Lorenzo Córdova Vianello, one of the nine councilors of Mexico's federal electoral institute, called for political actors - candidates, public servants - to be "responsible" in their use of public opinion polls ahead of Mexico's 2012 election, and not "contaminate" the electoral enviroment.
I think that can safely be taken as a finger pointing at Felipe Calderón, who happened to display, proud as a rooster, a poll that showed PAN's candidate trailing by only a few percentage points. No other poll - none - has showed anything remotely close to these figures.
Córdova also drew attention to the "irresponsibility" of politicians pointing to dubious and made-to-fit polls, an increasing problem in Mexico. All parties should feel this criticism sting a bit.
(On another note: Lorenzo Córdova is a man to keep in mind for future higher offices. I have been reading much of his work recently, and most of it is very brilliant stuff. I don't think being an IFE councilor - as important and prestigious as that job is - will be the zenith of his career.)
