New Jersey state Senator Raymond Lesniak on Thursday said a proposed gay marriage bill could have sufficient support to override a veto from Governor Chris Christie.

Lesniak told The Wall Street Journal that he estimates there are between 24 and 27 votes in the Senate in favor of making New Jersey the seventh state to legalize gay marriage. Twenty-seven votes are needed to override a governor's veto.

“I'm wishing and hoping,” Lesniak told the paper.

Among senators in favor of the measure, 23 are Democrats and 4 are Republicans, said Lesniak, a Democrat and co-sponsor of the legislation.

Democratic Assembly Speaker Sheila Oliver has said there is sufficient support for passage of the bill in the Assembly, and that she would work toward the 54 votes needed to override a governor's veto.

The Senate Judiciary Committee will begin debate on the bill on Tuesday.

New Jersey currently recognizes gay and lesbian couples with civil unions, but proponents of marriage equality say such unions are flawed.
