They followed suit of the House. The versions are slightly different, the Senate version adding an explicit protection for religions to marry whomever they choose, so this bill has to go through conference committee -- but it should now have no problem in passing. Now the only question is if Governor Lynch (D) will pass it. For shame -- and bigotry -- if he doesn't.
Maine's not far behind, either. MassEquality's once-ambitious push to get marriage equality across New England by 2012 is suddenly looking rather pedestrian. All of this means Rhode Island will be the last to play catchup in NE, with their rabidly anti-gay governor. Looks like that Gov just needs to go. He'll be facing competition in this year's election -- so we'll see what happens.
