The two main factions were those of d'Estouteville and Orsini, the latter of whom secured a major pre-conclave victory in managing to persuade the rest of the College to exclude the cardinals created by Paul II
in pectore, in explicit defiance of the
last will and testament of the previous pontiff. The voting tallies are known with specificity because of the notes of
Nicodemo de Pontremoli, sent to Duke of Milan
Galeazzo Maria Sforza, currently residing in the
State Archives of Milan. Notable favorites in the ensuing scrutinies are (chronologically): Calandrini, Forteguerri, and Roverella. Of the favored candidates of Sforza, della Rovere was the most electable, so Gonzaga and Borja lobbied for him behind the scenes, all the while disguising their intentions by voting for others until the morning of August 9, when along with d'Estouteville and Barbo they changed their votes to della Rovere in the
accessus, giving him a total of 13 votes. The cardinals voting for della Rovere in the scrutiny were: Monferrato, Zeno, Michiel, Agnifilo, Roverella, Forteguerri, Bessarion, Calandrini, and Orsini. Contrary to the perennial tradition, the five remaining cardinals did not change their votes to della Rovere in the
accessus to make the election "unanimous". ==Cardinal electors==
