New Jersey state Senate President Stephen Sweeney (D) pledged that the state’s new marriage equality bill will go to key legislative committees “immediately’’ and said he anticipated that the Senate will vote on the measure by March. “It’s gonna be a fight. We expect it to be a fight,’’ Sweeney said. “The governor’s a decent person and I think we can work on educating him to the fact of what it means.’’ Christie supports civil unions for gay and lesbian couples, but opposes marriage equality. Sweeney also blocked a same-sex marriage bill in 2009 and has since described the decision as the “biggest mistake” of his career.
