Competing loyalties in electoral reform: An analysis of the U.S. electoral college

A central tenet in the electoral systems subfield is that parties, when in power and motivated by partisan interest, seek desired outcomes via the strategic adoption of electoral rules. Such a focus, however, omits a key point: electoral rules also distribute power among geographic units. If, within a party, the partisan and geographic interests of some members conflict, then the canonical relationship between partisanship and rule choice may be conditional. The U.S. electoral college provides an opportunity to test for such intra-party variation, because it advantages some states over others and thus makes salient geographic allegiances. Using an original dataset on one reform proposal—the National Popular Vote Interstate Compact (NPVIC)—I find evidence of competing loyalties. Although NPVIC advances furthest when Democrats control state lawmaking, a state's status as a swing—but not as an overrepresented—state weakens the relationship to the point where even Democrats are unlikely to aid NPVIC.     

Symposium on “The nationalization of electoral politics: Frontiers of research”

This editorial introduces the theme of the symposium which addresses the most recent advances in the field of the nationalization of electoral politics. After a decade of an increasing number of contribution in this field, the symposium takes stock of the diversity of applications of nationalization studies, the progress in data collection, and its innovative methods in designs including it as both a dependent and independent variable and analyzing it both for legislative and presidential elections. The editorial reviews the growth and diversification of the literature over time and illustrates in what directions it has evolved mapping out an increasingly rich and complex theory. It links the articles of the symposium to this evolution of the literature and discusses their innovative character.     

Demonisation and electoral support for populist radical right parties: A temporary effect

Since the 1980s, Western Europe has experienced the surge of populist radical right parties. In an attempt to ward off these electoral newcomers, established parties have pursued strategies of disengagement, such as exclusion and de-legitimisation. This study examines the electoral effects of an excessive form of de-legitimisation, which we label ‘demonisation’. We estimate the effects of demonisation on electoral support for the Dutch Freedom Party (PVV) and its predecessor Groep Wilders. Time series analyses show that demonisation has a negative effect on electoral support, but only for Groep Wilders. Once the populist radical right party has made a successful entry into the party system, demonisation does not have its intended consequences.     

Theoretically,yes, but also empirically? How the corruption-turnout link is marginally explained by civic duty to vote

Corruption is generally associated with low electoral participation. A recurrent explanation of the negative correlation between corruption and electoral turnout involves the rational calculus of the costs and benefits of voting. More specifically, in a context of high corruption, citizens do not vote because they think that doing so will hardly affect policy decisions. A number of influential studies has argued that corruption affects citizens' electoral engagement in a different and more fundamental way as well: It erodes their sense of civic duty to vote in elections. Yet, a relation between corruption and civic duty and a mediation effect of the attitude remains empirically untested. This article examines empirically whether perceived corruption and sense of civic duty are correlated, as well as whether civic duty mediates the relation between perceived corruption and turnout. It does so with the pooled Making Electoral Democracy Work data, as these data contain measures on individuals’ sense of civic duty to vote in four election levels, namely, national, regional, European, and municipal elections, as well as on their perception of corruption in each of these government levels, and on their participation in these four election levels as well. I find a weak relation between perceived corruption and civic duty, and a low mediation effect of the attitude (compared with rational factors), irrespective of the election level.     

Quality challenger emergence under the top-two primary: Comparing one-party and two-party general election contests

Prior research finds that the emergence of a quality challenger is one of the most important factors predicting whether incumbents will be vulnerable. Reformers in California and Washington envisioned that the top-two primary reform would increase electoral competition by allowing for general election contests that feature two same-party candidates in safe districts. In this research note, I investigate the degree to which these expectations have been fulfilled by looking at the prevalence of quality challengers in U.S. House contests. I compare one-party and two-party general election contests, finding that incumbents are significantly more likely to face a quality challenger from the same party than from the opposite party, all else equal. In contrast, when both states used traditional primaries prior to reform, incumbents were no more likely to face a quality challenger in the primary election than in the general election. Findings reveal a key way in which the top-two primary may fulfill reformers’ expectations and complement our understanding of how electoral institutions condition challenger entry decisions.     

Racial attitudes & political cross-pressures in nationalized elections: The case of the Republican coalition in the Trump era

While scholars have found that Trump was able to capitalize on the racial attitudes of white voters, it is less clear how these racial attitudes influenced vote-choice across partisan and ideological cleavages in the electorate. It is also unclear whether racial attitudes affected voting at the congressional level or electoral outcomes at the aggregate level. Using a novel measure of racial attitudes at the subnational level and survey data, we make three clear findings: (1) Trump and Republican congressional candidates benefited from conservative racial attitudes both at the aggregate level and among white voters, (2) this electoral benefit for Republicans persisted during the 2018 midterm elections, and (3) the effect of attitudes on vote-choice did not significantly vary across partisan and ideological cleavages in the white electorate. Our findings suggest that, even during the era of highly nationalized and partisan elections, racial attitudes are still a mechanism by which Republicans can win significant electoral support among Democrats and relatively liberal voters in the white electorate. These findings have implications for the growing salience of race in the Republican electoral coalition.

L'impact du mode de scrutin sur l'élection des femmes à l'Assemblée fédérale Suisse (1995‐2003)

Cet article analyse l'impact du système électoral sur l'élection des femmes à l'Assemblée fédérale (1995‐2003). La littérature a souvent mis l'accent sur l'importance du système proportionnel en vue de l'amélioration de la représentation des femmes au Parlement en se concentrant souvent uniquement sur le taux de femmes élues. Dans cet article, nous argumentons qu'il est nécessaire d'étudier les trajectoires des candidats et de prendre en compte à la fois les candidats hommes et femmes. Nous montrons que l'effet women‐friendly du système proportionnel au Conseil national semble davantage jouer au niveau de la stratégie de désignation des candidats et des candidates que lors de leur élection, et ce particulièrement pour les partis politiques du centre et de droite.     

Institutional determinants of the largest seat share

The degree of predominance of the largest party in a representative assembly affects government formation and survival. The seat share of the largest party, in turn, is constrained by the interaction of assembly size and electoral district magnitude in the following way. When all S seats in an assembly are allocated in districts of magnitude M, a logical quantitative model proposes that the largest fractional share is s₁ = (MS)^−1/8. As a curve, the model is found to fit with R² = 0.509, considering data from the averages of 46 periods in 37 countries, during which the electoral rules were essentially steady. As a worldwide average, the expression s₁(MS)^1/8 = 1 holds within 1%. Deviations from this average express the impact of various country-specific political and socio-cultural factors that can be investigated once the basic institutional constraints are controlled-for. This means that the degree of largest party predominance may be engineered to hover around a desired average by adjusting assembly size, and district magnitude, while keeping country-specific factors in mind.
