LO SIGUIÓ durante una década, le pagó con creces el apoyo con el que lo impulsó a la candidatura para la jefatura de Gobierno del DF (bueno, hasta contratos irregulares le extendió a su círculo cercano). Se hizo a un lado cuando se debatió la candidatura presidencial. Pero Marcelo Ebrard inició ayer su deslinde de Andrés Manuel López Obrador con una frase impecable: la ley me obliga a respetar la decisión del tribunal federal electoral. No faltarán los fans del tabasqueño que le quieran cobrar a Marcelo lo que estimarán una afrenta. Como sea, es el principio del fin entre ambos personajes.I guess it depends on what you mean by definitive, but I don't think this marks in any way a break with the dynamic that has held Ebrard back lo these many years. (Or at the very least two years or so.) That is, Ebrard didn't break with AMLO in the past not because the time hadn't come yet, but because AMLO retains veto power over a divided left. He can call it a break now, but AMLO's power is still such that Ebrard won't enjoy the support of a united left unless AMLO decides to cede it to him, and there's no evidence that he will. To wit: Bajo Reserva and other sources have also reported that AMLO was considering forming his own party. Essentially, Ebrard would be able to take over the PRD, but he just won't be able to win the presidency with it as long as AMLO refuses to step aside.
Nothing lasts forever, and six years is a long time in politics, so it's certainly not a given that AMLO will spike Ebrard's chances in 2018. Nonetheless, knowing what we know about the principals, the scenarios in which this doesn't happen are less plausible than the ones in which it does.
