Brazilian elections: voting for a scaling democracy
R. N. Costa Filho, M. P. Almeida, J. E. Moreira, J. S. Andrade Jr

TL;DR
This paper analyzes the statistical patterns of Brazilian elections in 1998 and 2002, revealing a power-law distribution in votes that suggests a multiplicative process influences voter behavior.
Contribution
It introduces the idea that voter choice follows a multiplicative probabilistic process, explaining the observed scaling invariance in election data.
Findings
Vote distributions follow a power-law pattern.
Scaling invariance persists across different election years.
Voter choice modeled as a multiplicative process.
Abstract
The proportional elections held in Brazil in 1998 and 2002 display identical statistical signatures. In particular, the distribution of votes among candidates includes a power-law regimen. We suggest that the rationale behind this robust scaling invariance is a multiplicative process in which the voter's choice for a candidate is governed by a product of probabilities.
