an analysis of ex-president néstor kirchner's speeches is suggested to investigate the convenience of using grammatical pronouns and tools provided by the theory of polyphony in the construction of political discourse. the latter does not directly create meanings in a particular society, but its analysis allows people to understand the hegemonic pretensions of those who pronounce it (what they say they do when they speak). politicians manage some specific strategies in which political representation and rhetorical formulas accomplish a fundamental role. the case studied in this work permits to comprehend some aspects proposed by the political power to define a primary imaginary frontier, peculiar to the peronist discourse, and characterized by the opposition 'we' / 'the others'. apparently, the appropriation of particular grammatical pronouns and the insertion of certain points of view (polyphonic voices) collaborate to revitalize the peronist scene.
