Bensonhurst, it can't not be argued that John Gotti positioned himself to control the commission, however by the time Massino got his seat, Gotti was locked up, and the 3rd Colombo war weaken that family to where they were not effective and once again kicked off the commission. This was of course Gottis own doing. He had a strong ally in Orena, but Gotti was some of the Colombo family business and gave tactic support to Orena when it was discovered that Carmine Persico was thinking of doing a movie about his life. That was the perfect opening for John Gotti to do his double cross.
The thing is to not forget that the even though the Gambinos controlled the Colombos, Bonannos, Philadelphia, DeCavalcantes, and LoScalzo in Tampa. The Genovese family controlled Boston, Pittsburgh, Philadelphia, Buffalo, Cleveland, and Detroit. They were and are still powerful in the unions to this day.
