Components of partisan bias originating from single-member districts in multi-party systems: An application to Mexico

We extend the estimation of the components of partisan bias—i.e., undue advantage conferred to some party in the conversion of votes into legislative seats—to single-member district systems in the presence of multiple parties. Extant methods to estimate the contributions to partisan bias from malapportionment, boundary delimitations, and turnout are limited to two-party competition. In order to assess the spatial dimension of multi-party elections, we propose an empirical procedure combining three existing approaches: a separation method (Grofman et al. 1997), a multi-party estimation method (King 1990), and Monte Carlo simulations of national elections (Linzer, 2012). We apply the proposed method to the study of recent national lower chamber elections in Mexico. Analysis uncovers systematic turnout-based bias in favor of the former hegemonic ruling party that has been offset by district geography substantively helping one or both other major parties.     

Ideological Primary Competition and Congressional Behavior

Abstract

Primary challenges on an incumbent’s more extreme flank have become increasingly common in congressional elections. We explore the consequences on the legislative behavior of successful incumbents following these types of challenges. We propose that the effect of extreme ideological primary challenges is conditioned on whether the member belongs to the majority or the minority party. We test our expectations on primary elections from 2000 to 2012 and corresponding changes in voting behavior in the next Congress. We find that incumbents in the majority party who have defeated an extreme ideological primary challenge are less likely to support their party, especially on key votes. We expect this reaction is because they fear appearing too moderate and thereby encouraging another extreme ideological primary challenge. We find that incumbents in the minority party who face an extreme ideological challenge do not change their general voting behavior, but are more likely to vote with their party on key votes.     

A GIS-based spatial analysis on neighborhood effects and voter turn-out:: a case study in College Station,Texas

This paper examines individual voter turn-out and its putative relationship with voting outcomes at the voting precinct level. Via a GIS-based address matching procedure, we were able to georeference individual voters (registered voters who casted their votes) and non-voters (those registered voters who did not cast their votes) for three recent local referenda in College Station, Texas. We then conducted a scale-sensitive, second-order spatial analysis for the spatial distribution of voter turn-outs, followed by a spatial clustering analysis of the voting results using Getis–Ord’s G_i statistic. We found that the extent of neighborhood effects in local elections is heavily influenced by the voter turn-out. If voter turn-out is clustered at intermediate and large scale, voting results tend to be clustered and also exhibit a sharp polarization between high and low values. If voter turn-out tends to be uniform/regular at intermediate scales but randomly distributed at both small and large scales, there appears to be less clustering in the voting results and thus lack of the neighborhood effect. If the voter turn-out pattern is mixed-uniform/regular at the small scale, random at the intermediate scale, but clustered at the large scale, the voting results show a stronger neighborhood effect.     

Split ticket voting in Australia: Dealignment and inconsistent votes reconsidered

This article critically examines the traditional American assumption that split ticket voting represents an indicator of partisan dysfunction and dealignment. It is argued that this assumption ignores the impact of system‐specific voting structures on voting patterns. Thus, we propose alternatively to explore ticket spitting in Australia, where a system of preferential vote and proportional representation creates very different structural opportunities for voters to pursue tactical votes that need not engender dealignment. Aggregate and survey data from the 1987 and 1990 federal elections are analysed. Aggregate results show a general upturn in voting consistent with tactical voting, while survey results suggest Australian ticket splitters are a tactically aware, politically interested subset who, in the context of wavering, but not supplanted partisanship, utilise especially Senate minor party votes to put a brake on major party hegemony.     

Italian candidates under the Rosato mixed electoral system. In search of personal votes in the plurality tier?

The Rosato law has established a new electoral system featuring single-member districts (S.M.Ds) along with a prevailing proportional tier. S.M.Ds are typically associated with individual incentives to cultivate a personal vote and with a more direct link between representatives and their local constituency. This article investigates patterns of personalized votes in the Italian elections of March 2018 by analysing voting data about candidates for the Chamber of Deputies who ran in the plurality tier. Results reveal that only a minor – although not negligible – portion of Italian voters cast their ballot for an individual candidate only, and that these votes had almost no impact on the outcomes of competition in S.M.Ds. Moreover, some interesting differences across geographical areas, parties and coalitions emerge in the use of personalized vote.     

