Opinion change and voting behaviour in referendums

Abstract. Voters in a referendum obtain information and derive voting cues from a variety of sources. Some of these, such as political parties or ideological orientations, are similar to those also found to be influential in elections. Others can be quite different. In some referendums, the issue may be entirely new and unfamiliar to many voters, initiating a 'learning' or 'cue–taking' process specific to the campaign itself. In referendum campaigns, parties may be internally divided and sometimes send conflicting signals to their electorates. As a result, voting behaviour in referendums often exhibits greater volatility than is found in elections. In the ten papers included in this Special Issue of EJPR , we focus on the process of opinion formation and change which occurred in a number of European, North American and Australia/New Zealand referendums held under a variety of different institutional and political conditions. In this essay, I argue that there are three distinctive patterns of opinion formation and reversal that tend to occur in referendum campaigns, each of which has significant consequences both for voting choice and for referendum outcomes.     

Cleavages, parties and referendums: Relationships between representative and direct democracy in the Republic of Ireland

Abstract. In the Irish case, a combination of quite restrictive constitutional provisions for consulting the people and extensive social and political change has produced a variety of forms of initiation of referendums and a surprisingly large number of them (25 since the late 1960s). Referendums in Ireland have frequently been related to underlying political cleavages while only very infrequently evoking major inter–party conflict. This suggests that referendums may have insulated the party system against the impact of potentially contentious issues. However, analysis of voting behaviour in the 1992 general election and abortion referendums indicates some linkage between referendum voting and party choice at the aggregate level. Additionally, evidence from the Nice Treaty referendum of 1901 suggests that the lack of major party involvement in the campaign contributed to a demonstrable gap in people's understanding of the issues. The low level of understanding in turn certainly contributed to the massive level of abstention and to a NO vote that was contrary to the preferences of almost all the parties. Thus, there are limits to the extent to which the organs of representative democracy can, or can afford to, distance themselves from the process of direct democracy.     

Voting in the 1997 Scottish and Welsh devolution referendums: Information, interests and opinions

Abstract. The rarity of referendums in the United Kingdom makes them unusual events for voters, parties and students of voting behaviour. The 1997 devolution referendums in Scotland and Wales were highly significant since they led to major constitutional changes. In the novel circumstances of a referendum, political parties and the media played an important role in providing voters with information to guide their voting decisions. Longstanding identities and opinions relating to the pros and cons of the issue involved and attitudes towards the government influenced voting. Reassuringly, opinions about the effects of devolution were highly influential.     

Class,Party and Ideology: A Danish Case Study of Electoral Behaviour in Referendums*

In this paper elements of a theory of electoral behaviour in referendums are presented and tested on a theoretically important case. Among the main determining factors — social class, political party and ideological attitude — it is shown that on a relatively simple issue with low importance for the everyday life of the voters, ideological attitude is far more important than politicál party and social class in explaining referendum voting. On this basis a scheme of analysis and a number of hypotheses are suggested for further study.     

Voting on Europe,again and again: Stability and change in the Irish experience with EU referendums

This article is about comparative voting behaviour in referendums on the EU and explores variation within one country rather than variations across countries. This enables us to control for broad national context while allowing variations in the immediate referendum context, in terms of campaign intensity and incumbency. It analyses voting behaviour in the many referendums that have taken place in Ireland. The major part of the analysis deals with the five referendums since 2001, as this allows the use of the same measurement of EU support and the use of post referendum surveys. Most attention is paid to attitude to the EU, party support and satisfaction with the incumbent government, reflecting the main debates in the literature on the issues and party cues. The relative importance of each is said to depend on contextual factors such as campaign intensity and economic strength. We find both party cues and issues matter consistently, and suggestive evidence that incumbency matters to the effectiveness of cues given by the two main pro-EU parties but the major finding is that variations in the factors driving voting behaviour in different Irish polls on Europe are slight and barely significant.     

Taking Cues on Europe? Voter competence and party endorsements in referendums on European integration

Abstract.  One of the criticisms often levelled against direct democracy is that citizens lack sufficient knowledge to vote directly on policy issues. The 'No' votes in the French and Dutch referendums on the Constitutional Treaty have highlighted the importance of examining voter competence in referendums. This article proposes a theoretical framework for evaluating competence in EU referendums. It suggests that competent voting in EU referendums is based on issue-specific preferences and requires political information. Since most voters have little detailed knowledge of European integration, they rely on heuristics and cues when deciding how to vote. The important question is how much and which type of information voters require to make competent choices. This article examines whether and under what conditions the use of party endorsements as information cues can enhance competent voting in EU referendums. These theoretical questions are examined in an analysis of the 1994 Norwegian referendum on EU membership.     

