Other possible candidates included Giuseppe Civati, PD, and Valdo Spini, ex-PSI.
The PSI chose not to field a candidate and supported Bersani instead.

The left-wing party Italy of Values (IdV), former coalition partner with the PD in the past general election, was excluded from the coalition mainly because of the attacks made by the party leader Antonio Di Pietro against the President of the Italian Republic Giorgio Napolitano about his strong support of the Monti Cabinet and his alleged implication in the State-Mafia negotiation of 1992-93.
Nevertheless, the party unofficially backed Bersani in the contest.
