Historically, Mexican Presidential elections come along with allegations of results manipulation, alteration of ballots and vote-buying. Using GIS an analysis of the Mexican Presidential elections results was performed. This analysis was dividend in two steps. The first step was the visualization of the voters' preference in the country almost on real-time. Using the official results, published by the Federal Electoral Institute, maps from all regions in the country were generated every 30 minutes. These maps show voter's preference and they were created using ArcMap and python scripting. In the second step, a statistical analysis was performed to identify irregularities in the percentage of assistance and the percentages of votes for each candidate. The obtained results show important anomalies in several regions of the country, especially in the poorest districts and from the winner candidate.