Direct democracy and regional integration: Citizens' perceptions of treaty implications and the Irish reversal on Lisbon

Analyses of voting in European Union referendums typically distinguish between ‘second‐order’ effects and the impact of substantive ‘issues’. In order to explain change in referendum outcome, two types of substantive issues are distinguished in this article. Focusing on Irish voting in the Lisbon Treaty referendums and using data from post‐referendum surveys, it is found that perceptions of treaty implications outperform underlying attitudes to EU integration in predicting vote choice at both referendums, and perceptions of treaty implications are strong predictors of vote change between the referendums. The findings have broadly positive implications for normative assessments of the usefulness of direct democracy as a tool for legitimising regional integration advance.     

Leader heuristics,political knowledge and voting in Britain's AV referendum

This paper uses data gathered in the British Election Study's 2011 AV Referendum Survey to investigate the impact of party leader images on referendum voting. The emphasis on leader images accords well with research showing that leader heuristics have sizable effects on voting in major referendums and general elections in Britain and other mature democracies. Reacting to these findings, some analysts have argued that the effects of leader images are heterogeneous, being stronger for voters with lower levels of political knowledge. In contrast, consistent with recent research in experimental economics and political psychology, it can be hypothesized that more knowledgeable voters rely more heavily on leader heuristics than do less knowledgeable individuals. Using multivariate statistical techniques developed for interpreting interaction effects in nonlinear models, analyses indicate that a political knowledge index focusing on the electoral system does not have statistically significant effects on referendum voting. However, voters' knowledge of leaders' positions on AV does interact with leader images. The analyses show that voters with higher levels of political knowledge are influenced more strongly by leader heuristics than are those who are less knowledgeable.     

On the problems of responsibility and accountability in referendums

Abstract.  Supporters of representative democracy tend to be critical of referendums. They argue that referendums give citizens more responsibility for political decisions than they have either the capacity or the competence to take. Moreover, they argue that referendums may undermine representatives' accountability. In this article, these arguments about responsibility and accountability are analyzed in the light of normative theories of democracy, especially the theory of deliberative democracy. Furthermore, different institutional forms of referendum are analyzed. Particular attention is paid to the following aspects: the extent to which governments control the use of referendums, how referendums interact with parliamentary decision making, and whether referendums are advisory or binding. It is argued that sometimes governments indeed use their control over referendums to avoid taking stands on difficult issues. More importantly, however, current forms of government-initiated referendums tend to weaken the accountability of the representatives, at least when interpreted in terms of liberal and deliberative democracy, and to distort parliamentary deliberations. Since delegation is a necessity in modern democracies, referendums should not undermine the mechanisms of representative democracy. In addition to the issues of citizens' capacity and competence, this viewpoint should be taken into account when designing referendum institutions.     

The Rise of ‘Politically Obligatory' Referendums: The 2005 French Referendum in Comparative Perspective

This article compares the use of the referendum in France by the President of the Republic with its use at the initiative of governments in other democracies. It strengthens the current view of a specificity of French referendums, consisting in their power-reinforcing use by the president, and relates it to the personal initiative and the French institutional culture. But French referendums have had other functions as well, like ensuring the adoption of legislation or increasing its legitimacy. Moreover, the use of the referendum for a variety of political ends is a dominant feature of government-initiated referendums in all countries. A straightforward relation between the type of initiative and the type of use of the referendum cannot however be drawn, just as between the initiative, or the use, and the democratic quality of the referendum. The final section focuses on the ‘politically obligatory’ referendum: from being a political resource in the hands of governments, government-initiated referendums are increasingly forced upon them. Two different reasons – appropriateness and pressures – have been found to be conducive to such a political obligation. The decision by the French president to hold a referendum on the EC Constitutional Treaty, which is closely analysed, provides a clear example of a politically obligatory referendum, in contrast to the traditional entrepreneurial use of the referendum by the president. Some decisions by other governments to submit the treaty to the people can also be interpreted in this way.     

