I very much admire Sheryl Sandberg for what she has done. I really do. But Sandberg's narrative also implies: "Well, it's your fault if you couldn't make it." There is a certain injustice in that.

Do not vote for Hillary [Clinton] because she is a woman. Ask yourself, who has done more for women so far and who will do more for women in the future - and then make your choice.

When we talk about gender pay gaps in the United States, and if you look at women without children, they earn 96 cents for every dollar that a man is earning, while for mothers it is about 76 cents. That's nearly 25 percent less. For single mothers, the situation is even worse. One third of them are living in poverty or just on the edge of poverty. This is an unacceptable situation.

What I'm suggesting is we are going to look back, and we're going to see what happened in Syria, and we're going to see the larger destabilization of the Middle East, the rise of extremism, and we're going to wonder... Why didn't we at least try to force a political solution - at an acceptable cost to us, because no one is saying we should send in ground troops - and if we did it would be worse than doing nothing... If we do not act, we are going to look back and wonder why we didn't.

I think an awful lot of the reasons people put forward for not liking Hillary Clinton play into deep-seated, negative female stereotypes: ambition, secrecy, calculating. I mean, that is Lady Macbeth, a kind of cold woman. I don't think that's Hillary. And I don't think people would judge a man in the same way.

Motherhood is a greater predictor of wage inequality than gender is. It's enormous.
