TRENTON — A state Senate vote on legalizing same-sex marriage in New Jersey is expected to be delayed, its two prime sponsors said today.

Sens. Ray Lesniak (D-Union) and Loretta Weinberg (D-Bergen) said the bill — which was up for passage on Thursday — instead will likely be introduced in the Assembly Judiciary Committee in preparation for a vote by the lower house.

While even proponents conceded this week that passage was in doubt, Lesniak and Weinberg said they were not postponing the debate because they lacked the 21 votes to succeed in the Senate. They said they want Assembly members to engage in the public dialogue and hear the testimony from both sides that senators already have been exposed to.