Lessons from International Multi-Option Referendum Experiences

Referendums are regularly criticised for reducing complex policy decisions to two maximally opposed options. This reduces opportunities for voter expression and can polarise debates. Alternative referendum designs which present more than two ballot options can offer innovative opportunities, but also raise new challenges. We can benefit by learning from previous experiences with multi-option referendum voting. Discussions of such experiences are rare and have often focussed on a limited number of cases. This article provides an overview of over 100 multi-option referendum experiences around the world. It discusses the topics on which they were held and the ballot options that were offered. It then analyses the variety in ballot design in terms of questions posed and voting methods applied. Drawing on the experiences of multi-option referendums, the article concludes with lessons that can be learned in relation to initiating and designing these referendums.     

Agenda control in EU referendum campaigns: The power of the anti‐EU side

European Union (EU) referendums provide unique opportunities to study voters’ attitudes toward a distant level of governance. Scholars have long tried to understand whether EU referendum results reflect domestic (dis‐)satisfaction with the incumbent governments or actual attitudes toward the Union. Finding evidence supporting both domestic and European factors, the recent focus has thus turned to referendum campaigns. Recent studies emphasise the importance of the information provided to voters during these campaigns in order to analyse how domestic or European issues become salient in the minds of voters. These studies nonetheless overlook the asymmetrical political advantage in such campaigns. The broader literature on referendums and public opinion suggest that in a referendum, the ‘No’ side typically has the advantage since it can boost the public's fears by linking the proposal to unpopular issues. This article explores whether this dynamic applies to EU treaty ratification referendums. Does the anti‐EU treaty campaign have more advantage than the pro‐EU treaty campaign in these referendums? Campaign strategies in 11 EU treaty ratification referendums are analysed, providing a clear juxtaposition between pro‐treaty (‘Yes’) and anti‐treaty (‘No’) campaigns. Based on 140 interviews with campaigners in 11 referendums, a series of indicators on political setting and campaign characteristics, as well as an in‐depth case study of the 2012 Irish Fiscal Compact referendum, it is found that the anti‐treaty side indeed holds the advantage if it engages the debate. Nonetheless, the findings also show that this advantage is not unconditional. The underlying mechanism rests on the multidimensionality of the issue. The extent to which the referendum debate includes a large variety of ‘No’ campaign arguments correlates strongly with the campaigners’ perceived advantage/disadvantage, and the referendum results. When the ‘No’ side's arguments are limited (either through a single‐issue treaty or guarantees from the EU), this provides the ‘Yes’ side with a ‘cleaner’ agenda with which to work. Importantly, the detailed data demonstrate that the availability of arguments is important for the ‘Yes’ side as well. They tend to have the most advantage when they can tap into the economic costs of an anti‐EU vote. This analysis has implications for other kinds of EU referendums such as Brexit, non‐EU referendums such as independence referendums, and the future of European integration.     

Referendums in Western Europe – A Wave of Direct Democracy?

The aim of this article is to analyze the explanations for the increased number of referendums in Western European states. Bogdanor has explained this by the unfreezing of political alignments and institutions. After classifying referendums in 18 Western European states, it will be observed that especially the number of referendums introduced by citizens has increased wherever they are constitutionally provided, that is, in Italy and in Switzerland. Referendums in these two countries contribute most of the overall increase in the number of referendums in Western Europe. Moreover, the number of referendums concerning European integration have increased, also in states that do not have the referendum as an integral part of their political system. When it comes to the unfreezing of institutions, it must be pointed out that after the 1970s there have been no constitutional reforms which would have significantly increased the use of referendums.     

Is referendum voting distinctive? Evidence from three UK cases

The study of referendum voting follows much the same format as for general election voting. Influences on vote, however, are likely to differ significantly. Referendums decide issues, while general elections determine which party or parties will form the government. Parties are often divided on referendum issues and these issues tend to be of low salience. General elections, however, are contested by long-established parties on highly salient issues. Using panel data from the British Election Study and the 2011 Alternative Vote Referendum Study, we find that voters place different weights on party identification, issue positions, government and leader evaluations when voting in general elections and referendums, but the evidence for differential campaign effects is limited.     

