Mounting evidence suggests that Latin American democracies are characterized by politics and societies becoming more divisive, confrontational, and polarized. This process, which we define here as the “new polarization” in Latin America, seems to weaken the ability of democratic institutions to manage and resolve social and political conflicts. Although recent scholarship suggests that polarization is integral to contemporary patterns of democratic “backsliding” seen in much of the world, this new polarization in the region has not yet received systematic scholarly attention. Aiming to address this gap in the literature, the different contributions in this special issue revise the conceptualization, measurement, and theory of a multidimensional phenomenon such as polarization, including both its ideological and affective dimensions, as well as perspectives at the elite and mass levels of analysis. Findings shed light on the phenomenon of polarization as both a dependent and an independent variable, contributing to comparative literature on polarization and its relationship to democratic governance.

A growing body of literature has focused on how different states continuously “make race” by legitimizing certain racial categories while invisibilizing others. Much less has been written on the actual processes of transforming race into a bureaucratic category when implementing antiracist public policies. This article focuses on the recent use of verification commissions to validate the racial self-identification of potential beneficiaries of racial quotas at federal higher education institutions in Brazil. We argue that through their choices, particularly through their definition of what race is, of who can see race, and of how to see race, these commissions are transforming not only understandings about affirmative action’s aims but also understandings of race. The study focuses on three potential consequences of commission practices for Brazilian racial boundaries: the disciplining of racial identifications, the decontextualization of race, and the individualization of racial injustice.

Defined as a credible threat that strengthens the bargaining position of the executive, presidential vetoes, widely understudied, carry a stigma of confrontation between state powers. But under some institutional setups, partial vetoes can be an additional step in the executive–legislative bargaining process. After a discussion of whether partial vetoes are a proactive legislative tool or a bargaining tool to induce executive–legislative cooperation, we test four hypotheses using the 2,346 bills introduced in Chile between 1990 and 2018 that reached a vetoable stage. We identified 97 partial vetoes (4.2 percent) and one total veto. Presidents are more likely to veto bills with more complex legislative processes and when they have stronger support in at least one chamber, but more popular presidents do not veto more bills. As most presidential vetoes in Chile are partial, they are an additional executive–legislative bargaining step in the lawmaking process rather than evidence of hyperpresidentialism.

Why does the ability of political leaders to control the bureaucracy vary? With strong meritocratic recruitment and tenure protections, Brazil appears an ideal case for successful bureaucratic resistance against political control. However, our analysis reveals how Bolsonaro overcame initial resistance by recalibrating strategies, ultimately dominating many key sectors of the bureaucracy. Drawing on over 100 interviews with public officials, we find that strategies of political control and bureaucratic resistance unfold in a dynamic, yet often predictable, pattern based on leaders' previous experiences and their ability to learn, adjust, and tighten their grip on the instruments of the state. The Bolsonaro administration transformed the regulatory framework and targeted individual state employees, reducing arenas of contestation and inducing public sector workers to remain silent, implementing the president’s policy preferences. We examine these control strategies in environmental agencies, their replication, and potential long-term consequences.

This article offers an analysis of the changes in mass-level ideological polarization in Latin America. It provides a cross-national, region-wide assessment of polarization dynamics using survey data on left-right ideological identities. A novel indicator for measuring ideological polarization at the individual level is proposed, which is more compatible with theoretical conceptualizations of ideological polarization than other existing indicators. The indicator is applied to data from the AmericasBarometer surveys to measure degrees and changes in mass-level ideological polarization in 19 Latin American countries between 2006 and 2019. The study reveals a substantial process of mass-level ideological restructuring, accompanied by a region-wide increase in ideological polarization in Latin America taking place during the second decade of the twenty-first century. We also find that ideological polarization, albeit varying in intensity from country to country, is clearly present at the mass level in the majority of countries in the region.

