Maine is one step closer to becoming the fifth state in the country to allow same-sex marriage: The state Legislature has voted 89 to 57 to approve it. The bill now goes back to the state Senate, which has already passed it. If the measure is approved, it goes to Gov. John Baldacci, who once was an opponent of gay marriage but now says he’s keeping an open mind on the issue. Passage of the legislation in Maine would make Rhode Island the only state in New England that does not allow same-sex marriage.
