In his book "El mito del fraude electoral en México" ("The myth of electoral fraud in Mexico"), Fernando Pliego Carrasco made a study of the beneficiaries of several government social programs, sorted by the marginalization index of the electoral district in which they lived. The programs he considered were the "Desarrollo Local Microrregiones" program ("Microregion Local Development"), and the "Desarrollo Humano Oportunidades" ("Opportunities Human Development") programs of the federal government, and to a lesser extent the program of "Empleo Temporal" ("Temporal Employment"), "Vivienda Rural" ("Rural Housing"), and "Atención a los Adultos Mayores en Zonas Rurales" ("Help for the Elderly in Rural Zones"). The first two were specifically mentioned by the Alianza por el Bien de Todos in their judicial filings. Pliego Carrasco is a Ph.D. in Social Sciences by the Colegio de Mexico, specializing in Sociology, and is a researcher at the Institute of Social Research of the Universidad Nacional Autónoma de México.
