Gobernanza electoral y ¿voto nulo escolarizado? El efecto de la coalición parcial y de la boleta electoral en la elección federal de 2012 en México

During the 2012 diputies federal election in Mexico, the combination of two factor cause the raising of null voting at the state level: i) the changes in the structure of the electoral ballot and ii) the partial coalition between the Partido Verde Ecologista de México (PVEM) and the Partido Revolucionario Institucional (PRI). This article shows that in the states where the partial coalition does not have presence, the null votes increase, meanwhile in the states where the coalition does occurs the levels of null voting decrease. Moreover, in the states where the partial coalition does not have presence, the relationship between the null voting and the schooling is positive, contradicting to the prior research.
