Ticket-splitting and strategic voting under mixed electoral rules: Evidence from Germany

Abstract.  There is more to strategic voting than simply avoiding wasting one's vote if one is liberated from the corset of studying voting behavior in plurality systems. Mixed electoral systems provide different voters with diverse incentives to cast a strategic vote. They not only determine the degree of strategic voting, but also the kind of strategies voters employ. Strategic voters employ either a wasted-vote or a coalition insurance strategy , but do not automatically cast their vote for large parties as the current literature suggest. This has important implications for the consolidation of party systems. Moreover, even when facing the same institutional incentives, voters vary in their proclivity to vote strategically.     

Voter sincerity and the time-of-voting-decision

This article explores the relationship between vote sincerity and the time at which vote decisions are finalized. It posits that a specific set of competitive circumstances are necessary for insincere voting to occur, and that voters' understanding of these circumstances can be influenced by exposure to information during a campaign. The article introduces a new method of operationalizing a commonly overlooked type of insincere voting: the protest voter. As defined here, protest voters express their political dissatisfaction by supporting an uncompetitive non-traditional party that is not their first preference. Canadian Election Study data reveal that protest voters make up a small, but noteworthy segment of the electorate and that insincere voters tend to make their vote decisions relatively late.     

Sincere and strategic voters: An Israeli study

The theoretical literature on voting behavior has shown that a rational voter may sometimes decide to vote for a candidate or party that does not constitute his or her first preference. Such voters are traditionally called strategic voters, in contrast to voters who act sincerely, i.e., those who always vote for their first preference regardless of how others are likely to vote. After discussing some of the problems associated with the definition of these two types of voters and suggesting a new operational definition, some attitudes and characteristics of these two types of voters are investigated. It was found that strategic voters constitute a very small percentage of the entire electorate, that their education level is significantly higher than that of sincere voters, that they tend more often to believe that polls influence voters' decisions and hence tend to delay their own final voting decision, that they tend more often than sincere voters to support small parties but do not tend more often than sincere voters to switch the party they decide to support from one election to the next, and that there is no significant difference between them and sincere voters regarding which governing coalition should/will form following an election.     

Why Is there So Little Strategic Voting in Canadian Plurality Rule Elections?

Using the 1988 Canadian Election Study I examine why there was only restricted strategic voting in single-member district plurality elections. In that election 19 percent of Canadian voters preferred the party that actually finished third in their constituency, but among these third party supporters only one in eight decided to vote strategically for one of the top two contenders. Strategic voting was relatively rare for two key reasons. First, many third party supporters had a strong preference for their party over all others and were therefore reluctant to rally to either of the top two contenders. Second, many overestimated their party's chance of winning and as a consequence did not feel that their vote would be wasted.     

Setting the record straight: A note on sophisticated voting under Borda's method

The purpose of this note is to correct some inaccuracies in the literature regarding sophisticated voting under Borda's method. It is shown that if a single candidate must be elected and voters vote sophisticatedly under Borda's method, then: (1) Contrary to both Black's (1976) and Ludwin's (1978) claims, a voter's undominated voting strategy may require him not to give top ranking to his most preferred candidate; (2) Contrary to Black's (1976) claim, an undominated strategy may be such that all candidates except the most preferred one are ranked last; (3) Whereas a candidate who constitutes the true bottom preference of an absolute majority of the voters will never be elected if voters vote sincerely, this candidate may be elected if voters vote strategically; (4) The election of a candidate who constitutes the true top preference of an absolute majority of the voters is not systematic: ceteris paribus this candidate may be definitely elected when voters vote sincerely but not when they vote strategically, as well as vice versa.     

Strategic coalition voting: Evidence from New Zealand

Whereas the classic literature on strategic voting has focused on the dilemma faced by voters who prefer a candidate for whom they expect has little chance of winning a seat, we consider the dilemma faced by voters in PR systems who do not expect their preferred party to be in government. We develop hypotheses relating to strategic voting over multi-party governments that we test using the New Zealand Election Study (NZES) campaign study of 2002. We find evidence that expectations play a role in structuring vote choice. While there is clear evidence of wishful thinking there is also evidence that voters respond to expectations about government formation. These expectations may mobilize voters and lead them to defect from their first preference.     

