In 2015, a center-left government introduced an electoral reform that replaced the binomial electoral system governing parliamentary elections since 1989 with a more proportional system. This article provides an account of the reform process, describes the new electoral law, and discusses the factors explaining the reform. We argue, first, that it was possible, due to the incentives the government provided, to secure the support of an ample majority of parliamentarians; also, a new and favorable political scenario had emerged, in which the support of the main right-wing parties was not necessary for the reform to pass. Second, we maintain that the reform sought mainly to resolve problems affecting the parties of the governing coalition related to negotiations of coalition lists for elections. As a complementary objective, the reform promoted a general interest by establishing rules that allowed a “fairer” system of representation and improved competitive conditions.

Theoretically based on Albert O. Hirschman's Exit, Voice, and Loyalty, this study examines three cases of rupture or exit by Mexican presidential contenders, in 1940, 1952, and 1988, and one “noncase,” in 1999, with a view to how dissidents' strategies shape political institutions. Mexico's PRI-dominated political system depended on its leaders' ability to create an equilibrium based on mutual incentives to remain loyal to the regime.

Party machines and brokers have been widely researched in political science since 1950, yet a full description of brokers' roles is still missing. This article contributes by describing in detail the many roles brokers perform for their parties and explaining why each broker performs all these roles. In particular, it shows that besides fulfilling clientelistic strategies, brokers perform important executive governability functions once their party is in power. Brokers multitask because they have the neighborhood knowledge required to successfully perform political activities at the local level. Moreover, performing nonclientelistic roles prepares brokers to perform clientelistic strategies. The article also presents a novel theoretical account for why voters abide by the clientelistic deal. Based on interviews with 120 brokers, it analyzes the complete set of brokers' strategies, and detailed narrative accounts show the clientelistic machine at work.

Problems of unity can affect an armed opposition group at many stages of its existence—during the war, in peace negotiations, and in its transition to political party. This article assesses how internal divisions affected the performance of the Farabundo Martí National Liberation Front (FMLN) in El Salvador. It finds that while the FMLN suffered significant internal divisions in the early years of the war, it remained remarkably unified from 1983 on. Significant divisions began to appear during the later war years but were not exacerbated until after the war's conclusion, when repeated fracturing occurred. The FMLN began to present itself as a programmatically coherent party only in 2005, and this ideological homogeneity allowed it to establish a series of partnerships with moderate, non-revolutionary sectors of Salvadoran society and to achieve victory in the 2009 presidential elections.

This study aims to explain the victory of Hugo Chávez and his party in the 2000 Venezuelan elections, to analyze the factors that made this victory possible, and to examine the consequences for future developments in the Venezuelan political system. The decay of traditional party loyalties without the emergence of new parties deeply rooted in society (dealignment without realignment); underdevelopment; and an institutional setting dominated by a president elected by a plurality electoral system have opened the door to personality-centered politics and weak parties, which are the main features of the current political situation. Compared to the 1993 and 1998 elections, the 2000 elections once again confirm an increase in personality politics and the decay of parties as instruments for articulating interests, representation, and governance. As a consequence, this article argues, instability is likely to remain a feature of Venezuela's party system for some time.

This article assesses how much the emergence of civil society and private market activities are challenging Cuba's ruling communist regime. The assessment is based on a conceptualization of a “civil sphere,” constituted by civil society and private market activities (or the “second economy”), and how this affects democratic transitions from state-socialist societies, using Cuba as a case study. Examining the multiple sectors at play reveals an increasingly organized and vocal opposition, but one hampered by continued government repression. Considering several theoretical and historically possible scenarios, this study concludes that under current conditions, the civil sphere's significant challenge is still not enough for a regime change in the Cuban state.
