A brief update: Tonight the Puerto Rican senate approved a measure that calls for an amendment to the Commonwealth's constitution that would ban same-sex marriages in the island. Calling it a "nefarious day for our democracy," Pedro Julio Serrano of the gay rights organization Puerto Rico Par Tod@s also expressed dismay that the proposed amendment goes even further than expected and, if successful, would also ban civil unions between same-sex couples as well as heterosexual couples.

More information tomorrow as more is known about tonight's vote.
