Alejandro Encinas Rodríguez is co-founder of the PRD, and a very important person within the party. Over the past years he's threatened to leave the party a few times, all with regards to the internal dispute within the party over its resistance to Andrés Manuel López Obrador's attempt to make the PRD a completely servile party at his full service, its only purpose to exist being to bring AMLO to the Mexican presidency. Encinas was a very moderate center-left politician, who did a pretty good job holding a few different secretaries in Mexico City, and twice was interim mayor when AMLO was first impeached and when he then stepped down to pursue the presidency. But since then, Encinas has lost very much credibility as he appeared increasingly subordinated to whatever commands AMLO issued to him.
Now, with AMLO actively recruiting PRD members to join his new personal party Morena, Encinas is again in the spotlight as a possible defector from the PRD. Ex-party president Jesús Ortega, who won leadership of the party in 2008 against the AMLO-backed Encinas, called Encinas out recently: Either you go with Morena, or you stay in the PRD, but make up your mind.
Encinas' response is truly embarrassing: He will wait making he decision, and base it on whether Morena really manages to convert itself into a party (officially register with the federal electoral institute, that is). In other words, Encinas is taking no chances - he will enjoy the fat privileges of being a senator for the PRD, but is not loyal to the party and might leave it - but only if he is assured he has a new party ready for him. Say whatever you want about Martí Batres, a hard-left authoritarian unreconstructed stalinist who recently ditched the PRD, but did so in order to build AMLO's new Morena - as opposed to merely waiting for the new party to be ready - the table set, and then show up - like Encinas. This is nothing less than political cowardice.
