Preliminary Results

The polls are showing somewhere between 38 and 40 percent of the deputy vote going to the PRI, with between 29 and 31 to the PAN. That would spell a bigger margin of victory for the PRI than most polls were forecasting, though it wouldn't be enough to snag a majority in the Chamber of Deputies. The governor's races are also leaning the PRI's way. It took Nuevo León, Querétaro, Colima, and Campeche (and none was particularly close), while San Luis Potosí and Sonora are neck and neck. 

Even factoring expectations of a PRI whitewash, it's definitely a good night for Paredes, Beltrones, and co. 

Update: I was incorrect about Querétaro, it stands at three points with the PRI in front.
