Shabot on the Left

His take is a pessimistic one:

The rupture [between the moderate and extreme branches of the left] turned out to be inopportune because both sides needed each other to traverse the July election, but the level of confrontation, which grew with time, ended up further lowering the probable votes in favor of the PRD. 

An AMLO with one foot in the Party of the Aztec Sun and another in the Workers Party and Convergencia intensified the division and the internal war. The spat between Amalia García and Ricardo Monreal and the negative reaction of Ortega toward using López Obrador as a figure of support for perredista candidates in Mexico City demonstrates unequivocally that the truce between both groups, for electoral reasons, didn't work and that every political fief is willing to sacrifice the other, even if if sinks the party in the election on July 5th. 

Now more than ever, in the midst of a deep economic crisis, the position of a modern left is seen as a viable alternative for Mexico. 

The problem is that the left that we have is more bound to its priísta past and the absence of a project common to its distinct factions, than to the fundamental objective of constructing a more developed and more just Mexico. As such, the Mexican left races toward collective suicide, without anyone able to stop it.
