What are the political and legal implications of the Obama administration's decision not to defend the Defense of Marriage Act?

Baker Institute fellow in law and urban economics Dan Rodriguez blogs on this question, as well as the broader role of the courts. He writes that the Obama administration's decision "may well forecast the future intention of Obama to support, fully and fulsomely, same-sex marriage. And, perhaps equally significantly, it may give political cover to federal, state and local officials -- not excluding judges -- whose ambivalence about same-sex marriage is borne more of strategic political calculations, rather than personal commitments or interpretations of the state and federal constitutions."
