HERNANDEZ RODRIGUEZ, Rogelio. A Competition without Rules: The Presidential Candidacy of Roberto Madrazo. Polít. gob [online]. 2009, vol.16, n.spe2, pp.15-49. ISSN 1665-2037.

The disputed presidential elections of 2006 moved the PRI to third place of preferences. While there was a deep polarization between the parties of left and right, and errors in the PRI 's campaign, it is also possible to find another cause in the process of choosing the candidate Roberto Madrazo. This paper reconstructs the nomination process of 2005, as well as the historical and short-term conditions that made it possible, the internal confrontations and recomposition of interests of political groups in the PRI, which allowed, for the first time in the history of this party, to make its leader a presidential candidate.
