Therefore, in the specific case of Mexico, a fundamental question arises: do those mistakes affect or not, in a significant way, the results of the different candidates, especially when there is narrowness in the numbers? To answer this question, the current work analyzes in detail those cases where electoral packages were open and the votes were recounted during the federal elections of 2006 and 2009, since those exercises allow us to know, with sufficient precision, the magnitude of the mistakes done by the functionaries of the polling booths and their probable electoral impact.