Voting for government coalitions in Ireland under single transferable vote

This paper addresses the issue of whether voters indicate a preference for a government rather than, or in addition to a preference for a party, when they cast a ballot under the system of the single transferable vote (STV). It thus contributes to the existing literature on strategic coalition voting by examining whether coalition preferences matter where electors are given the option to rank the parties in order of preference. The question then becomes: does this ranking reflect or signal a coalition preference? Using survey data from two Irish elections, this paper finds that whereas first preferences are closely aligned with coalition choices, Irish voters do not systematically use second preferences to express a view on their preferred coalition formation.     

On the mismeasurement of sincere and strategic voting in mixed-member electoral systems

Under mixed systems, voters cast two votes to elect the same legislative body: one vote for parties using proportional rules and one for candidates using majoritarian rules. Voters are said to cast straight-tickets if the candidate they vote for is of the same party as their proportional vote; otherwise, they are said to cast split-tickets. Split-ticket voting is commonly used as a measure of strategic voting as splitters are usually assumed to express their true preference in one vote but vote strategically in the other. This study challenges this practice showing that split-ticket voting does not necessarily indicate strategic voting, just as straight-ticket voting does not necessarily indicate a sincere vote. This result has wider consequences as it indicates that measuring strategic voting from observed behaviour can result in incorrect conclusions about vote choice.     

Expressive and Strategic Behavior in Legislative Elections in Argentina

In this paper I study strategic voting behavior in the Argentine Senate election for the City of Buenos Aires in 2013. I estimate and analyze the voter transition matrix between the primary and general elections using a Bayesian hierarchical model for ecological inference, utilizing a rich data set of ballot box data. The results show that strategic behavior is not widespread among the electorate in Buenos Aires. In particular, at least 75 % of voters who had the opportunity to avoid vote wasting by behaving strategically did not. I also find high levels of vote wasting when analyzing other provinces during the same election cycle. These results suggest that these electorates might be composed of a mixture of voters with strategic and expressive motivations, where the expressive factions dominate.     

Looking for Locals: Voter Information Demands and Personal Vote-Earning Attributes of Legislators under Proportional Representation

Proportional representation systems affect the extent to which elected legislators exhibit various attributes that allow them to earn a personal vote. The sources of variation in personal vote-earning attributes (PVEA) lie in informational shortcuts voters use under different electoral rules. List type (closed or open) and district magnitude (the number of legislators elected from a district) affect the types of shortcuts voters employ. When lists are closed, legislators' PVEA are of decreasing usefulness to voters as magnitude (and hence the number of candidates on a list) increases. When lists are open, legislators' PVEA are increasingly useful to voters as magnitude increases, because the number of candidates from which voters must choose whom to give a preference vote increases. As predicted by the theory, the probability that a legislator will exhibit PVEA—operationalized as local birthplace or lower-level electoral experience—declines with magnitude when lists are closed, but rises with magnitude when lists are open .     

Collective decision-making of voters with heterogeneous levels of rationality

This paper studies the collective decision-making processes of voters who have heterogeneous levels of rationality. Specifically, we consider a voting body consisting of both rational and sincere voters. Rational voters vote strategically, correctly using both their private information and the information implicit in other voters’ actions to make decisions; sincere voters vote according to their private information alone. We first characterize the conditions under which the presence of sincere voters increases, reduces, or does not alter the probabilities of making correct collective decisions. We also discuss how the probabilities change when the incidence of sincere voters in the population varies. We then characterize the necessary and sufficient condition under which informational efficiency can be achieved when sincere voters coexist with rational voters. We find that when sincere voters are present, supermajority rules with high consensus levels are not as desirable as they are in rational voting models, as informational efficiency fails under such voting rules.

