You are The One and only . . .

CNN has an interview in which Hilary Rodham Clinton states that she will not serve a second term as Secretary of State. As to whether she is positioning herself for another run at the White House, she said no:

Because I have the best job I could ever have. This is a moment in history where it is almost hard to catch your breath. There are both the tragedies and disasters that we have seen from Haiti to Japan and there are the extraordinary opportunities and challenges that we see right here in Egypt and in the rest of the region. So I want to be part of helping to represent the United States at this critical moment in time, to do everything I can in support of the president and our government and the people of our country to stand for our values and our ideals, to stand up for our security, which has to remain first and foremost in my mind and to advance America's interests. And there isn't anything that I can imagine doing after this that would be as demanding, as challenging or rewarding.

That would be a "yes", then.
