Brad Abelow was a New York resident less than three years ago when Jon Corzine asked him to become the State Treasurer. Now he’s the most powerful person in New Jersey politics. The transformation from Wall Street millionaire to state government bureaucrat hasn’t been easy: a budget crisis six months into the new administration shut down state government. But a year later, and again this week, Abelow got much of the credit for a budget accord. Politically, he’s not especially savvy. But people respect his brains, negotiating skills, fairness – and perhaps most importantly, his unconditional loyalty to Corizne.
