The amicus brief signed by more than 100 Republicans urging the Supreme Court to overturn Proposition 8 got a lot of attention last week. As well it should. The prominent GOP signatories represent the enlightened wing of a party that has grown increasingly exclusive when inclusion is key to its survival as a national party. But acclimation for that brief obscured the important amicus brief filed by the NAACP Legal Defense Fund (LDF) in Windsor v. the United States (a.k.a. the Defense of Marriage Act, or DOMA, case). The 73-year-old civil rights organization was founded to battle racial discrimination in the courts. No surprise, then, that the LDF was at the Supreme Court last week fighting for the Voting Rights Act. But it also had no problem arguing that the struggle for marriage equality for same-sex couples is in line with the battle against the “separate but equal” doctrine that blocked blacks from pursuing the American dream.
