The Superior Electoral Court anticipated the political reform with the creation of party loyalty, reproduced in infra constitutional legislation by Law n°. 13.165/2015. The change in the electoral system allows imagine the foundation of a State Parties in Brazilian democracy. Although most constitutions incorporate the virtual mandate idea, or representative, according thought of Burke and Sieyes, the democratic legitimacy requires control mechanisms and accountability of representatives to the population, including legal. It takes up to the imperative mandate, not in Rousseauian molds, but tied to party guidelines, founding party mandates. The ownership of the mandate by the political party moves towards the strengthening of key players who are partisan associations in the electoral process. On the other hand, it is not obvious that political parties meet the necessary conditions for the establishment of an imperative mandate tied to party deliberations, since patent oligarchic and bureaucratic character of much of them, whose process of deliberation and choice of leaders and political positions do not require internal democracy. This reflection induces the political and party system to wonder if the role they playing in democracy helps to combat political inequality or strength it, by analyzing the dynamics of party migration in Brazil.
