The White House is a poignant place. I spent more years working there than any President but Franklin D. Roosevelt. And it seems to me that for those who live and work there, if they are completely honest with themselves, with rare exception the most vivid memories are not of victory but of crisis and defeat — and, for a fortunate few, of one or two occasions of historical importance. This is why character counts for so much in a President. In the White House, the elation of victory is fleeting and the burden of responsibility is enduring.