Applying new approaches to modeling diet and status: isotopic evidence for commoner resiliency and elite variability in the Classic Maya lowlands

Classic Maya states were characterized by a high degree of socioeconomic stratification. This paper investigates the degree to which status, as defined by grave goods and tomb construction, influenced dietary patterns of elites and commoners throughout the Classic Period (200–900/1000 AD) of the southern lowlands. We compile a database (N = 102) of previously-published stable isotope ratios (δ¹³C collagen, δ¹³C apatite, and δ¹⁵N collagen) from Maya bone mineral and collagen, and interrogate these data through two new isotopic modeling techniques: a simple carbon isotope model ( Kellner and Schoeninger, 2007; Froehle et al., 2010) and a multivariate isotope model ( Froehle et al., 2012). We find that Maya elite diet varied significantly through time in terms of maize consumption and trophic level, while commoner diet remained remarkably stable. These findings provide new information relevant to studies of ancient Maya class structure and to studies of subsistence strategies of the pre-Columbian Americas.     

Voting technologies and residual ballots in the 2000 and 2004 presidential elections

The accurate counting of ballots is essential for a functional democracy. In recent elections, particularly the exceedingly narrow presidential one in 2000, widespread concerns surfaced that votes were not being counted accurately. This paper examines major voting technologies, their advantages and disadvantages, and the significance of residual ballots (overvotes and undervotes) across U.S. counties in the presidential elections of 2000 and 2004. In the 2000 election, 1.9 million ballots were voided, as were more than 2.3 million in 2004. The analysis explores three fundamental questions: (1) Do voting technologies tend to favor one political party over its rival? (2) Do voting technologies tend to favor one ethnic group over another? (3) Do voting technologies favor urban areas over rural ones? The empirical results consistently deny the existence of any of these biases at the national level, although the possibility of local bias remains an open question. The conclusion links these issues to the on-going debate about voting technology reform.     

The impacts of extra-territorial voting: Swings,interregnums and feedback effects in New Zealand elections from 1914 to 2011

How are elections affected by the votes of people living abroad? The majority of states now allow extra-territorial voting in some form, but the research literature on this topic remains underdeveloped. Moreover, even though extra-territorial voting raises issues about the relationship between territory and political obligation that are relevant to political geographers, political geography has been under-represented in discussions on the topic. Against this background, this research examines a century of overseas voting impacts in New Zealand, a country with an unusually long recorded history of such activity. The study identifies three types of extra-territorial voting impact over the period 1914-2011, referred to as swings, interregnums and feedback effects.     

Electoral salience and the costs of voting at national, sub-national and supra-national elections in the UK: a case study of Brent, UK

This paper considers the impact of distance to polling station upon electoral turnout. Using polling station level data from a London borough, it examines three types of election – parliamentary, European and local elections – over a twenty year period. The UK is notable among western liberal democracies for its relatively large turnout gap – the percentage point difference between turnout at elections for the Westminster parliament compared to that for other institutions, including local councils and the supra-national European parliament. This research considers the hypothesis that in high information, high salience elections for the national parliament the costs of voting associated with travelling to a polling station to vote in person are perceived as either low or insignificant but that in low information, low salience elections, those costs are perceived as higher and may act as a deterrent upon voting. A series of multi-level models consider the relationships between the dependent variable, percentage turnout, and a range of independent variables, including socio-economic characteristics, marginality as well as the spatial context. We show that there is indeed a relationship between distance and voter turnout, and other spatial and contextual variables, which are stronger for the lower salience European and local elections than for the higher salience national elections. Hence we conclude that the local geography of the polling station can have a significant impact on voter turnout and that there should be a more strategic approach to the siting of polling stations.     

Local voting at local elections revisited: ‘Friends and neighbors voting’ at mayoral elections in rural Poland

Voters' tendency to support local candidates, often referred to as ‘friends and neighbors voting’, is a spatial-political phenomenon studied for over 70 years. The last decade has seen a revival of interest in this issue. Relevant studies typically focus on large-scale national electoral contests, such as national parliamentary elections. The research efforts targeting local elections are, by contrast, scarce, in most cases dating back to the 1970s. In this article, we address this relative gap in the electoral geography literature and study ‘friends and neighbors voting’ at the most recent set of mayoral elections in Poland, held in 2018. Based on a rich dataset, covering elections in over 700 rural municipalities, we demonstrate strong local candidate effects in both voter choice and voter turnout. The results point to the potential relevance of both geographic distance and a place (locality) attachment; voters tend to prefer candidates living close to them and candidates enjoy an additional surplus of votes in their home localities. Our results also tend to echo the sparse previous findings emphasizing the possibility that the presence of a local candidate boosts voter turnout in a given area. While the limitations of our data do not allow unequivocal conclusions about the exact mechanisms driving the aforementioned effects, we put forward a number of plausible, grounded conjectures as to how such effects may operate.     

