Not that it really matters, in Rudy Giuliani’s case, he used Federal RICO laws to put the mafia leaders in jail, this case is using state RICO laws, even though the article said the state laws are modeled after the Federal Laws, I’m sure it has some differences, the article also mentioned this particular prosecutor has successfully used state RICO laws before.
Yes, if Trump were to win the election, he couldn't pardon himself from the state charges, only federal charges.
