The alternation to democracy in Mexico had at the federal level its first fruit in 2000, to this one, preceded to him alternations in state and municipal executives, particularly in the entities of Baja California, Guanajuato and Chihuahua. However, beyond noting the political alternation as a practice that has consolidated in the country, it is necessary to ask how democratic political culture at the subnational level has changed. In this sense, this paper analyzes first the transition processes, the political culture and the quality of democracy present in the state of Chihuahua, Mexico. Based on the above, analyze the changes that have occurred in the quality of democracy at the subnational level for the state of Chihuahua, in the period 2010-2016, under a perspective compared to the state of Coahuila that has not experienced political alternation. The working hypothesis is that political alternation at the subnational level has very little impact on democratic political culture and therefore on the quality of democracy. The methodology consists of the comparative analysis of the data generated by the Research Network on the Quality of Democracy in Mexico and the Index of Democratic Development of Mexico developed by the Konrad Adenauer Stiftung Foundation, Coparmex and Polilat.
