Yesterday, the left's governors-elect and PRD, the largest party on the left, declared they will accept Enrique Peña Nieto's victory, however grudgingly - which clearly distinguished them from AMLO. There is rarely such a thing as a coincidence in politics.In this new stage of my life, I will dedicate all my imagination and work to the cause of the transformation of Mexico. I will do this from the space that MORENA represents, and therefore separate myself from the parties of the Movimiento Progresista [the name of the 2012 coalition].This is not a rupture; I leave on the best terms. I separate myself from the the progressive parties with my deepest thanks to their leaders and activists.
