The Gay Marriage Debate This week, Massachusetts Gov. Mitt Romney begged the Senate Judiciary Committee to take up a constitutional amendment banning same-sex unions.

She believes marriage is a bright, divisive line restricting many people -- not just gays -- from an entire set of rights and privileges. Hear Polikoff and NPR's Scott Simon.
