Here's last week's column from Macario Schettino, noting that two decades ago, there was no polling industry to speak of in Mexico. Among other more important things, this would have severely limited the ability to write about elections with some degree of precision, which would have sucked for op-ed columnists. Or maybe the alternative: they could write about whatever they wished without any regard for objective perceptions of electoral reality, in which case it would have been a bad deal for the readers. Anyway, the current existence of so many top-flight pollsters in Mexico is another of the illustrations of how far the nation has come in two decades.
Also, today Schettino notes the unusually wide swings in opinion regarding the economic prospects for 2012.
