The research herein deals with the theories of political representation as they are exposed by Bernard Manin, Pierre Rosanvallon and Nadia Urbina ti, considering the perspective of a tense existing relationship between democracy and political representation, as it was recovered by Bernard Manin. There is a rhetoric that follows the universal suffrage adoption in which it is seen as a solution to the tense relationship among political representation and democracy, what has led general understanding of representative institutionality to be surrounded by superstitions regarding its mechanisms effectiveness and responsiveness. It is possible to approximate the three studied theorists if political representation is inquired as a process that mediates these tensions between political and social spheres. The question is that for both former authors, the political representation process is pre-established and, thus, closed and not permeable to changes, where the world of politics is clearly delimitated. While to the later, a different attitude towards the relationship between the social and the political seems to assure a singular perspective of open process to be considered, traduced in an expansive and contradictory conception of politics, in others words, of social and political intersection.
