Study after study confirms that even when you control for variables like profession, education, hours worked, age, marital status, and children, men still are compensated substantially more - even in professions, like nursing, dominated by women. No wonder there's a gender gap.

Palin was a political Hail Mary, a long bomb in the closing minutes of a game that John McCain and Co. were certain to lose. They didn't care if she had the policy or political or emotional capacity to serve as vice president, let alone president. They were willing to drive the country off a cliff, if that's what it took to win.

There are people in the public sector with a range of experiences that have no equivalent in business, but are essential to governing, like keeping a kid in school or helping someone get and hold a job. The value of those skills can't easily be measured against a bottom line.

After I left the White House, I kept a foothold in the business of American politics as a talk-show host, analyst, commentator, speechmaker, and occasional writer. I was no longer a practitioner, but I was still a partisan, a Democrat, a blue-stater through and through.

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.

The fight is always the same within the Democratic Party, isn't it? The more things change, the more they stay the same.

Washington is still very much a male-oriented culture. Being from Los Angeles, I think it is less so there - there is less attachment to tradition, perhaps, there is more flexibility, more acceptance of change generally. That is partly because of Hollywood.

When I joined Bill Clinton's start-up presidential campaign in 1991, I was confident that women would play an ever more important role, but I never gave a minute's thought to what would happen if we won. When we did - and I became the first woman to serve as White House press secretary - it changed my life. But it didn't change the world.

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.

Obama has made America cool again - and more than that, he's made his own brand arguably the most powerful the world has ever known.
