In this photo taken on Wednesday, March 6, 2013, Cardinal Marc Ouellet, top center, prays next to Cardinal Angelo Bagnasco during a vespers celebration in St. Peter's Basilica at the Vatican. The Vatican insists that the cardinals participating in the upcoming conclave will vote their conscience, each influenced only by silent prayers and reflection. Everybody knows, however, that power plays, vested interests and Machiavellian maneuvering are all part of the game, and that the horse-trading is already under way. Can the fractious Italians rally behind a single candidate? Can the Americans live up to their surprise billing as a power broker? And will all 115 cardinals from around the world be able to reach a meeting of minds on whether the church needs a people-friendly pope or a hard-edged manager able to tame Vatican bureaucrats? This time there are no star cardinals and no big favorites, making the election wide open and allowing the possibility of a compromise candidate should there be deadlock.
