Obama is now clearly for same sex marriage yet the DNC won't push to repeal DOMA...is this the tail wagging the dog?

President Obama declared his personal support for same-sex marriage yesterday, but the White House chose not to push for the repeal of the Defense of Marriage Act today.

“Well, party platform issues are for the party to decide,” White House Press Secretary Jay Carney said when asked if Obama would call for the repeal of DOMA and endorsement of pro-gay marriage language in the party platform. “That process is underway, and I refer you to the DNC on the question about the platform.”

Is this two steps forward and two steps back? Who is really running our Government here?
