pretty sure Marcy held his own court as well as had his own soldiers/political cogs under him. From what I understand he was closely aligned with Murray Humpheys and the non-Italian crew. I read an article about when Gus Alex inherited the crew from Humphreys that he was heard complaining to one of the bosses about needing more help with the political fixing and that Marcy had recently offered to give him more backing now that he was the guy in charge of the non-Italian crew.
