Using the United States as a basis of comparison, this book, first published in 2004, makes extensive use of roll call data to explore patterns of legislative politics in Argentina, Brazil, Chile and Uruguay. It distinguishes among parties, factions, coalitions and delegations based on the extent to which they are unified in their voting and/or willing to form policy coalitions with other legislative 'agents'. It discusses the voting unity and ballot systems that allow voters to identify an agent, and describes the degree to which those agents have been flexible with regards to the formation of policy coalitions. It also shows that the US parties have exhibited higher levels of unity but less flexibility in recent years, and thus contrast the prevailing pattern in Latin America. The book focuses its explanation for the patterns on the role of candidate nominations, other aspects of the electoral system and the legislators' ideological alignments.
• Single-authored volume • Explicit comparisons about the level of unity and the patterns of coalitions in the Latin American and US legislatures • Extends study to sub- and supra-party groups
