Estrutura da competi？？o pela Presidência e consolida？？o do sistema partidário no Brasil

in this article, the authors: (1) argue that the structure of the brazilian presidential race represents the decisive factor in the recent consolidation of the country's party system; (2) identify three distinct party blocs based on an analysis of the strategies developed by the parties within the presidential race; (3) examine the blocs' positions based on surveys conducted in the chamber of deputies in 2005 and 2010; and (4) demonstrate that the situation in the electoral sphere has its correlate at the congressional level, allowing an ideological distinction between two of these blocs, while the third bloc calculates its moves exclusively on the disconnect between government and opposition.
