The most prominent black politician in the United States certainly seems to be for it.
were in did he says he will work, using his position-influence as president to forward gay marriage? what did he say? exactly?
Where did I say he would do that? Oh right--I didn't.
Federalizing marriage law is the right's goal. It's not clear why that should be Obama's as well now that he's expressed his personal support for gay marriage. Democrats should focus on getting rid of DOMA (which the administration has stopped defending in court), work on legalizing it at the state level wherever possible, and let Article IV handle the rest.
I have a feeling that the electoral damage Republicans inflicted in 2004 by getting gay marriage on state ballots will be visited back upon them in repeal votes in many of those states within the decade. Public opinion on the issue is shifting remarkably rapidly.
