Dinâmica partidária eleitoral: subsistemas municipais de Mato Grosso

Abstract

In order to fill a gap in the available Political Science literature, this thesis aims to investigate the party-electoral system of the State of Mato Grosso, Brazil, from 1988 to 2016. We have described the Mato Grosso partisan subsystem, verifying partisan fragmentation and the effective number of parties and the evolution of municipal electoral competition (1996 to 2012) at the national level, drawing comparative lines between the two. The levels of fractionalization and the effective number of parties are based on data the data of elections from 1988 to 2016, wich were made available by the Regional Electoral Tribunal and Superior Electoral Court. In the comparative analysis between the are numbers that actually allow a more complete knowledge of the electoral and partisan reality. The dispersion or concentration of votes and positions between parties is one of the central features in the discussions of political systems. Considering the context of the political dynamics in the State of Mato Grosso, we also consider the evaluation of the dispersion and concentration of votes and seats among political parties in municipal elections for councilors and mayors. We acknowledge, in this research scenario, the factoring rates and actual number of parties, both calculated based by votes and seats.
