Nope, Colorado does not currently allow such adoptions, and has not allowed them at any time during this little girl's life. Apparently courts in one county (Boulder -- not the county where Clark and McLeod reside) have allowed gay partners to be listed as a parent on a birth certificate, when the other partner has actually given birth to the child. But the practice is not recognized under state law, and there are ongoing efforts to explicitly prohibit it. No adoption has ever been allowed by two gay parents of a biologically unrelated child.

Since 1999, same-sex parents have been receiving "special" treatment.
Move along. Don't you have some placards to paint?
