Who will Cuperlo and De Micheli support in the ballot?

Pending definitive data, the big question in the race for the Pd primaries is: what will Gianni Cuperlo and Paola De Micheli do? Who will they support between Stefano Bonaccini and Elly Schlein? They are credited with third and fourth place, in a range between 5 (De Micheli) and 10 percent (Cuperlo). It is clear that their indication of vote could result in a stronger investiture for those who go to the ballot.
