Giuliani's top Nevada contributor is Frank Fertitta III. Yes, some of his relatives ran a crime family in the past. His Dad had mob ties (though he wasn't a boss or anything), given that he worked in Vegas before the 1970's. That doesn't mean Frank III is a mobster. Just because a man's Dad or uncles were mobsters doesn't make him one. Some people have accused him of mob ties, but as far as I know, there's no evidence. It's highly unlikely that he has any given that he's the CEO of a major public corporation, and no major public corporation is going to get involved with the mob. The risk of getting slapped with a RICO suit is simply not worth it, and being public makes it virtually impossible to hide mob involvement from the feds. Publicly traded casinos make so much money legally, why would they take the risk of getting in the mob? How could that possibly make any financial sense for them?
As to Kerik having connections with the Fertitta family, I find that highly suspect. He took kickbacks from a construction company with ties to the Gambino family, whose boss, incidentally, Giuliani put in prison when he was a prosecutor. The Fertitta and Gambino families historically have been mortal enemies, so I don't see how you can possibly draw a connection between Kerik and the Fertittas.
A little more digging and you’ll find some suspect deals and business dealings with the Gambino family.
Then you can go back to NY a read about all those that Rooty surrounded himself with that wound up in prison or forced to resign because of criminal dealings and it makes the “crime fighter” label a joke.
If Rooty were to get the nomination the Demonrats would break out a scandal a week until election day.
