When I first started working in politics, as a junior aide on Walter Mondale's 1984 presidential campaign, it never occurred to me that I would one day work in the White House. There were plenty of women among the volunteers who stuffed envelopes and walked precincts. But there were fewer and fewer on each successive level of influence and access.

I worked for a lot of candidates, in tough campaigns that lost. Most of my candidates lost until Bill Clinton. There was always a point where you look in their eyes and they knew it was over. And there was never that point with Clinton. He never quit. He never gave up.

Women have a lot of power in private life. There are many men who would say, 'Hey, women already rule my life.' But with women, more is more. The more there are, the more the world gets used to seeing them. We change the culture. We begin to expand options and lead and manage.

Part of Obama's persona is self-reliance. He's calm; he's cool; he's self-possessed. In many ways, he has tried to define himself in opposition to Clinton's sometimes needy, often undisciplined, emotionalism.

Yes, Bill Clinton is a big flirt.

Having a sense of humor has served me more than it has hurt me - just in the sense that it has allowed me to keep my sanity.

A lot of people over time have had this kind of pattern in their relationship with Bill Clinton. You first meet him and you're overwhelmed by his talent. He's so energetic and articulate and full of ideas and he calls himself a congenital optimist and that optimism is contagious.
