In the late Díaz period, there were efforts to anticipate the succession in 1910. Arguments were made that the nation should return to having a vice president. This interested both the anti-Díaz partisans and some Díaz collaborators, for the latter hoped to get in position to succeed the old man. Díaz never lost his grasp of politics, however.

Madero was hoping to be that candidate but Díaz never took him seriously. In 1910, Madero had decided to oppose Díaz for the presidency.
