New Jersey is a unique state nationally when it comes to this issue. That became very clear with a governor's race in which candidates on both sides opposed an amendment to the state constitution that would limit marriage to a man and a woman.

This development in New Jersey is particularly good for people who can't afford wills. This is the tiniest of baby steps compared to the one giant step of marriage.
