As the U.S. Supreme Court heard oral arguments Wednesday over the constitutionality of the Defense of Marriage Act, supporters and opponents of the law took to the Web to make their own case.
Enacted in 1996 under a Republican Congress and Democratic President Bill Clinton, the Defense of Marriage Act, or DOMA, defined marriage for federal purposes as a union between a man and a woman.
The law also allowed states to deny legal recognition to same-sex marriages performed outside their borders and barred the federal government from recognizing same-sex marriages licensed by states.
During Wednesday's arguments, the court's four liberal justices, plus Justice Anthony M. Kennedy, expressed skepticism about the law's legality.
Among same-sex marriage supporters, hopes have been riding high for an overturn of the law, as well as a rejection of Proposition 8 in California, in which voters banned same-sex marriage. (The court heard arguments on Proposition 8 on Tuesday.)
