The Times editorial on why the endorsement matters:
With those 10 words, Mr. Obama finally stopped temporizing and “evolving” his position on same-sex marriage and took the moral high ground on what may be the great civil rights struggle of our time. His words will not end the bitter fight over marriage rights, which we fear will continue for years to come. But they were of great symbolic value, and perhaps more. As Mayor Michael Bloomberg noted, no expansion of rights embraced by a president has failed to become the law of the land.(Image: A poster, seen at Obama campaign headquarters, via SFist)
