Distinguishing between the effects of swing ratio and bias on outcomes in the US Electoral College, 1900–1992

We review a number of different statistical techniques for creating seats-votes curves and apply the most reliable of these to estimate seats-votes relationships in the US electoral college 1900–1992. We consider the now rejected claim, once firmly established as part of the common journalistic and even academic wisdom, that the US Electoral College has recently been strongly biased in favor of Republicans, and show that this claim was based largely on a confusion between bias (asymmetry in the electoral college gains earned by the votes received by different parties or candidates) and swing ratio (responsiveness of change in electoral college seat share to change in popular vote). Although there has been substantial bias during this century in the way the electoral college translates Democratic and Republican votes into electoral college seats, and for the earlier party of this century (from 1900 to 1940) that bias has been in favor of Republicans, to explain why many recent electoral college majorities have been so lopsided we must look not at bias but at swing ratio.We show that the swing ratio in the electoral college has generally been increasing since 1900, rising from an average value (1900–1924) around three to an average value (1976–1992) ranging from about five to about eight, depending upon which of the various statistical estimation techniques we use. Thus, for every one point vote share gain above 50 per cent, a winning presidential candidate in a two-candidate competition can now expect to pick up somewhere between a 5 percentage point and an 8 percentage point increase in electoral college seats—giving the illusion of mandate even for relatively close contests and frequently creating apparent landslides. We show that this historical rise in swing ratio in presidential elections is due almost entirely to changes in the responsiveness of outcomes in the US South as the influence of the Civil War slowly (very slowly) erodes. Drawing on the analysis of the determinants of bias and of swing ratio in the House of Representatives in Brady and Grofman (1991b), we show that the increases in electoral college swing can be accounted for by the nationalization of presidential competition as signaled by the decrease over time in the standard deviation of Democratic share of the two-party vote across states, and that changes in bias can be linked to changes in the magnitude of differences between the mean and the median of that distribution.     

Party registration and party self-identification: Exploring the role of electoral institutions in attitudes and behaviors

How do electoral institutions affect self-identified partisanship? I hypothesize that party registration acts to anchor a person's party identification, tying a person to a political party even when their underlying preferences may align them with the other party. Estimating a random effects multinomial logit model, I find individuals registered with a party are more likely to self-identify with that party and away from the other party. Party registration also affects voting in presidential elections but not in House elections, leading to greater defection in the former where voters have more information about the candidates. These insights illuminate varying rates of electoral realignment, particularly among southern states, and the makeup of primary electorates in states with and without party registration.     

Manufactured Responsiveness: The Impact of State Electoral Laws on Unified Party Control of the Presidency and House of Representatives, 1840–1940

The modern history of divided government in America suggests that the framers succeeded in creating a government unresponsive to popular passions. Yet in the nineteenth century the party winning the presidency almost always captured control of the House of Representatives. Why and how could nineteenth century national elections be so responsive that they resemble parliamentary outcomes? We identify electoral institutions present in the states that directly linked congressional elections to presidential coattails. Specifically, we estimate the impact of state ballot laws and the strategic design of congressional districts on presidential coattail voting from 1840 to 1940. We find that presidential elections, as mediated by state electoral laws, strongly account for unified party control of the House and the presidency throughout the nineteenth century.     

The rise of the opposition party in Taiwan: explaining Chen Shui-bian’s victory in the 2000 Presidential election

The 2000 Taiwan presidential election drastically changed Taiwan’s political landscape. For the first time in Taiwan, an opposition party candidate, Chen Shui-bian, won the presidential race, receiving 39.3% of the popular vote. To understand the factors that determined the election’s outcome, we analyze survey data from the 2000 presidential election. First, we study whether a divided ruling party was the cause of the opposition party candidate’s victory. That is, would the ruling party have lost if one of the trailing candidates had opted not to run? Second, there were charges following the election that the Kuomintang misled people into believing their candidate was still leading in the polls, when he was really running third, and this misinformation led people to vote differently than they would have otherwise, possibly giving the election to the opposition party candidate. We examine the validity of this claim by measuring the degree to which strategic voting could have influenced the outcome. Third, to understand the underlying dimensions of the electoral competition in Taiwan and to understand each candidate’s electoral support, we run a multivariate statistical model to study how strategic voting, candidate personalities, party identification, and issues influenced respondents’ vote choices. Finally, we discuss the effects of election polling data on election outcomes.     

