There was no need for him to veto action by the New Jersey legislature that would have protected marriage equality. But, as Tom Moran notes in the Star Ledger:
he’s trying to limit the damage by emphasizing that he supports equal rights for gay couples under the state’s civil union law, and is prepared to strengthen it if needed.
It is good to see that even conservatives like him feel the need to underscore their commitment to equal rights. But in the end, it’s a phony attempt to have it both ways.
For a guy who acts so tough, it’s pretty weak to see him cave to the extreme right. He’s going against what he knows to be right for personal, political gain. And that’s sad.
