Brazil is a federative republic with a political system composed of three levels of independent government (federal government, 26 states and one federal district, and 5,563 municipalities). The government is led by a president (executive branch), bicameral legislature (chamber of deputies and senate house) and several political parties. Brazil is a democratic nation, governed by means of an independent judiciary, with national and subnational (mandatory voting) electronic elections every four years (Paim et al., 2011). It is a young democracy, still with many contradictions.
