The appointment of Bob Menendez to the United States Senate would trigger a series of musical chairs in Hudson County. Albio Sires is the most likely candidate to replace Menendez in Congress, which would create two more vacancies: the 33rd district State Assembly seat, and Sires’ post as Mayor of West New York. If Sal Vega moves up to Mayor and/or Assemblyman, that would mean additional vacancies on the Hudson County Board of Freeholders and on the West New York Board of Commissioners. If Sires goes to Congress, he would become the first Assembly Speaker to win a House seat since Joseph LeFante moved up in 1976. Thomas Kean lost a congressional primary in 1974 (by 86 votes to Millicent Fenwick) and Peter Moraites was defeated by Henry Helstoski in 1968 — prior to his conviction on corruption charges.
