Many differences are rooted in biology and reinforced through culture, so it's important to acknowledge that. Because if you say men and women are the same and if male behaviour is the norm, and women are always expected to act like men, we will never be as good at being men as men are.

When I became White House press secretary, there were other limitations that were thrust upon me. Bill Clinton was under pressure to appoint women to visible positions. I was 31, I'd never worked in Washington. Was I ready for this large and visible job? Still he wanted the credit. So he gave me the job but diminished the job.

'Not again!' I thought to myself this morning, as news trickled out that John McCain was set to pick Alaska governor Sarah Palin as his running mate. Not again, because too often women are promoted for the wrong reasons, and then blamed when things don't go right.

President Clinton intentionally created a structure that was a little loose. And one that kept him a little in the center. He didn't want one person filtering all the information that went to him. He had always operated with a lot of information coming in and a lot of stuff going out.

Women have to be the biggest champions in the world of other women's choices.

Bill Clinton sitting on Air Force One getting his hair cut while people around the country cooled their heels and waited for him, became a metaphor for a populist president who had gotten drunk with the perks of his own power and was sort of, you know, not sensitive to what people wanted.

Every press secretary faces an enormous amount of information. Events move really fast. You're responsible for a tremendous amount of information, and again, a tremendous amount on competing agendas. Not everybody grease in the White House.
