Abstract

Proportional elections (deputies) held in Brazil obey a power-law regime, that is, the distribution of the number of candidates N receiving a fraction of votes v followed a negative power law N(v)≈va, where a≈-1. Here, majority (presidential) elections were studied. Results show that in majority elections, negative power law regime defines losers and positive power law regime defines winners. In case of tight elections, these differences are reduced.

Keywords: voter network, proportional election, majority election
