I think Obama just scored an own goal with a Biden assist. I don't think this plays well in battleground states.
No state can determine who loves who. If a couple of men or women or group of men and women can find a church and a minister to hold the ceremony, then what do I care? However since the entire reason behind state liscensing of marriage was to protect women and children from men who walked away from their family, and since homosexuals do not produce children by natural means, the state has no responsibility to recognize a homosexual relationship.
That being said this is just a distractor.
The main front is jobs and the economy. Obama and the Democrats can not defend themselves and have to keep distractions like this to have any chance. If they are forced to talk about the economy, they are done and by now they know it.