Depression and attitudes to change in referendums: The case of Brexit

Depression is the most common mental illness and its profound impact on cognition and decision-making has implications for political judgement. However, those implications are unclear in the case of referendums offering a choice between status quo and change. On one hand, one component of depression is the kind of life dissatisfaction associated with voting for change. Yet cognitive models also portray depression sufferers as biased towards the status quo: they are less inclined to research change, more pessimistic about its benefits and more likely to exaggerate its potential costs. In this paper, we use data from Understanding Society to examine the impact of those cross-pressures on support for Brexit. Prior to the referendum, while life dissatisfaction and generally poor health predicted support for Leaving the European Union (EU), those diagnosed with depression were disproportionately likely to support Remain. Supporting our claim that the latter was a sign of status quo bias, this difference disappeared once the result was in and leaving the EU had become the widespread expectation. The study highlights the unexplored importance of mental health for political judgements, emphasises the multidimensionality of conditions like depression and illustrates the psychological role of status quo bias in referendum voting.     

Elite Collusion and Public Defiance: Sweden's Euro Referendum in 2003

In a referendum held on Sunday, 14 September 2003, the Swedish electorate rejected membership of the third stage of the Economic and Monetary Union (EMU). After a campaign characterised as heated by Swedish standards, and the murder of Foreign Minister Anna Lindh, the referendum delivered a clear ‘No’ majority. In this article, it is argued that while the 2003 EMU referendum may not have compromised the use of referendums as an occasional complement to representative democracy, it did indicate a substantial gap between citizens and the political elite.     

Emotions and voting behavior in self-determination referendums: the case of New Caledonia in 2018

In this article we examine the impact of emotions in an independence referendum. New Caledonia – a French Pacific territory with 270,000 inhabitants – held a self-determination referendum in November 2018, in which 56% of the voters opted to remain a part of France. We conducted a post-referendum survey with 1496 respondents that included a specific battery to measure emotions as well as control variables. We find that experiencing anger with the national status of the territory increases the probability of voting for independence, while experiencing pride reduces it. These results remain after controlling for partisan, ethnic and national identification, expected effects of independence as well as sociodemographic factors. Moreover, emotions and identity interact and increase the effect of (the lack of) national identification. Beyond the effects of the traditional control variables, the results suggest that knowledge about voting behavior in independence referendums is transferable to decolonization in Pacific Islands.     

One voter and two choices: The impact of electoral context on the 2011 UK referendum

There is a debate in the literature on referendum voting as to whether these occasions are opportunities for voters to express issue preferences in the absence of partisan politics or whether they simply serve as referendums on the current government. In part, this latter, second order account is assumed to be driven by the amount and content of media coverage, and hence information about the referendum, that is available to voters. In this paper, we address the second order question and demonstrate that holding elections concurrently both reduces the amount of media attention to the second order contest—the AV referendum in Scotland, Wales and Northern Ireland where national elections were held—and moderates media priming, thereby affecting the salient cues in the decision making of voters in those contexts.     

Coping with a two-dimensional political space: Party mobilisation in referendums on European integration

European Union referendums invite national electorates to vote on transnational cooperation and regional integration, thereby creating tension between transnational ballot issues and domestic electoral mobilisation. Because of the tension, domestic political parties are forced to confront a two-dimensional political space in EU referendums. In the referendum-generated political space, unless integration issues are more salient than domestic concerns, intra-divided and inter-converged mainstream parties tend strategically to abstain from the campaigns. Yet, explicit inter-party collusion may allow the pro-integration mainstream to form a party cartel in EU referendums. Suggestive evidence is drawn from a case study of the two Irish referendums on the Nice Treaty. Based on a party-candidate survey, Irish parties are mapped onto a latent two-dimensional political space. The findings shed new light on the initial abstention of Irish mainstream parties in the first Nice campaign and their subsequent mobilisation in the second referendum.     

Culture,Institutions and Campaign Effects: Explaining the Outcome of Malta's EU Accession Referendum

This survey examines the background to and the campaign preceding Malta's EU accession referendum. The result of the referendum, which was held on 8 March 2003, and which was the first of the EU accession referendums of 2003, was a 53.65% vote in support of membership, on a turnout of close to 91%. Explaining both the relatively low support for EU accession and the high turnout on referendum day involves weighing up the relative impact of distinctive features of Malta's political culture and institutional framework against more immediate campaign effects. While the conclusion is that the high turnout in the Maltese EU accession referendum can be traced to Malta's political culture, the relatively low but positive vote in favour of membership can only be fully understood by focusing on a range of factors, including campaign-related factors, such as the credibility of the arguments presented by the ‘yes’ and ‘no’ camps and the balance of resources available. The most important factor explaining the result of the Maltese referendum are, however, the cues provided by the political parties prior to and over the course of the referendum campaign.