     

Personal vote‐seeking in flexible list systems: How electoral incentives shape Belgian MPs' bill initiation behaviour

It is well known that different types of electoral systems create different incentives to cultivate a personal vote and that there may be variation in intra‐party competition within an electoral system. This article demonstrates that flexible list systems – where voters can choose to cast a vote for the list as ordered by the party or express preference votes for candidates – create another type of variation in personal vote‐seeking incentives within the system. This variation arises because the flexibility of party‐in‐a‐district lists results from voters' actual inclination to use preference votes and the formal weight of preference votes in changing the original list order. Hypotheses are tested which are linked to this logic for the case of Belgium, where party‐in‐a‐district constituencies vary in their use of preference votes and the electoral reform of 2001 adds interesting institutional variation in the formal impact of preference votes on intra‐party seat allocation. Since formal rules grant Belgian MPs considerable leeway in terms of bill initiation, personal vote‐seeking strategies are inferred by examining the use of legislative activity as signalling tool in the period between 1999 and 2007. The results establish that personal vote‐seeking incentives vary with the extent to which voters use preference votes and that this variable interacts with the weight of preference votes as defined by institutional rules. In addition, the article confirms the effect of intra‐party competition on personal vote‐seeking incentives and illustrates that such incentives can underlie the initiation of private members bills in a European parliamentary system.     

Proportional Representation,Majoritarian Legislatures,and Coalitional Voting

Voters in elections under plurality rule face relatively straightforward incentives. In proportional representation systems, voters face more complex incentives as electoral outcomes don’t translate as directly into policy outcomes as in plurality rule elections. A common approach is to assume electoral outcomes translate into policy as a vote‐weighted average of all party platforms. However, most of the world’s legislatures are majoritarian institutions, and elections in PR systems are generally followed by a process of coalition formation. Results obtained using this assumption are not robust to the introduction of even minimal forms of majoritarianism. Incentives to engage in strategic voting depend on considerations about the coalitions that may form after the election, and the voters’ equilibrium strategies are shaped by policy balancing and the postelectoral coalition bargaining situation, including considerations about who will be appointed the formateur.     

Insurance strategic considerations in coalition-oriented systems: A consideration set model approach

During a vote-decision process, citizens elect between some of the parties – not all of them. In this paper, we explore a potential strategic reason to include an additional alternative in the consideration set. Drawing on research from the field of strategic voting, we study incentives to defect to a party at risk of falling below an electoral threshold in order to elect a winning coalition (”insurance”). Our argument is that these types of strategic considerations occur already in the campaign, but do not always translate into choice. Using the so-called consideration set model approach (CSM), which focuses on how voters select fewer alternatives among a larger number of parties, we model vote choice over an election campaign using panel data from the Swedish National Election Studies of 2014. In line with our argument, we demonstrate that the insurance strategy was prevalent earlier in the decision-making process, when forming the consideration set.     

Momentum in the polls raises electoral expectations

Voters rely on opinion polls to help them predict who is going to win elections. But they are regularly exposed to different polling results over time. How do changes in the polls affect their expectations? I show that when the polls indicate that a party’s support has increased, voters’ expectations for that party’s performance will be higher than they would be at the same vote share but without such evidence of growth, because the party appears to have momentum. Across six survey experiments in Britain (total N > 14,000), I find that this effect persists even when changes in vote share are well within the margin of error, when comparing a small change in vote share to consistently polling at the larger vote share, when the change makes little difference to a party’s objective probability of victory, and when voters have strong preferences that might colour their interpretation of the polls. In short, the appearance of momentum in the polls robustly raises voters’ expectations that a party will win an election. This finding has major implications for any area of research in political science where expectations feature, for theoretical understandings of how people perceive the future, and for salient policy debates about the regulation of opinion polls.     

