Using two structural reforms in Finland as a natural quasi-experiment, we show that voters' policy preferences shift in response to welfare reform measures initiated by their preferred parties. In December 2020, the Finnish center-left government enacted two reforms: one reducing social protection by removing entitlements for laid-off older workers to receive income-based unemployment benefits, and the other increasing social spending by extending the compulsory education age from 16 to 18. Using a two-wave panel survey conducted before and after the government actions, the results indicate that government voters became considerably more supportive of both reforms, despite their initial low support for welfare retrenchment and its contradiction with the established ideological profile of their parties. Moreover, the shift in voters' policy preferences was substantively greater compared to their opposition counterparts and not affected by ideology and economic self-interest. Hence, voters' policy preferences show dynamic adaptability to match the party line, thereby reducing grounds for holding the parties accountable.</p>","PeriodicalId":51359,"journal":{"name":"Public Opinion Quarterly","volume":"89 2","pages":"424-444"},"PeriodicalIF":2.7,"publicationDate":"2025-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12369940/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144977961","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We call this gap between voters' <i>own preferences</i> and <i>expectations</i> regarding <i>others'</i> preferences the preference-expectation gap. Since this gap is a key mechanism of strategic discrimination, we test our argument using an experimental design modelled after research on strategic discrimination in the 2020 US Democratic primary elections.

The reasoning underlying these worries is that such communication violates widely shared communicative norms, and that exposure to it may lead to adverse consequences in the wider public. However, widespread support for respect-based norms among citizens is generally presupposed, and little is known about the extent to which norm support matters in how people react when witnessing disrespectful politicians. Using Belgian survey data (N = 2,030), we investigate whether citizens differ in the degree to which they support different respect-based norms for mediated elite communication, and whether differing levels of norm support moderate the relationship between perceived norm violations and several political outcomes (affect toward politicians; political trust; talking about politics; political information seeking). The results reveal substantial variation in norm support across the population, with differences based on sociodemographic characteristics (e.g., education level) and political attitudes (cynical, populist, polarized attitudes). This variation, moreover, matters. While depending on the outcome and norms we study, several findings show that citizens supporting respect-based norms react more negatively when perceiving norm violations more frequently, as compared to citizens caring less about these norms. Yet, whether and in what way this moderating effect occurs can differ for different types of disrespect. As such, besides showing that respectful communication is not equally important to everyone and that not everyone reacts to norm breaking in the same way, this study also underlines that not all shades of disrespect should be tarred with the same brush.</p>","PeriodicalId":51359,"journal":{"name":"Public Opinion Quarterly","volume":"89 1","pages":"155-185"},"PeriodicalIF":2.7,"publicationDate":"2025-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12166978/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144303562","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although it has been typically understood as the difference in levels of affect toward in- and out-parties, more recent research has established the relevance of polarized feelings toward party leaders as objects of affective polarization also in parliamentary systems. While several studies have cross-sectionally examined the effect of affective polarization on turnout, recent research has taken an innovative approach by systematically comparing the impact of polarized feelings toward parties and candidates in the probability of turning out in US presidential elections, showing the primacy of the latter in predicting patterns of electoral participation. We expand the contribution of those studies by providing the first longitudinal account of the relationship between affective polarization and turnout in multi-party systems, as well as the first systematic comparison of the effects of party and leader affective polarization on turnout beyond the United States. Using post-electoral survey data covering 87 elections from 13 Western parliamentary democracies collected between 1980 and 2019, our results confirm that polarized feelings toward both parties and leaders are positively associated with turnout in parliamentary democracies. More importantly, our findings highlight the growing relevance of leader affective polarization in accounting for patterns of electoral participation.

In this note, we aim to reconcile these contradictory findings by analyzing surveys spanning from 2006 to 2021 on the public's tolerance of executive concentration of power. We also collect original data under both the Trump and Biden administrations gauging support for a broad array of liberal democratic norm erosions. Support for such erosions, in fact, has been relatively similar across Democrats and Republicans once we account for the party of the president. Support for executive aggrandizement has been prevalent among supporters of the president's party at least since the second term of the Bush administration. Increased checks and balances on the executive, through divided government, amplifies this effect further.
