I just researched this for my blog Cosa Nostra News -- the Genovese Family, not the Gambinos, is now recognized as the most powerful Cosa Nostra family in the United States.

I also tried to put together briefs on who is running each of the Five New York Families and one trend leaps out: It seems triumvirates are replacing the long-standing tradition of a single-boss institution. It's like they are taking the boss, underboss and consiglieri, making them of equal rank, and creating a panel to run some of the families (about three use this kind of panel).

They may be doing this because it could help them in that it could confuse the Feds, who like those pyramid charts with all the headshots taped to the wall, stop any one man from becoming too powerful, and ease potential problems that could arise if factions are created.