Centripetal and Centrifugal Incentives under Different Electoral Systems

In a seminal article, Cox (1990) suggested that electoral systems with larger district magnitudes provide incentives for parties to advocate more extreme policy positions. In this article, we put this proposition to the test. Informed by recent advances in spatial models of party competition, we introduce a design that embeds the effect of electoral rules in the utility function of voters. We then estimate the equilibrium location of parties as the weight voters attach to the expected distribution of seats and votes changes. Our model predicts that electoral rules affect large and small parties in different ways. We find centripetal effects only for parties that are favorably biased by electoral rules. By contrast, smaller parties see their vote share decline and are pushed toward more extreme equilibrium positions. Evidence from 13 parliamentary democracies supports model predictions. Along with testing the incentives provided by electoral rules, results carry implications for the strategies of vote‐maximizing parties and for the role of small parties in multiparty competition.     

Voter preferences and party loyalty under cumulative voting: Political behaviour after electoral reform in Bremen and Hamburg

Many electoral systems constrain voters to one or two votes at election time. Reformers often see this as a failing because voters' preferences are both broader and more varied than the number of choices allowed. New electoral systems therefore often permit more preferences to be expressed. In this paper we examine what happens when cumulative voting is introduced in two German states. Even when we allow for tactical considerations, we find that the principle of unconstrained choice is not widely embraced by voters, although in practice, too, many seem to have preferences for more than just one party. This finding has implications for arguments relating to electoral reform as well as how to conceive of party affiliations in multi-party systems.     

Issue Voting as a Constrained Choice Problem

Prevalent models of issue voting view vote choice as a choice among party policies. Choice sets are implicitly assumed to be the same for all voters, and their composition is left to researchers' discretion. This article aims to relax such assumptions by presenting a model with a varying probability of inclusion in the choice set. We apply the “constrained choice conditional logistic regression” to survey data from the 1989 parliamentary election in Norway to examine the effects of party identification of voters and electoral viability and policy extremity of parties on individual voters' choice set compositions. Further, we look into the effect of parties' policy positions on their electoral fates under alternative assumptions about the composition of voters' choice sets. We find that voters' choice set composition conditions both the effects of their policy considerations on vote choice and those of parties' policy offerings on their electoral fates.     

Political Mobilisation,Political Participation and the Power of the Vote

This article proposes a framework to recast our thinking about political participation. The approach adopted insists on the role of collective actors and their agents – the political elites – in the democratic process and, by implication, in determining the amount and forms of individual political participation. The proposed framework builds on a simple model of representative government and introduces some major changes in the political context which have become ever more conspicuous in the course of the last 30 years, and which are substantially modifying the conditions for conventional (electoral) and unconventional political participation. Prominent among these changes are the increasing role of the media in politics, and the decline of party control over the voters. These changes tend to enhance both electoral and non-electoral forms of participation. Another set of contemporary institutional changes reduces the electoral accountability of political decision-makers, with expected consequences that are more ambiguous for both electoral and non-electoral participation.     

Multiparty electoral competition in the Netherlands and Germany: A model based on multinomial probit

A typical assumption of electoral models of party competition is that parties adopt policy positions so as to maximize expected vote share. Here we use Euro-barometer survey data and European elite-study data from 1979 for the Netherlands and Germany to construct a stochastic model of voter response, based on multinomial probit estimation. For each of these countries, we estimate a pure spatial electoral voting model and a joint spatial model. The latter model also includes individual voter and demographic characteristics. The pure spatial models for the two countries quite accurately described the electoral response as a stochastic function of party positions. We use these models to perform a thought experiment so as to estimate the expected vote maximizing party positions. We go on to propose a model of internal party decision-making based both on pre-election electoral estimation and post-election coalition bargaining. This model suggests why the various parties in the period in question did not adopt vote maximizing positions. We argue that maximizing expected vote will not, in general, be a rational party strategy in multiparty political systems which are based on proportional representation.     

