ESPINOZA TOLEDO, Ricardo  y  NAVARRETE VELA, Juan Pablo. MORENA in the configuration of the party system in Mexico. Estud. polít. (Méx.) [online]. 2016, n.37, pp.81-109. ISSN 0185-1616.

In the present article we observe that the system of parties in Mexico has meant the establishment of three predominant political offerings: PRI, PAN and PRD, characteristic of moderate pluralism. However, this three-party dominance has limited the growth of small parties and the emergence of a fourth competitive political force. Moderate pluralism has not encouraged the electoral development of new parties, something which is also reflected in the integration of the Congress. The emergence of MORENA, political party, came to change this logic, for their ability to become a competitive match, at the height of the other three, taking advantage of the leadership of Andrés Manuel López Obrador.
