Ken Griffin, the Chicago billionaire who runs hedge fund giant Citadel and owns the enormous market-making firm Citadel Securities, says he’s "all-in" to back a candidate to try and defeat fellow billionaire and Democratic Gov. J.B. Pritzker of Illinois. "I’m going to make sure that if he runs again, that I am all-in to support the candidate who will beat him," Griffin said Wednesday during comments he made at the DealBook Online Summit hosted by The New York Times. "He doesn’t deserve to be the governor of our state."
