertisements, sound bites, or spin doctors, but rather by conveying candidates' positions on important issues.

Political Bias Audits of LLMs Capture Sycophancy to the Inferred Auditor

Large language models (LLMs) are commonly evaluated for political bias based on their responses to fixed questionnaires, which typically place frontier models on the political left. A parallel literature shows that LLMs are sycophantic: they adapt their answers to the views, identities, and expectations of the user. We show that these findings are linked: standard political-bias audits partly capture sycophantic accommodation to the inferred auditor. We employ a factorial experiment across three major audit instruments--the Political Compass Test, the Pew Political Typology, and 1,540 partisan-benchmarked Pew American Trends Panel items--administered to six frontier LLMs while varying only the asker's stated identity (N = 30,990 responses). At baseline, all six models lean left. When the asker identifies as a conservative Republican, responses shift sharply: the share of items closer to Democrats falls by 28-62 percentage points, and all six models move right of center. A mirror-image progressive-Democrat cue produces little change; rightward accommodation is 8.0$\times$ larger than leftward. When asked who the default asker is, models identify an auditor, researcher, or academic; when asked what answer that asker expects, they select the Democrat-coded option 75% of the time, nearly the rate under an explicit progressive cue. These patterns are inconsistent with a purely fixed model ideology and indicate that single-prompt audits capture an interaction between model and inferred interlocutor. Political bias in LLMs is therefore not a fixed point on an ideological scale but a response profile that must be mapped across realistic interlocutors.

The Minimal Persuasive Effects of Campaign Contact in General Elections: Evidence from 49 Field Experiments

Significant theories of democratic accountability hinge on how political campaigns affect Americans’ candidate choices. We argue that the best estimate of the effects of campaign contact and advertising on Americans’ candidates choices in general elections is zero. First, a systematic meta-analysis of 40 field experiments estimates an average effect of zero in general elections. Second, we present nine original field experiments that increase the statistical evidence in the literature about the persuasive effects of personal contact tenfold. These experiments’ average effect is also zero. In both existing and our original experiments, persuasive effects only appear to emerge in two rare circumstances. First, when candidates take unusually unpopular positions and campaigns invest unusually heavily in identifying persuadable voters. Second, when campaigns contact voters long before election day and measure effects immediately—although this early persuasion decays. These findings contribute to ongoing debates about how political elites influence citizens’ judgments.

Legitimize or Delegitimize? Mainstream Party Strategy toward (Former) Pariah Parties and How Voters Respond

Mainstream parties have often shifted from initially portraying new competitors as undemocratic pariahs (i.e., a delegitimizing strategy) to portraying the same parties later as democratic (i.e., a legitimizing strategy). I argue that voters follow mainstream parties’ legitimizing strategies in their legitimacy evaluations of these parties. I investigate this argument with two independent survey experiments and a quantitative media content analysis in two countries that differ sharply in the nature of party competition—from mainstream parties delegitimizing a far-right party (i.e., Germany) to mainstream parties legitimizing it (i.e., Sweden). I find strong evidence that (a) mainstream parties can effectively legitimize pariah parties in the eyes of voters, (b) turning back to delegitimization has little effect, (c) legitimization is no less effective in the face of a third party’s delegitimizing strategy, and (d) legitimization resonates beyond co-partisans. The results suggest that mainstream party legitimization of pariah parties has far-reaching consequences.

When Do Parties Lie? Misinformation and Radical-Right Populism Across 26 Countries

The spread of misinformation has emerged as a global concern. Academic attention has recently shifted to emphasize the role of political elites as drivers of misinformation. Yet, little is known of the relationship between party politics and the spread of misinformation—in part due to a dearth of cross-national empirical data needed for comparative study. This article examines which parties are more likely to spread misinformation, by drawing on a comprehensive database of 32M tweets from parliamentarians in 26 countries, spanning 6 years and several election periods. The dataset is combined with external databases such as Parlgov and V-Dem, linking the spread of misinformation to detailed information about political parties and cabinets, thus enabling a comparative politics approach to misinformation. Using multilevel analysis with random country intercepts, we find that radical-right populism is the strongest determinant for the propensity to spread misinformation. Populism, left-wing populism, and right-wing politics are not linked to the spread of misinformation. These results suggest that political misinformation should be understood as part and parcel of the current wave of radical right populism, and its opposition to liberal democratic institution.

The small effects of political advertising are small regardless of context, message, sender, or receiver: Evidence from 59 real-time randomized experiments

Campaign persuasion operates with notable consistency across political parties, message tone, and information environment., Evidence across social science indicates that average effects of persuasive messages are small. One commonly offered explanation for these small effects is heterogeneity: Persuasion may only work well in specific circumstances. To evaluate heterogeneity, we repeated an experiment weekly in real time using 2016 U.S. presidential election campaign advertisements. We tested 49 political advertisements in 59 unique experiments on 34,000 people. We investigate heterogeneous effects by sender (candidates or groups), receiver (subject partisanship), content (attack or promotional), and context (battleground versus non-battleground, primary versus general election, and early versus late). We find small average effects on candidate favorability and vote. These small effects, however, do not mask substantial heterogeneity even where theory from political science suggests that we should find it. During the primary and general election, in battleground states, for Democrats, Republicans, and Independents, effects are similarly small. Heterogeneity with large offsetting effects is not the source of small average effects.
