The brief New Jersey residency of David Szuchman is over. When Gov. Jon Corzine named the former Eliot Spitzer aide to head the state Division of Consumer Affairs in 2007, Szuchman took some heat – from Democrats Raymond Lesniak and Nicholas Scutari — for being a New York resident and not a member of the New Jersey bar. Szuchman promised to take the bar (he did, and passed) and moved his family to Demarest. A casualty of Corzine’s own unemployment, Szuchman has gone back to New York; he is now running the cyber crime unit for the new Manhattan District Attorney, Cyrus Vance, Jr. — much bigger, higher profile job.
