This is inspiring. Hopefully, we can look forward to the day when civil rights aren't a matter of geography and campaign strategies:
Massachusetts, the first state in the nation to legalize gay marriage, has become the first state to challenge the constitutionality of a federal law that defines marriage as the union of a man and a woman, saying Congress intruded into a matter that should be left to individual states.
"In enacting DOMA (the Defense of Marriage Act), Congress overstepped its authority, undermined states' efforts to recognize marriages between same-sex couples, and codified an animus towards gay and lesbian people," the state said in a lawsuit filed today in US District Court in Massachusetts.
The lawsuit said that more than 16,000 same-sex couples have married in Massachusetts since the state Supreme Judicial Court ruled that gay marriage was legal in 2004 "and the security and stability of families has been strengthened in important ways throughout the state."
[...] The lawsuit argues that DOMA, which was enacted in 1996, precludes same-sex spouses from a wide range of protections, including federal income tax credits, employment and retirement benefits, health insurance coverage, and Social Security payments.
