The permanence of a political party in the power in Puebla for over eighteen years, characterized as hegemonic party, influenced the configuration of a set of strategies of this political organization, which made possible the molding of a political culture with broad sectors that, since 30’s, favoured with their vote to the PRI. In the local elections of 2010 the citizenship opted for an electoral alliance (left-right) represented by its main opponent (PAN), which amounted to the Executive Power of the state supported by the speech of democratic quality. In that way, To what extent and in what way did the PRI achieve the configuration of a political culture characterized by a citizenry that reiterated its support from the 30’s to before 2010?; What changes can be identified in the poblana political culture and its possible relation to explain the alternation in 2010?, Has the government had an effect of alternating democratic quality in the case of Puebla?. Thus, on the understanding that the relapse into local political power generated many expectations regarding the government of alternation, this paper reveals their inconsistences in terms of the parameters that characterize the quality democracies, for which it deepens the relationship between the changes that identify in the political culture and alternation, and, on the other hand, evaluates the PAN management (concerning the last two Governments) within the framework of the dimensions of democratic quality. To identify changes in poblana political culture the methodology used was the comparison between the results of two surveys and the analysis of the changes in the conventional/unconventional participation in various periods of study.
