CSIS' second strange election analysis of Guerrero election

Here's a short analysis of this weekend's gubernatorial election in Guerrero by Center for Strategic and International Studies (CSIS), this time by Duncan Wood.

First, a minor point, but a point nonetheless:  Zeferino Torreblanca is absolutely not "the current PRI governor" of Guerrero; while he likely supported the PRI candidate, as he had run afoul of the party that postulated him, the PRD, he is not a priista.

Second, and what I most take issue with here, is the statement that:  "This second, informal alliance [with PAN], is what turned the tide in favor of the PRD candidate, Angel Aguirre Rivero, and lends credence to the idea that only the PAN and PRD working together have a realistic chance of defeating the PRI across large swathes of the country."

This is a bit rich: The PAN candidate was registering around 4-7 percent in the polls; Aguirre in the end won by more than 13 points. I don't think Parra's declination in favor of Aguirre, while it certainly helped, is what "turned the tide."

These may not be the biggest quarrels, yet as CSIS claims to present "Strategic analyses and bipartisan policy solutions," I think they should be held to quite high standards. I don't think CSIS would disagree.
