The article discusses the process of institutionalization of political parties in Brazil in the post-redemocratization period. The advent of the Worker's Party (PT), and its electoral disputes with the Brazilian Social Democracy Party (PSDB) point to an ongoing yet unaccomplished process: the emergence, in the orbit of both parties, of stable political-partidary identifications that could lead to a simplified and consolidated party system and the neutralization of the success of the excessively clientelistic and pragmatic orientation that characterizes Brazilian Democratic Movement Party's (PMDB) feeble regional roots.