‘Two‐party preferred’: The analysis of voting figures under preferential voting

Since the Commonwealth Electoral Commission is issuing full distribution of the preferences of votes for minor candidates at elections for the House of Representatives, it is now possible to assess the use of these and compare them with previous estimates. This paper therefore looks at the concept of the ‘two‐party preferred vote’ in the light of such publication and the introduction of optional preferential voting in New South Wales.     

Transnationalism and expatriate political engagement: the case of the Italian and French voting in Australia

The aim of this article is to provide an appreciation and analysis of the expatriate connectivity of Italian and French citizens from their place of residence in Australia through their respective elections in their home countries. Specifically, the article examines the case of Italians in Australia voting in the 2013 Italian elections and equally that of French citizens in Australia voting in the French presidential and the following legislative elections in 2017. The article examines the voting patterns there might be between those voting in their home country (Italy and France) and those voting in external electoral colleges (in this case, the relevant Australian college). The article shows that those living abroad—in this case, Australia—provide different political choices and less surprising low voting participation compared to the domestic districts. It also highlights that the transnational community can be, and is, influenced by the political context of their host country, which will be different from that which occurs in their home country.     

Vote evolution in Spain, 1977–2007: A spatial analysis at the municipal scale

This paper presents a spatial analysis of the results in the general elections of contemporary Spain (1977–2007). By using electoral data at municipal level, we have traced back the evolution of the vote at high spatial resolution, thus providing a more accurate overview of the evolution of modern Spanish politics and offering empirical evidence on the nationalization thesis. We demonstrate that this approach reveals several processes that remain hidden when aggregated data are used, especially the clustering patterns in the smooth transition from dictatorship to full democracy (the so-called Spanish Transition). We found a statistical normalization process of the left/right dynamics with a growing number of balanced municipalities with a similar number of votes for left and right parties. The tendency towards a Gaussian histogram centered on a value of 50% for the left vote is an indication of political normalization after 40 years of dictatorship.     

A Review of “Political Foundations of Judicial Supremacy: The Presidency,the Supreme Court,and Constitutional Leadership in U.S. History”

In 1974 David Mayhew proposed that incumbency was increasingly important in deciding elections to the House of Representatives. One cause of this increase, he speculated, might be more effective use of the resources of office by incumbents bent on improving their electoral position. These suggestions heavily influenced subsequent research on congressional elections, and helped shape the design of the 1978 national election survey by Michigan's Center for Political Studies. This essay surveys that line of research, except for the recent articles making use of the 1978 data or dealing specifically with campaigning, which will be treated in a sequel. Full length books, articles before Mayhew's, and unpublished papers are excluded, except for certain works of particular relevance.     

Globalization,robotization, and electoral outcomes: Evidence from spatial regressions for Italy

Criticism of economic globalization and technological progress has gained support in Italy in the last two decades. However, due to the differentiated exposure of local labor markets to this process, electoral outcomes have varied considerably across the country. By observing the local impact of three global economic phenomena (flows of migrants, foreign competition in international trade, and diffusion of robots) alongside with the patterns of local electoral outcomes potentially associated with discontent, this study analyzes the economic forces driving the evolution of general elections in 2001, 2008, and 2013 in Italy. The analysis reveals that all these global factors had an impact on political outcomes associated with discontent, albeit in different ways and changing over time. All three factors are associated with increases in votes for far‐right parties in the period 2001–2008, but only robotization continues to have such an impact in the following period, while immigration is associated with an increase in votes for the Five‐Star Movement at the expense of far‐right parties. The results and extensions exploiting recent advances in political geography, political economy, and spatial econometrics make it possible to draw some general and methodological conclusions. Global drivers interact with elements pertaining to the political supply that empirical researchers should not be oblivious about. Political spillovers across neighboring areas add to the direct impact of locally mediated economic factors. Finally, the adoption of shift–share instrumental variables to identify the impact of robotization may lack robustness.     

