Colorado OKs Civil Unions Backers vow to push for same-sex marriage next By John Johnson, Newser Staff Posted Mar 12, 2013 9:50 PM CDT Updated Mar 12, 2013 10:05 PM CDT 18 comments Comments Rep.

Democratic Gov. John Hickenlooper will sign the measure into law in May, and activists promised to keep pushing for recognition of marriage itself. The vote comes about two weeks before the Supreme Court hears arguments in two separate cases that have the potential to determine whether the Constitution guarantees a right to same-sex marriage, notes NBC News. "We're not there yet,” says a state senator who sponsored the bill. “Civil unions are not marriage. They are something that are separate and distinct and lesser and unequal and that really is not good enough." Voters in Colorado approved a 2006 constitutional amendment that defines marriage as a union between a man and a woman.
