Competition is a defining element of democracy. One of the most noteworthy events over the last quarter-century in U.S. politics is the change in the nature of elite party competition: The parties have become increasingly polarized. Scholars and pundits actively debate how these elite patterns influence polarization among the public (e.g., have citizens also become more ideologically polarized?). Yet, few have addressed what we see as perhaps more fundamental questions: Has elite polarization altered the way citizens arrive at their policy opinions in the first place and, if so, in what ways? We address these questions with a theory and two survey experiments (on the issues of drilling and immigration). We find stark evidence that polarized environments fundamentally change how citizens make decisions. Specifically, polarization intensifies the impact of party endorsements on opinions, decreases the impact of substantive information and, perhaps ironically, stimulates greater confidence in those—less substantively grounded—opinions. We discuss the implications for public opinion formation and the nature of democratic competition.

Democratic states are in general about as conflict- and war-prone as nondemocracies, but democracies have rarely clashed with one another in violent conflict. We first show that democracy, as well as other factors, accounts for the relative lack of conflict. Then we examine two explanatory models. The normative model suggests that democracies do not fight each other because norms of compromise and cooperation prevent their conflicts of interest from escalating into violent clashes. The structural model asserts that complex political mobilization processes impose institutional constraints on the leaders of two democracies confronting each other to make violent conflict unfeasible. Using different data sets of international conflict and a multiplicity of indicators, we find that (1) democracy, in and of itself, has a consistent and robust negative effect on the likelihood of conflict or escalation in a dyad; (2) both the normative and structural models are supported by the data; and (3) support for the normative model is more robust and consistent.

Framing is the process by which a communication source, such as a news organization, defines and constructs a political issue or public controversy. Two experiments examined the effect of news frames on tolerance for the Ku Klux Klan. The first presented research participants with one of two local news stories about a Klan rally that varied by frame: One framed the rally as a free speech issue, and the other framed it as a disruption of public order. Participants who viewed the free speech story expressed more tolerance for the Klan than participants who watched the public order story. Additional data indicate that frames affect tolerance by altering the perceived importance of public order values. The relative accessibility of free speech and public order concepts did not respond to framing. A second experiment used a simulated electronic news service to present different frames and replicated these findings.

We report the results of a randomized field experiment involving approximately 30,000 registered voters in New Haven, Connecticut. Nonpartisan get-out-the-vote messages were conveyed through personal canvassing, direct mail, and telephone calls shortly before the November 1998 election. A variety of substantive messages were used. Voter turnout was increased substantially by personal canvassing, slightly by direct mail, and not at all by telephone calls. These findings support our hypothesis that the long-term retrenchment in voter turnout is partly attributable to the decline in face-to-face political mobilization.

This paper develops a game-theoretic approach to the problem of political officials' respect for political and economic rights of citizens. It models the policing of rights as a coordination problem among citizens, but one with asymmetries difficult to resolve in a decentralized manner. The paper shows that democratic stability depends on a self-enforcing equilibrium: It must be in the interests of political officials to respect democracy's limits on their behavior. The concept of self-enforcing limits on the state illuminates a diverse set of problems and thus serves as a potential basis for integrating the literature. The framework is applied to a range of topics, such as democratic stability, plural societies, and elite pacts. The paper also applies its lessons to the case of the Glorious Revolution in seventeenth-century England.

Scholars routinely make claims that presuppose the validity of the observations and measurements that operationalize their concepts. Yet, despite recent advances in political science methods, surprisingly little attention has been devoted to measurement validity. We address this gap by exploring four themes. First, we seek to establish a shared framework that allows quantitative and qualitative scholars to assess more effectively, and communicate about, issues of valid measurement. Second, we underscore the need to draw a clear distinction between measurement issues and disputes about concepts. Third, we discuss the contextual specificity of measurement claims, exploring a variety of measurement strategies that seek to combine generality and validity by devoting greater attention to context. Fourth, we address the proliferation of terms for alternative measurement validation procedures and offer an account of the three main types of validation most relevant to political scientists.

Political machines (or clientelist parties) mobilize electoral support by trading particularistic benefits to voters in exchange for their votes. But if the secret ballot hides voters' actions from the machine, voters are able to renege, accepting benefits and then voting as they choose. To explain how machine politics works, I observe that machines use their deep insertion into voters' social networks to try to circumvent the secret ballot and infer individuals' votes. When parties influence how people vote by threatening to punish them for voting for another party, I call this accountability. I analyze the strategic interaction between machines and voters as an iterated prisoners' dilemma game with one-sided uncertainty. The game generates hypotheses about the impact of the machine's capacity to monitor voters, and of voters' incomes and ideological stances, on the effectiveness of machine politics. I test these hypotheses with data from Argentina.

What accounts for variation in the electoral success of niche parties? Although institutional and sociological explanations of single-issue party strength have been dominant, they tend to remove parties from the analysis. In this article, I argue that the behavior of mainstream parties influences the electoral fortunes of the new, niche party actors. In contrast to standard spatial theories, my theory recognizes that party tactics work by altering the salience and ownership of issues for political competition, not just party issue positions. It follows that niche party support can be shaped by both proximal and non-proximal competitors. Analysis of green and radical right party vote in 17 Western European countries from 1970 to 2000 confirms that mainstream party strategies matter; the modified spatial theory accounts for the failure and success of niche parties across countries and over time better than institutional, sociological, and even standard spatial explanations.