Disproportionality and bias in US Presidential Elections: How geography helped Bush defeat Gore but couldn't help Kerry beat Bush

The 2000 and 2004 US Presidential elections were closely fought contests, with in the first case victory in the Electoral College being denied to the candidate with the largest share of the popular vote. Disproportionality in the translation of votes into seats (in this case, from popular votes to votes in the Electoral College) is common to contests using a winner-takes-all electoral system. So is bias, whereby that disproportionality does not apply equally to each candidate. Analysis of the bias at those two elections shows that Bush was favoured at the first but not at the second. Identification of the bias components shows that Bush was advantaged by variations in the number of popular votes per Electoral College voter across the states, and also by variation in turnout. In 2000, his popular votes were also more efficiently distributed than Gore's; in 2004 they were less efficiently distributed than Kerry's, largely because of increased turnout – producing larger numbers of surplus votes – in states that were already safe for Bush.     

A revisionist interpretation of the impact of Queensland's electoral scheme

In December 1989 Queensland voters changed their government from National Party to Labor Party. Labor had been out of office since August 1957, a record period of opposition for a major party. How is that very lengthy Labor period in the wilderness to be explained? The orthodox interpretation is that there has been a gerrymander in Queensland. This article argues, however, that Queensland's electoral system is the same as that of other mainland states. While it is true that electorates are malapportioned in Queensland (and in Western Australia), nevertheless the method of single member electorates with preferential voting is in use for all mainland states. Such a system does not translate a party's percentage of votes into a similar percentage of seats in the Legislative Assembly. The elections of 1956 and 1989 each saw Labor getting a first preference vote in excess of 50 per cent— with which Labor won in excess of 60 per cent of the seats. At no election between these dates did Labor secure a majority of votes, either first preference or two party preferred.     

Russia's Electoral Geography: A Review

A noted specialist on the electoral geography of Russia reviews the existing body of work on the subject based on national elections, beginning with the RSFSR returns from the March 1989 voting for seats in the the USSR Congress of People's Deputies and extending to the presidential race of 2004. The author identifies major themes and methodologies relevant to a discussion of the political topography of Russia, before assessing the extent to which the country's emergent electoral landscape has been described. He emphasizes the importance of scale in interpreting the spatial patterns of electoral outcomes, as well as the social and economic correlates of voting across the regions.

Reaping ‘rewards’ in sickle use-wear analysis

Recently in their research Goodale et al. (2010) as well as that of Vardi et al. (2010) independently tackled issues of effectively measuring attrition/gloss rates on sickle blade tools from Southwest Asia. Interestingly, while applying new methodology to analyzing sickle tools from different cultural and temporal contexts, these two papers arrived at a similar conclusion: sickle tools were likely very expensive to make, and thus, considerations were made during their production to ensure long use-lives to benefit the people who made and used them in prehistory. Stemp et al. (in this issue) provide a methodological critique of both studies. In addressing their critique we make several points. First it is important to note that Stemp et al. provide no new experimental analysis to justify their assertions, and their critique is ultimately, at best, guesswork. Second, the minimal reanalysis of the data Stemp et al. do conduct arguably lead to the same preliminary conclusion at which we originally arrived: the prehistoric sickle blades we examined were used longer than those we replicated. As stated in our original paper, lithic use-wear studies often do not address issue of reliable and reproducible methods. We believe that our original study helps fill this missing component, and that measuring edge thickness is much less subjective than conventional features on stone tools traditionally identified microscopically. From our perspective, Stemp et al. present largely unsupported critical commentary, lacking substantial reanalysis or experiments to complement or justify their commentary. In the end Stemp et al. provide little more than interesting ideas and conjecture.     

Compulsory voting,turnout and party advantage in Australia∗

Who votes or does not vote in a voluntary system has long been thought to have distinct benefits for different political parties. High turnout has been seen as aiding parties of the left, low turnout parties of the right. Although Australia has a compulsory system of voting, this paper shows tha there are still party advantages and disadvantages associated with the 5 percent of the eligible electorate who fail to vote. When turnout is high, Labor makes a net gain in votes, and when turnout is low, the Liberal‐National coalition benefit. Making estimates of nonvoting in Britain and applying them to Australia indicates that this pattern would persist if voluntary voting were applied to Australia, giving the Liberal‐National coalition an inbuilt advantage.
