From the AP:

Ten House Democrats voted with nearly all Republicans in favoring of putting on May’s primary ballot a question that would make marriage the only domestic legal union recognized in this state. The bill passed 75-42 — above the 72 needed for any constitutional change — and is now headed for debate Tuesday in the Senate. A similar three-fifths majority would be needed.

Although 30 states have gay marriage bans in their constitutions, North Carolina is the only state in the Southeast without such a marriage limit there. State law already defines marriage between a man and a woman, but amendment supporters argue traditional marriage would be better protected against potential legal challenges by same-sex couples married in six other states and the District of Columbia.

Yup.  North Carolina already defines marriage as between a man and a woman, but now gay-bashers want it in the North Carolina Constitution.

Hopefully, the Senate will reject this.  And if they don't, hopefully the people of North Carolina will reject the measure.
