Party-System Collapse

The Roots of Crisis in Peru and Venezuela

by Jason Seawright

Most party systems are relatively stable over time. Yet in the 1980s and 1990s, established party systems in Peru and Venezuela broke down, leading to the elections of outsider Alberto Fujimori and anti-party populist Hugo Chavez. Focusing on these two cases, this book explores the causes of systemic collapse.

To date, scholars have pointed to economic crises, the rise of the informal economy, and the charisma and political brilliance of Fujimori and Chavez to explain the changes in Peru and Venezuela. This book uses economic data, surveys, and experiments to show that these explanations are incomplete. Political scientist Jason Seawright argues that party-system collapse is motivated fundamentally by voter anger at the traditional political parties, which is produced by corruption scandals and failures of representation. Integrating economic, organizational, and individual considerations, Seawright provides a new explanation and compelling new evidence to present a fuller picture of voters' decisions and actions in bringing about party-system collapse, and the rise of important outsider political leaders in South America.

In The Press

"Seawright frames an intriguing question. Why did the party system, in the context of economic difficulties, collapse in Peru and Venezuela, while pressing economic problems in Argentina in 2001 did not produce the same results? The author attributes the phenomenon to voter anger over corruption and the failure of the established political parties to represent their viewpoints on the ideological spectrum. In contrast, Argentina's Peronist party adapted to the new political landscape after the failure of neoliberalism, and consequently the nation averted party breakdown. Seawright grounds his conclusions on a wealth of empirical evidence. This book is comparative politics at its best."
