El poder del voto: Cambio electoral y sistemas de partidos a nivel federal en México en 2018.

This paper analyzes the way in which the Mexican electorate modified the configuration of the party system after the 2018 election. By analyzing the structure and dynamics of electoral competition, it explores different dimensions to determine the magnitude of the electoral change and its translation in the party system after this election. For this purpose, the paper compares the results of the presidential and federal deputies' election in 2018, with the results of the elections held since the early 1990s. This research offers a historical perspective of the magnitude of the changes registered during this election in both the structure of electoral competition (the massive reorientation of the vote in a large part of the country, the re-concentration of power in a party, the reduction of partisan fragmentation and the changes in the nationalization of the vote of the main forces) and the dynamics of electoral competition (the emergence of the first government of the unified party from 1994, the effect of dragging the presidential election on legislative results).
