Paragraph Four of the Department of Justice Memo says it all:

After careful consideration, including a review of my recommendation, the President has concluded that given a number of factors, including a documented history of discrimination, classifications based on sexual orientation should be subject to a more heightened standard of scrutiny. The President has also concluded that Section 3 of DOMA, as applied to legally married same-sex couples, fails to meet that standard and is therefore unconstitutional. Given that conclusion, the President has instructed the Department not to defend the statute in such cases. I fully concur with the President’s determination.

This is a huge victory. FINALLY.

UPDATE: House Speaker John Boehner, in an absolute fit of political amnesia, released a statement.

While Americans want Washington to focus on creating jobs and cutting spending, the President will have to explain why he thinks now is the appropriate time to stir up a controversial issue that sharply divides the nation.

Because abortion, slavery, and lay-offs are not controversial? So be it.
