Now - if I was a believer in what many Republican talking heads point out, this would appear suspiciously as one of the methods of the Saul Alinsky (http://en.wikipedia.org/wiki/Saul_Alinsky) plan to distract with so many issues that no one can focus on one to fight. It seems that Obama has decided to flood more issues out. I can only see this one going badly for him - it will possibly serve to energize the 35% that truly support him. Unfortunately for him, when this issue is brought up for a vote in the various States on referendums most times the folks vote for Man-Woman marriage only overwhelmingly - even though the legislatures and the courts work against their wishes. This will serve to throw another large negative issue out there that the public will not support.

The Obama administration distanced itself Monday from legal arguments it had made earlier this summer, taking pains to remove and renounce language that had outraged advocates in the gay community in a case that centers on the constitutionality of a same-sex marriage law.

It almost seems like they are trying to provoke a backlash.
I am all for the States determining their own wishes in this issue. The reason DOMA was passed was to deal with issues regarding the Full Faith and Credit clause of the Constitution. Bill Clinton signed the Bill into law.
Full Faith and Credit