In ethnic and racial terms, America is growing rapidly more diverse. Yet attempts to extend racial threat hypotheses to today's immigrants have generated inconsistent results. This article develops the politicized places hypothesis, an alternative that focuses on how national and local conditions interact to construe immigrants as threatening. Hostile political reactions to neighboring immigrants are most likely when communities undergo sudden influxes of immigrants and when salient national rhetoric reinforces the threat. Data from several sources, including twelve geocoded surveys from 1992 to 2009, provide consistent support for this approach. Time-series cross-sectional and panel data allow the analysis to exploit exogenous shifts in salient national issues such as the September 11 attacks, reducing the problem of residential self-selection and other threats to validity. The article also tests the hypothesis using new data on local anti-immigrant policies. By highlighting the interaction of local and national conditions, the politicized places hypothesis can explain both individual attitudes and local political outcomes.

The institutional grammar introduced here is based on a view that institutions are enduring regularities of human action in situations structured by rules, norms, and shared strategies, as well as by the physical world. The rules, norms, and shared strategies are constituted and reconstituted by human interaction in frequently occurring or repetitive situations. The syntax of the grammar identifies components of institutions and sorts them into three types of institutional statements: rules, norms, and shared strategies. We introduce the grammar, outline methods for operationalizing the syntax, apply the syntax to an analysis of cooperation in collective dilemma situations, and discuss the pragmatics of the grammar for analyses of behavior within complex institutional settings.

We present a new way of extracting policy positions from political texts that treats texts not as discourses to be understood and interpreted but rather, as data in the form of words. We compare this approach to previous methods of text analysis and use it to replicate published estimates of the policy positions of political parties in Britain and Ireland, on both economic and social policy dimensions. We “export” the method to a non-English-language environment, analyzing the policy positions of German parties, including the PDS as it entered the former West German party system. Finally, we extend its application beyond the analysis of party manifestos, to the estimation of political positions from legislative speeches. Our “language-blind” word scoring technique successfully replicates published policy estimates without the substantial costs of time and labor that these require. Furthermore, unlike in any previous method for extracting policy positions from political texts, we provide uncertainty measures for our estimates, allowing analysts to make informed judgments of the extent to which differences between two estimated policy positions can be viewed as significant or merely as products of measurement error.We thank Raj Chari, Gary King, Michael McDonald, Gail McElroy, and three anonymous reviewers for comments on drafts of this paper.

Corruption, some say, is endemic in all governments. Yet it has received remarkably little attention from students of government. Not only is the study of corruption prone to moralism, but it involves one of those aspects of government in which the interests of the politician and the political scientist are likely to conflict. It would probably be rather difficult to obtain (by honest means) a visa to a developing country which is to be the subject of a corruption study.

One of the first charges levelled at the previous regime by the leaders of the coup in the less developed country is “corruption.” And generally the charge is accurate. One type of reaction to this among observers is highly moralistic and tends to see corruption as evil. “Throughout the fabric of public life in newly independent States,” we are told in a recent work on the subject, “runs the scarlet thread of bribery and corruption …” which is like a weed suffocating better plants. Another description of new states informs us that “corruption and nepotism rot good intentions and retard progressive policies.”

Others have reacted against this moralistic approach and warn us that we must beware of basing our beliefs about the cause of coups on post-coup rationalizations, and also of judging the social consequences of an act from the motives of the individuals performing it. Under some circumstances Mandeville is right that private vice can cause public benefit.

With tenacious regularity over the last two and a half decades the Gallup Poll has posed to its cross-section samples of the American public the following query, “Do you approve or disapprove of the way (the incumbent) is handling his job as President?” The responses to this curious question form an index known as “Presidential popularity.” According to Richard Neustadt, the index is “widely taken to approximate reality” in Washington and reports about its behavior are “very widely read” there, including, the quotation above would suggest, the highest circles.

Plotted over time, the index forms probably the longest continuous trend line in polling history. This study seeks to analyze the behavior of this line for the period from the beginning of the Truman administration in 1945 to the end of the Johnson administration in January 1969 during which time the popularity question was asked some 300 times.

Four variables are used as predictors of a President's popularity. These include a measure of the length of time the incumbent has been in office as well as variables which attempt to estimate the influence on his rating of major international events, economic slump and war. To assess the independent impact of each of these variables as they interact in association with Presidential popularity, multiple regression analysis is used as the basic analytic technique.