Apartisans and the changing German electorate

The concept of party identification is central to our understanding of electoral behavior. This paper builds upon the functional logic of party identification and asks what occurs when more Germans manage the complexities of politics without needing to rely on habitual party cues—what we label as Apartisans. We track the distribution of party mobilization and cognitive mobilization within the German electorate from 1976 until 2009. Then, we demonstrate the importance of these mobilization patterns by documenting strong differences in electoral commitment, the content of political thinking, and electoral change. The results suggest a secular transformation in the characteristics of the public has led to a more differentiated and dealigned German electorate.     

Strategic Party Government: Party Influence in Congress, 1789–2000

Why does the influence of Congressional parties fluctuate over time? Building on prevailing answers, we develop a model, Strategic Party Government, which highlights the electoral motives of legislative parties and the strategic interaction between parties. We test this theory using the entire range of House and Senate party behavior from 1789 to 2000 and find that the strategic behavior of parties complements members' preferences as an explanation for variation in party influence. Specifically, the strongest predictors of one party's voting unity are the unity of the opposing party and the difference between the parties in the preceding year. Moreover, we find strong links between party behavior in Congress and electoral outcomes: an increase in partisan influence on legislative voting has adverse electoral costs, while winning contested votes has electoral benefits.     

Try Federalism

The present article follows up a previous study (Anckar 1998) which showed a strong association between size and party system fragmentation. The aim of the article is to see whether the explanatory power of size can, in fact, be attributed to a federal form of government. 77 countries with free party systems constitute the research population. The dependent variable has three components: number of parties, electoral support for the leading party, and the 'effective number of parties' calculated according to the Laakso-Taagepera formula. Preliminary tests reveal that federal states have a more fragmented party system than unitary states. However, when controlling for size, electoral system, the 'effective threshold,' and presidentialism, the results clearly show that federalism is overshadowed by size and also, to a lesser extent, by the effective threshold.     

Economic shocks and democratic consolidation: Historical evidence from party-level electoral volatility in France

The emergence of a stable party system is a central aspect of democratic consolidation. Building a novel historical dataset, we analyze how economic growth affected the party-level electoral volatility during the consolidation of the French democracy over the Third Republic (1870-1940). We document an asymmetric effect in that positive economic shocks produced electoral stability, while negative shocks had not the expected destabilizing effect. Moreover, a positive shock had a disproportionally stabilizing effect during economic prosperity, four times stronger than during an average economic conjuncture. As France experienced strong positive shocks over this period, our results imply that the party system consolidation may have been driven by a few exceptionally high growth episodes. We also find evidence suggesting that positive shocks developed voters’ support for institutionally stable parties.     

The long and the short of it: Electoral institutions and the dynamics of party system size, 1950–2005

While institutional theories of party system size are usually examined cross‐nationally, there is ample reason to expect that changes in electoral institutions will affect party system size within countries as well. Although some of this effect may occur immediately, most of the effects are likely to be realised over time and across subsequent elections. A series of error‐correction models examine the short‐ and long‐term effects of changes in electoral institutions on party system size. The results indicate that changes in electoral institutions do produce the expected effects on party system size, and that these effects occur mostly over the long term.     

Demassified Mass Parties or Overloaded Cadre Parties? The Impact of Parties on Electoral Outcome in Finland*

This article examines the frequently cited hypothesis of the changes in modern party organizations towards the catch-all model, and of the attempt of political parties to counter threats of electoral failure by intensifying membership support. The results indicate that in Finland former mass parties have been demassified and cadre parties have been overloaded. However, there are differences in party alignments and in the internal organizational structure of the parties that make a strict application of the catch-all concept problematic The findings also give evidence of a threat of declining electoral success that has implications for the membership support in the parties in very special situations. The threat from other parties seems to have only little or no effect on the membership figures. But when this threat is combined with a steady erosion in the traditional social bases of the parties, then the party response can be strong for the purpose of widening the electoral market by personal influence, as was the case with the rural Center party in Finland.     

