Nearly half of all Americans live in a state or municipality that recognizes same-sex couples' relationships.

Writer Timothy Kincaid said the antigay National Organization for Marriage "can proclaim 'victory' when they have an election in California or Maine, but this ball is rolling and the momentum is in the direction of recognition."