How do peacebuilding institutions affect political behavior? This article studies the historic victory of the Colombian left in the 2022 presidential elections in light of the implementation of local peacebuilding programs through the 2016 Peace Accords. Using a quasi-experimental design, we show that the Development Plans with a Territorial Focus (PDET), a central component of the 2016 Peace Accords between the government and the FARC, increased the vote share for the leftist coalition, Pacto Histórico, in the 2022 elections by increasing voter turnout in PDET regions. In a departure from existing literature, we find that the explanatory effect of violence on vote share is significantly reduced when we include an indicator for PDET implementation and additional covariates. While there is a substantial body of work examining the effects of conflict violence and the presence of armed actors on elections, there has been relatively little focus on how the peacebuilding has affected vote choice and political behavior. We see our project as a bridge to fill this gap in the literature.

In recent decades, Brazilian voters have grown polarized between supporters of the Partido dos Trabalhadores (Workers’ Party, PT), known as petistas, and its opponents, known as antipetistas. What explains this animosity? One potential source of polarization is partisan stereotyping, a tendency for partisans to misperceive the social composition of both their own side’s bases of support as well as their opponents’. We show that most Brazilians overestimate the extent to which petistas and antipetistas belong to party-stereotypical groups such as Afro-Brazilians, evangelical Christians, or poor or rich people. We then show that stereotyping is associated with polarization: the greater the bias in perceived partisan group composition, the greater the perceptions of partisan political extremism and feelings of social distance toward the partisan out-group.

How do bureaucrats implement public policy when faced with political intermediation? This article examines this issue in the distribution of land rights to informal settlements in the municipality of São Paulo, Brazil. Land regularization is a policy established over three decades, where politicians’ requests for land titles to their constituencies play a relevant role. Based on interviews and documents, this study finds that bureaucrats adopt a twofold approach to regulate distribution: they document informal settlements, enacting eligibility criteria; then, they manage and prioritize beneficiaries, accommodating qualifying political demands. In this process, they enforce eligibility rules consistently across cases, constraining political intermediation to a rational scheme. Therefore, bureaucrats reconcile nonprogrammatic politics and policy rules by separating eligibility assessment from beneficiary selection. This paper bridges urban distributive politics and street-level bureaucracy literature by revealing that policy implementers may use technical expertise to curb political influence and negotiate conflicting interests and constraints.

Regional integration blocs are subject to the admission of new members, which must be approved by domestic institutions. This article analyzes how the incorporation of Venezuela and Bolivia into Mercosur passed in the Paraguayan Congress. While the first case lasted from 2007 to 2013, demonstrating parliamentary opposition, the second episode took place between 2015 and 2016, suggesting convergence between the executive and legislative branches on the issue. Using process tracing, the unveiled mechanism shows how government and opposition forces act to alter the duration of the bill in Congress and that political parties have a pendular behavior according to political cleavages. Moreover, the findings of this study suggest the existence of a parliamentary veto power in foreign affairs and the importance of having homogeneous coalitions to achieve faster approvals.

Conditional cash transfers (CCTs) are a striking case of policy diffusion in Latin America. Almost all countries in the region adopted the model within one decade. While most theories of diffusion focus on the international transference of ideas, this article explains that surge of adoptions by analyzing presidents’ expectations. Out of all ideas transmitted into a country, only a few find their way into enactment and implementation, and the executive has a key role in selecting which ones. Policies expected to boost presidents’ popularity grab their attention. They rapidly enact and implement these models. A process-tracing analysis comparing CCTs and public-private partnerships (PPPs) shows that presidents fast-tracked CCTs hoping for an increase in popular support. Adoptions of PPPs, however, followed normal procedures and careful deliberations because the policy was not expected to quickly affect popularity—which, in the aggregate, leads to a slower diffusion wave.

