Well, it looks to us as though it's over with. Not only did the amendment fail to win the 67 votes required for ratification; it never even came to an actual vote. Rather, the Senate rejected a motion for "cloture," which required the assent of 60 members and would have allowed a vote on the amendment itself. Of great symbolic importance, the vote to allow a vote didn't even command the support of a majority of senators. The vote was 50-48 against cloture. (The two absentee senators, Kedwards, said they would have voted "no.")
This means that supporters of same-sex marriage can claim for the first time to have prevailed in a democratic process, which will lend political legitimacy to the inevitable court decisions awarding gay couples the right to marry--already in Massachusetts, later in a few other states, and ultimately throughout the country. The question is no longer whether America will allow men to marry men and women women, but how soon, in how many states, and when the federal courts will start turning this into national policy.
