Governor John Lynch today signed legislation making New Hampshire the sixth state (and the fifth in New England) to allow gay marriage.
If gay marriage—or, the right of a person and another person to marry—can pass New Hampshire and Iowa, I think it's officially "mainstream." New Hampshire ("Live Free or Die") is the most Republican state in New England, and John Lynch is a Republican governor; so this isn't a party issue any more. Rhode Island politics may not permit the state to weigh in for some time (I've got emails out to some GOP friends from East Greenwich for clarification), which I kind of expected.
But now, I would hope that Illinois, Minnesota, Wisconsin, even Maryland, and other states with long progressive histories start getting marriage-equality acts through. Since it's a matter of when, not if, I would like to see my home state on the van.
