More than 50 prominent leaders of color signed a letter to New York lawmakers in support of marriage equality Thursday, while a new poll suggested that African-American voters' opposition to same-sex marriage was solidifying but Latino voters' support may be increasing.

New Yorkers United for Marriage, the bipartisan coalition of five LGBT advocacy organizations working with Gov. Andrew Cuomo to pass the marriage equality bill within the next month, released the open letter from elected officials, union and community leaders to the state legislature on Thursday. The letter places the issue squarely within the context of the civil rights movement.
