I think that it’s fairly clear that the right wing PAN is attempting a back door privatization of Pemex, the state own oil producer, while the PRD sees any change as an theft from the Mexican people, and the PRI falls somewhere in between.
The problem is that Pemex has not been run well, and it is lacking resources as a result, so some sort of reform is necessary.
I still believe that purchasing the necessary expertise, as opposed to “risk sharing partnerships” that are a back door way of privatizing the system, are the way to go.
