Another vote, another win for gay rights—this time in Maryland where the House of Delegates voted to approve gay marriage. The measure passed by a thin margin—71 to 67—and now heads to the Maryland State Senate, which is expected to approve the legislation. A similar bill failed to gain enough votes in the House last year. Gov. Martin O’Malley, a strong proponent of gay marriage, lobbied for the bill this week and will approve it once it passes the upper chamber. The news comes on the heels of New Jersey Gov. Chris Christie vetoing a same-sex marriage bill in the Garden State.