The emergence of ex-rebels’ political parties after peace accords creates a vehicle for political reintegration, which in turn has positive effects on peace and democracy consolidation after war. However, many of these parties tend to break apart and disappear, elevating the risk of renewed cycles of political violence. In times of war, cohesion plays a pivotal role in maintaining the bonds among members of armed organizations. It empowers them to perform effectively even in the face of challenging conditions and continues to be a critical factor during postconflict transitions. By means of a quantitative analysis of former FARC guerrillas in Colombia, now part of a newly founded legal political party, we test whether ideology, organizational dynamics, or individual perceptions and motivations help to explain their levels of cohesion. Our results show that even if all dimensions add up to the observed cohesion levels, perceptions of internal democracy, and inclusion, are the most relevant. We argue that assistance to former rebels in their organizational reengineering efforts after war will help to reduce the risk of the negative effects of rebel party collapse.

This analytical essay proposes the notion of disjointed polarization to characterize the nature of polarization in contemporary Chile. In disjointed polarization, elite-level polarization does not lead to a successful electoral realignment. Disjointed polarization is thus consistent with a long-lasting crisis of representation in which a serial disconnect between politicians (pursuing different polarizing strategies) and a sizable fraction of the electorate persists, as voters remain alienated from old and emerging political elites. Because the structural changes that make disjointed polarization persist longer than expected in Chile today are widespread across Latin America, the essay speculates on the possibility that enduring disjointed polarization applies to other cases where neither a “populist realignment” nor “generative polarization” took place. Instead, disjointed polarization might reflect the onset of a new (non-partisan representation) normal.

While invalid voting is often treated as protest behavior in an electoral context, its association with actual political protests has not yet been empirically demonstrated. The relative scarcity of research on the topic is likely due to the hybrid nature of invalid voting as a both formal and informal political gesture. The novel availability of event-based data for public protests in Latin America allows for testing whether their occurrence is connected with changes in spoiled and blank ballots. Using an appropriate dynamic regression model covering variations in the 148 intervals between Latin American legislative elections in the 1979–2021 period, this study finds a strong connection between the emergence of antigovernment protests and surges in invalid voting (and vice versa). This relationship still holds at parity of economic conditions and it is reinforced by a lack of alternation in the party of power. Conversely, the appearance of workers’ strikes appears to work as a substitute for this behavior, which is also chosen by voters when democracy deteriorates, while corruption has no independent impact on invalid voting. Overall this work’s findings promise to send the research agenda on invalid voting in a new direction, previously unexplored because of an absence of fitting data.

This article examines bureaucracies using a novel dataset of Chilean central government employees from 2006 to 2020. Unlike perception-based sources, this dataset provides objective, disaggregated, and longitudinal insights into bureaucrats’ characteristics and careers. The authors validate it against official employment statistics and conduct an exploratory and descriptive analysis, presenting six descriptive findings about the Chilean bureaucracy that cannot be discovered using available aggregate data. The analysis reveals significant degrees of personnel stability and professionalization in the civil service, but with considerable rigidity in careers and substantial interagency heterogeneity in turnover, wages, and exposure to political cycles. These findings suggest that the Chilean national bureaucracy is mostly well developed along Weberian lines, though not uniformly so. These measurements also serve as a benchmark for comparing other Latin American bureaucracies in the future.

The ideational definition of populism proposes that a narrative is populist if it is characterized by a Manichean cosmology that divides the political community between a “people,” conceived as a homogeneously virtuous entity, and an “elite,” conceived as a homogeneously corrupt entity. Departing from that conceptualization, this work first investigates the specific stories that Andrés Manuel López Obrador uses to spread his populist worldview, which we call “storytelling.” We define the idea of storytelling as the art of telling a story where emotions, characters and other details are applied in order to promote a particular point of view or set of values. Second, we explore whether some of those stories produce greater negative affective polarization, here defined as the extent to which rival sociopolitical camps view each other as a disliked out-group. Findings suggest that some specific stories—in particular, what we call “stories of conspiracy” and “stories of ostracism”—indeed tend to induce more polarized attitudes among citizens.

