Legislator Success in Fragmented Congresses in Argentina : Plurality Cartels, Minority Presidents, and Lawmaking

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.

Extensive gatekeeping authority without plenary majorities, this book shows, leads to policy outcomes that are substantially different from those observed in majority-led congresses.
