Plurality-led congresses are among the most pervasive and least studied phenomena in presidential systems around the world. Often conflated with divided government, where an organized opposition controls a majority of seats in congress, plurality-led congresses are characterized by a party with fewer than fifty percent of the seats still in control of the legislative gates. Extensive gatekeeping authority without plenary majorities, this book shows, leads to policy outcomes that are substantially different from those observed in majority-led congresses. Through detailed analyses of legislative success in Argentina and Uruguay, this book explores the determinants of law enactment in fragmented congresses. It describes in detail how the lack of majority support explains legislative success in standing committees, the chamber directorate, and on the plenary floor.

Calvo and Murillo consider the non-policy benefits that voters consider when deciding their vote. While parties advertise policies, they also deliver non-policy benefits in the form of competent economic management, constituency service, and patronage jobs. Different from much of the existing research, which focuses on the implementation of policy or on the delivery of clientelistic benefits, this book provides a unified view of how politicians deliver broad portfolios of policy and non-policy benefits to their constituency. The authors' theory shows how these non-policy resources also shape parties' ideological positions and which type of electoral offers they target to poorer or richer voters. With exhaustive empirical work, both qualitative and quantitative, the research documents how linkages between parties and voters shape the delivery of non-policy benefits in Argentina and Chile.