This paper examines the bases of opposition to immigrant minorities in Western Europe, focusing on The Netherlands. The specific aim of this study is to test the validity of predictions derived from two theories—realistic conflict, which emphasizes considerations of economic well-being, and social identity, which emphasizes considerations of identity based on group membership. The larger aim of this study is to investigate the interplay of predisposing factors and situational triggers in evoking political responses. The analysis is based on a series of three experiments embedded in a public opinion survey carried out in The Netherlands (n=2007) in 1997–98. The experiments, combined with parallel individual-level measures, allow measurement of the comparative impact of both dispositionally based and situationally triggered threats to economic well-being and to national identity at work. The results show, first, that considerations of national identity dominate those of economic advantage in evoking exclusionary reactions to immigrant minorities and, second, that the effect of situational triggers is to mobilize support for exclusionary policies above and beyond the core constituency already predisposed to support them.

National survey data demonstrate that support of the federal government decreased substantially between 1964 and 1970. Policy preference, a lack of perceived difference between the parties, and policy dissatisfaction were hypothesized as correlates of trust and alternative explanations of this decrease. Analysis revealed that the increased distrust in government, or cynicism, was associated with reactions to the issues of racial integration and U.S. involvement in the Vietnam war. A curvilinear relationship was found between policy preference on these and other contemporary social issues and political cynicism. The minority favoring centrist policies was more likely to trust the government than the large proportion who preferred noncentrist policy alternatives. This complex relationship between trust and policy preference is explained by dissatisfaction with the policies of both political parties. The dissatisfied noncentrists formed highly polarized and distinct types: “cynics of the left,” who preferred policies providing social change, and “cynics of the right,” who favored policies of social control.

Allusions to the “problem of metropolitan government” are often made in characterizing the difficulties supposed to arise because a metropolitan region is a legal non-entity. From this point of view, the people of a metropolitan region have no general instrumentality of government available to deal directly with the range of problems which they share in common. Rather there is a multiplicity of federal and state governmental agencies, counties, cities, and special districts that govern within a metropolitan region.

This view assumes that the multiplicity of political units in a metropolitan area is essentially a pathological phenomenon. The diagnosis asserts that there are too many governments and not enough government. The symptoms are described as “duplication of functions” and “overlapping jurisdictions.” Autonomous units of government, acting in their own behalf, are considered incapable of resolving the diverse problems of the wider metropolitan community. The political topography of the metropolis is called a “crazy-quilt pattern” and its organization is said to be an “organized chaos.” The prescription is reorganization into larger units—to provide “a general metropolitan framework” for gathering up the various functions of government. A political system with a single dominant center for making decisions is viewed as the ideal model for the organization of metropolitan government. “Gargantua” is one name for it.

This article compares two theories of human rationality that have found application in political science: procedural, bounded rationality from contemporary cognitive psychology, and global, substantive rationality from economics. Using examples drawn from the recent literature of political science, it examines the relative roles played by the rationality principle and by auxiliary assumptions (e.g., assumptions about the content of actors' goals) in explaining human behavior in political contexts, and concludes that the model predictions rest primarily on the auxiliary assumptions rather than deriving from the rationality principle.

The analysis implies that the principle of rationality, unless accompanied by extensive empirical research to identify the correct auxiliary assumptions, has little power to make valid predictions about political phenomena.

Debates about globalization have centered on calls to improve accountability to limit abuses of power in world politics. How should we think about global accountability in the absence of global democracy? Who should hold whom to account and according to what standards? Thinking clearly about these questions requires recognizing a distinction, evident in theories of accountability at the nation-state level, between “participation” and “delegation” models of accountability. The distinction helps to explain why accountability is so problematic at the global level and to clarify alternative possibilities for pragmatic improvements in accountability mechanisms globally. We identify seven types of accountability mechanisms and consider their applicability to states, NGOs, multilateral organizations, multinational corporations, and transgovernmental networks. By disaggregating the problem in this way, we hope to identify opportunities for improving protections against abuses of power at the global level.

We develop a Bayesian procedure for estimation and inference for spatial models of roll call voting. This approach is extremely flexible, applicable to any legislative setting, irrespective of size, the extremism of the legislators' voting histories, or the number of roll calls available for analysis. The model is easily extended to let other sources of information inform the analysis of roll call data, such as the number and nature of the underlying dimensions, the presence of party whipping, the determinants of legislator preferences, and the evolution of the legislative agenda; this is especially helpful since generally it is inappropriate to use estimates of extant methods (usually generated under assumptions of sincere voting) to test models embodying alternate assumptions (e.g., log-rolling, party discipline). A Bayesian approach also provides a coherent framework for estimation and inference with roll call data that eludes extant methods; moreover, via Bayesian simulation methods, it is straightforward to generate uncertainty assessments or hypothesis tests concerning any auxiliary quantity of interest or to formally compare models. In a series of examples we show how our method is easily extended to accommodate theoretically interesting models of legislative behavior. Our goal is to provide a statistical framework for combining the measurement of legislative preferences with tests of models of legislative behavior.

With which political and economic variables is change in international financial regulation robustly associated? I undertook multivariate regression analysis of this question using a quantitative measure of the regulation of international financial transactions. The measure was created by coding the laws of 64 nations. The associations between change in international financial regulation and measures of long-run economic growth, corporate taxation, government expenditures, and income inequality are estimated, using the models, methods, and data of Batro (1991), Deininger and Squire (1996a), Leamer (1983, 1985), and Levine and Renelt (1992). The findings point to a new agenda for research on international financial regulation.