The role of the political context in voting indecision

A substantive portion of the electorate declares in pre-electoral surveys that they are undecided. However, little has been done in trying to understand who these voters are and how they finally decide their vote. In this article, we try to advance the literature by disentangling the circumstances under which voters are more likely to be undecided. While the traditional approach to the study of electoral indecision has been to characterize which individual traits make voters more likely to be undecided, this article provides consistent evidence showing that key elements of the political context may also affect electoral indecision. Using long-term harmonized data from Spanish pre-electoral surveys over 30 years, we find that voting indecision is influenced by two different types of contextual factors. First, there are some political contexts that reduce voters' cognitive costs when deciding their vote, i.e. the level of electoral competitiveness and the number of parties competing in the elections. Second, there are other political contexts that increase voters' social or expressive costs, i.e. the level of government popularity, since costs of expressing preference for the party in government increases when its public image is undermined.     

Approval voting,Condorcet's principle,and runoff elections

Approval voting allows each voter to vote for as many candidates as he wishes in an election but not cast more than one vote for each candidate of whom he approves. If there is a strict Condorcet candidate — a candidate who defeats all others in pairwise contests — approval voting is shown to be the only nonranked voting system that is always able to elect the strict Condorcet candidate when voters use sincere admissible strategies. Moreover, if a strict Condorcet candidate must be elected under ordinary plurality voting when voters use admissible strategies, then he must also be elected under approval voting when voters use admissible strategies, but the converse does not hold. The widely used plurality runoff method can also elect a strict Condorcet candidate when voters use admissible strategies on the first ballot, but some of these may have to be insincere to get the strict Condorcet candidate onto the runoff ballot. Furthermore, there is no case in which the strict Condorcet candidate is invariably elected under the plurality runoff method when voters use admissible first-ballot strategies. Thus, approval voting is superior to the plurality runoff method with respect to the Condorcet principle in its ability to elect the strict Condorcet candidate by sincere voting and in its ability to guarantee the election of the strict Condorcet candidate when voters use admissible strategies. In addition, approval voting is more efficient since it requires only one election and is probably less subject to strategic manipulation.     

Too much choice,too little impact: a multilevel analysis of the contextual determinants of preference voting

Abstract

Despite the rich and growing body of research addressing how turnout and party choice depend on the institutional context, far less is known about the impact of the political environment on voters’ propensity to vote for candidates – not parties. Recent single-country studies have focused almost exclusively on individual-level resource- and identity-based differences in preference voting. Combining data from the Comparative Study of Electoral Systems (CSES) and Participation and Representation in Modern Democracies (PARTIREP) election studies in six countries, this article provides the first comprehensive, cross-national test of the impact of macro-contextual factors on a voter’s decision to indicate a candidate preference, instead of simply casting a party list vote. It demonstrates that both the failure of preference votes to affect the allocation of seats and choice overload dissuade voters from marking a candidate name on the ballot. These contextual factors affect informed and uninformed voters differently, moreover. The findings have important implications for electoral scholars and political practitioners when designing electoral systems.     

Civic Duty and Voter Turnout

We argue that two different sets of considerations shape the decision to vote or abstain in an election–ethical and non-ethical. First the citizen may vote out of a sense of duty. Failing that, she may vote because she has strong preferences about the outcome of the election. Abstention occurs when neither duty nor a sufficiently strong preference is present. The implication is that while duty and preference each have strong positive effects on turnout, they also have a negative interaction effect, since the impact of preference is much weaker among those with a sense of duty. We present a wide array of empirical evidence that systematically supports our claim that the turnout decision is importantly shaped by this causal heterogeneity. Thus a turnout model misses something fundamental if it does not take into account the effect of civic duty.

     

Do parties perceive their voter potentials correctly? Reconsidering the spatial logic of electoral competition

Political parties strive for maximizing their vote shares. One way to achieve this goal is to attract voters from competitors. A precondition for strategies aiming at attracting these voters is that parties perceive their voter potentials among their rivals' electorates correctly. Yet, hardly anything is known about such perceptions. To fill this gap, we develop analogue measures of a party's perceived and its actual voter potential for each competitor in a party system. Combining elite and mass surveys conducted in Germany, we show that perceived and actual voter potentials depend on spatial considerations but also that not all parties are able to correctly evaluate their potentials. These deviations can be traced back to differences in the perceived placement of political actors between elites and citizens. This supports the spatial logic of party competition but it also points to potential pitfalls for strategic behavior of political parties.
