The central question of this article is why indigenous social movements formed electorally viable political parties in Latin America in the 1990s. This development represents a new phenomenon in Latin America, where ethnic parties have been both rare and unpopular among voters. Institutional reforms in six South American countries are examined to see if the creation and success of these parties can be correlated with changes in electoral systems, political party registration requirements, or the administrative structure of the state. The study concludes that institutional change is likely to be a necessary but not sufficient condition for the emergence and electoral viability of ethnic parties.

Since 1999, women have democratically won the presidency eight times in Latin America and have named hundreds of ministers. This study argues that under certain conditions, presidentas are more likely than male presidents to improve women's cabinet representation. Two mechanisms, presidenta mandates and gendered networks, appear to drive the relationship. Furthermore, because the pool of ministerial candidates is shallower for women than for men, presidentas are most likely to advance women's representation in cabinets at the beginning of their term and for “feminine” ministries. A case study of Michelle Bachelet's 2006 ministerial appointments reveals initial evidence for the argument. Empirical implications are then tested with an original dataset of 1,908 ministers of all democratically elected Latin American presidents since 1999. Model results are consistent with the theory that presidentas are most likely to “make a difference” when they are least constrained by the supply of female ministerial candidates.

This article analyzes Luiz Inácio da Silva's resounding reelection victory in the wake of corruption scandals implicating his party and government. Voters with lower levels of economic security and schooling played a critical role in returning Lula to the presidency. Least prone to punish the president for corruption, poorer Brazilians were also the most readily persuaded by the provision of material benefits. Minimum wage increases and the income transfer program Bolsa Família expanded the purchasing power of the poor. Thus, executive power and central state resources allowed Lula to consolidate a social base that had responded only weakly to his earlier, party-based strategy of grassroots mobilization for progressive macrosocietal change. Although Lula won handily, the PT's delegation to Congress shrank for the first time, and the voting bases of president and party diverged. The PT benefited far less than the president himself from government investment in social policy.

A set of discussion groups including leftist ex-guerrillas and rightist ex-paramilitaries in Colombia shows the limits for democratic deliberation in postconflict societies, but also points to ways that outcomes closer to the deliberative ideal might be obtained. A total of 342 ex-combatants agreed to sit down and talk politics under a number of experimental conditions, using three different protocols of engagement. Results show that consensus rule fosters simultaneously a more reasoned and common-good–oriented, and less self-interested type of discussion when compared to majority rule and unstructured “free talk.” Nevertheless, while it might be desirable to promote a better quality of deliberation in divided societies, it does not necessarily prevent antagonists’ tendency to polarize.

Are party switchers successful at furthering their careers? Most research on party switching focuses on the decision to switch and with which party to affiliate. Less attention is paid to the costs and benefits of switching parties. Moreover, previous research examining the electoral success of party switchers has often ignored how costs vary between the candidate selection process and the general election. This study addresses this gap in the literature by using original data on the careers of Mexican federal deputies to examine the costs and benefits of switching parties at the candidate selection stage and during general elections. The results suggest that party switchers are more successful at winning ballot access than nonswitchers but are less likely to win office. These results help explain why ambitious politicians would switch parties, given the known risks of changing party affiliation.

The experiences of communities in Rio de Janeiro under threat of removal through gentrification or mega-event construction present an opportunity to review the process and impact of urban community mobilization. This article assesses the determinants of community strategies, the challenges to implementation, and the impact of mobilization on outcomes for such communities. It reviews the case of Vila Autódromo, detailing the dynamic influence of both rational expectations and the “right to the city” ideology in developing resistance strategies and providing evidence to confirm the importance of social capital and civic capacity for community efficacy. The analysis updates theorizing beyond the politics of clientelism and contributes to understanding how the urban regime approach may apply to the Latin American context, while demonstrating the continued relevance of the political opportunity structure for determining policy outcomes.

This article analyzes how market reform policies already in place affect social interests, and the feedback effects of those interests on reform processes. The variety of societal responses includes the creation of new societal organizations, reflecting the variable content and asymmetrical distribution of costs and benefits of the policies implemented. Because of this variety even in Peru, where the disorganizing effects of neoliberal reform appear to be strongest, it would seem that the societal impact of economic reform elsewhere in Latin America would also warrant more careful examination.
