Point well taken. It still doesn't make sense to me why these politicians would only want Vito's money, as opposed to Sonny's money, but then why would half the Corleone's political muscle disappear, while half would be there for Sonny? That's what I don't understand about Tom's line.
Well, if it were just a matter of money that secured political and legal cooperation, then I am sure that Barzini, Tattaglia, Cuneo, et al had plenty of money to secure that cooperation. So, obviously, Vito's relationships had more than a financial aspect to them, right.