Government Formation in the Nordic Countries: The Electoral Connection

Government formation is guided by several principles, such as majority, plurality and electoral principles. According to the electoral principle, parties that increase their share of seats in the elections should form the government, parties that lose seats joining the opposition. We analyse the fulfilment of this principle in the five Nordic countries. In Denmark, Finland and Iceland the majority of governments contained parties that both won and lost in elections, whereas in Sweden nearly half of the governments included only parties that lost seats. Only in Iceland and Denmark does election success translate to an increased probability of a government place in an increasing way. In Norway and particularly in Sweden big losers have better chances of being in government than big winners. Party system attributes are not related to the fulfilment of the electoral principle. To shift our analysis to individual parties, prime ministers come more likely from parties that are big winners. Winning does not explain the probability of becoming a coalition partner. If a party wants to be in government it is more important to avoid losing seats than to be an actual winner. Coalition partners are more likely to be mid–sized parties, a finding probably explained by the desire of the formateur party to maximise its policy influence in the government.     

The effects of campaign finance spending bans on electoral outcomes: Evidence from the states about the potential impact of Citizens United v. FEC

This paper seeks to understand the effect of campaign finance laws on electoral outcomes. Spurred by the recent Supreme Court decision, Citizens United v. Federal Election Commission (2010), which eliminated bans on corporate and union political spending, the study focuses on whether such bans generate electoral outcomes that are notably different from an electoral system that lacks such bans. We look to two key electoral dynamics that such bans might influence: the partisan balance of power and the success of incumbents. Using historical data on regulations in 49 American states between 1968 and 2009 we test alternative models for evaluating the impact of corporate spending bans put in place during this period. The results indicate that spending bans appear to have limited effects on election outcomes.     

Institutions and the stabilization of party systems in the new democracies of Central and Eastern Europe

Most explanations of party system stability focus on the strength of mass-elite linkages. We highlight the role of institutions, focusing on how electoral rules and elected institutions, especially the presidency, impact elites' incentives to coordinate on a stable set of parties or to form new parties, thus affecting electoral volatility. Using Central and Eastern European elections data, we find that directly elected presidents increase volatility and that presidential power magnifies this effect. Absent a directly elected president, high district magnitude is associated with increased volatility, but district magnitude dampens the impact of an elected president on volatility; hence, our findings underscore the interactive impact of institutions on party systems. We also find evidence that bicameralism and concurrence of presidential and parliamentary elections decrease electoral volatility. Our model not only explains persistently high electoral volatility in Eastern Europe, but the extreme stability of Western European party systems.     

Changing Ideas: Organised Capitalism and the German Left

What determines party positions on issues of economic governance? Most previous research has pointed either to the presumed material interests of the parties' clienteles, or to the political institutions that shape electoral competition. Both approaches do well in explaining cross-national variation, but neither can adequately account for changes over time. This article documents German Social Democrats' policy preferences and the underlying discourse on organised capitalism from 1880 onward to highlight the crucial role of historical context. The interests reflected in party positions cannot simply be read off the material environment. Instead, as suggested by constructivist work on preference formation, they depend on theories regarding the causal effect of alterative policy measures. Following Peter Hall, we treat the evolution of such theories as a ‘process structured in space and time’, by illustrating how ‘context factors’ affect the relative salience of the multiple considerations pertaining to organised capital.     

The retention of state governors

In this paper, we have provided some support for several hypotheses about the determinants of which governors get reelected. The benefit from being a member of a particular party varies from state to state and from year to year. Personal characteristics such as age are also important. The logits give some support to the importance of coalition formation; reelection is easier in states with low voter turnout and in farm states. The paper is most concerned with the connection between the economic performance and the electoral success of incumbent candidates for governor, and we find support for a model of electoral acountability, in which governors are powerful in state governments and state governments have the ability to differentially tax fixed factors relative to neighboring states.This paper raises some important issues regarding the measurement of variables in political economy, which have wide applicability to other studies in the economics of politics. Peltzman (1988) finds that the difference between the growth rate in state personal income and the national growth rate over a one to four year period prior to the election does not affect gubernatorial electoral outcomes. Concurrently, we find that the current year's growth rate in state personal income and its difference from the national growth rate are not significantly related to electoral success but that the average deviation from predicted state personal income during the governor's tenure in office is significantly related to the odds of getting reelected. That is, the data reject simplistic views of voter behavior and support a sophisticated model of voter behavior. Similarly, Peltzman (1988) has greater success using more sophisticated, cumulative measures of national economic performance.
