A very interesting column from Carlos Loret de Mola:
Yes, everyone - PRI, PAN, PRD - is engaging in electoral fraud at some point. Yet according to FEPADE, the unit of the Mexican attorney general's office charged with investigating criminal electoral fraud, there is a clear pattern across Mexico's 32 states over the past years: Since its 1994 creation (as part of electoral institution reform), FEPADE has detected 10,227 fraudulent acts. 50 percent of these acts were committed by the PRI, 30 by the PAN, and 20 by the PRD.
What would be even more interesting than the raw percentages would be to divide the # of frauds over the units governed, but that will have to wait.