This article studies the influence of the antineoliberal social movements in Peru and Ecuador in the face of the Multiparty Trade Agreement (MTA) between both countries and the European Union (EU). To identify and analyze this influence, a transdisciplinary theoretical framework was created, integrating debates and concepts from social movement theory and critical international political economy. In Peru, the movement used European allies to establish their demands on the EU’s agenda, which resulted in increased pressure on the government to enforce labor rights and environmental standards. In Ecuador, the movement was able to establish food sovereignty and the rejection of free trade in the national constitution. As a result, the negotiations with the EU were delayed and Ecuador achieved certain exceptions in its adhesion protocol. Nevertheless, both movements were unable to maintain their influence, due to political and socioeconomic dynamics on the domestic and global levels.

Generalizability of extant findings about media treatment of women in politics is uncertain because most research examines candidates for the legislature or heads of government, and little work moves beyond Anglo-American countries. We examine six presidential cabinets in Costa Rica, Uruguay, and the United States, which provide differing levels of women’s incorporation into government. These cases permit us to test hypotheses arguing that differences in media treatment of men and women cabinet ministers will decrease as women’s inclusion in government expands, and that media treatment of women is more critical when women head departments associated with masculine gender stereotypes. Results show that greater incorporation of women into government is associated with fewer gendered differences in media coverage, tone of minister coverage is more favorable for women who hold masculine stereotyped portfolios, and that the media does present qualifications of women cabinet ministers.

Polarizing rhetoric and negative tone are thought to generate more attention on social media. We seek to describe and analyze how presidential candidates in Colombia’s 2022 election deployed (de)polarizing rhetoric and tone, around what topics, and with what effects. We analyze the tweets (and corresponding engagement) of the four leading candidates during the campaign. Tone behaves as expected. Negatively worded tweets receive overall more likes and retweets, though the strength of their effect varies by candidate. Polarizing rhetoric behaves differently. Using polarizing and depolarizing rhetoric proved better than neutral messages, but using depolarizing rhetoric, generated greater engagement than its polarizing counterpart. This study suggests that the visibility of a candidate does not necessarily correspond to their greater use of Twitter, an increased deployment of polarizing rhetoric, or an emphasis on negative emotions. This article provides a glimmer of hope regarding the potential usefulness of positive uniting messages on Twitter (now X).

Political polarization is a systemic-level and multifaceted process that severs cross-cutting ties and shifts perceptions of politics to a zero-sum game. When it turns pernicious, political actors and supporters view opponents as an existential threat and the capacity of democratic institutions to process political conflict breaks down. The article identifies four common fault lines of polarization globally – who belongs, democracy, inequality and social contract. It argues that while Latin American countries experience, to varying degrees, all four of the fault lines, it is the deep-seated, persistent social hierarchies oriented around class, race, and place that stand out relative to other countries. Reaching consensus on reforms that may renew or reformulate agreements on the terms of the social contract, boundaries of community membership, and redressing social inequality is a tall task. Yet the region’s sustained consensus on the democratic rules of the game can provide the mechanisms for addressing this task if new majority coalitions can be formed.

This essay documents growing partisan social uprootedness across Latin America over time, manifested in diminishing social trust toward parties, debilitation of links between parties and social collectivities, lowering levels of partisanship, and rising incidence of personalism in the electorate. It focuses on some unrecognized and undertheorized causal factors behind partisan involution in the region, putting emphasis on mutually reinforcing processes. First, it identifies forces endogenous to the traits of origin of diminished parties that foster their uprootedness and decay; second, it lays out some of the manifold ways that the weakening of political parties fuels regime malperformance, in a mutually reinforcing vicious circle; third, it outlines the existence of mutual feedback loops between political agency and structure; fourth, it identifies various agential sources of party decay. There are strong theoretical and empirical reasons to expect continued party deinstitutionalization across Latin America going forward.
