"In 2006, when then-Sen. Obama voted against the Federal Marriage Amendment, he said, 'Decisions about marriage should be left to the states.' He was right then; and as I have come to realize, he is right now in concluding that DOMA has to go. If one truly believes in federalism and the primacy of state government over the federal, DOMA is simply incompatible with those notions."
