This paper analyzes how 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 electoral change and how it has translated into the party system after this election. The paper compares the results of the presidential and legislative elections between 1994-2018. 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 large part of the country, the re-concentration of power in one party, the reduction of partisan fragmentation and the changes in the nationalization of the vote of the leading forces) and the dynamics of electoral competition (the emergence of the first unified party government since 1994, the carryover effect of the presidential election in the legislative election results).

Palabras llave : elections; political parties; party system; structure of electoral competition; dynamic of competition.
