Michelle Obama hit her stride tonight.

She did exactly what she needed to do at the Democratic Convention.

I was astounded watching her, and captivated as the cameras panned over the faces of the delegates.  I was particularly struck by the diversity in the room.  All the women, all the people of color, all Democrats.

This is the party of the people.

Some excerpts from Michelle’s speech:

I come here tonight as a sister, blessed with a brother who is my mentor, my protector and my lifelong friend.

I come here as a wife who loves my husband and believes he will be an extraordinary president.

I come here as a Mom whose girls are the heart of my heart and the center of my world – they’re the first thing I think about when I wake up in the morning, and the last thing I think about when I go to bed at night. Their future – and all our children’s future – is my stake in this election.

And I come here as a daughter – raised on the South Side of Chicago by a father who was a blue collar city worker, and a mother who stayed at home with my brother and me. My mother’s love has always been a sustaining force for our family, and one of my greatest joys is seeing her integrity, her compassion, and her intelligence reflected in my own daughters.

Reflecting on her place in history, and ours:

I stand here today at the crosscurrents of that history – knowing that my piece of the American Dream is a blessing hard won by those who came before me. All of them driven by the same conviction that drove my dad to get up an hour early each day to painstakingly dress himself for work. The same conviction that drives the men and women I’ve met all across this country:

People who work the day shift, kiss their kids goodnight, and head out for the night shift – without disappointment, without regret – that goodnight kiss a reminder of everything they’re working for.

The military families who say grace each night with an empty seat at the table. The servicemen and women who love this country so much, they leave those they love most to defend it.

The young people across America serving our communities – teaching children, cleaning up neighborhoods, caring for the least among us each and every day.

People like Hillary Clinton, who put those 18 million cracks in the glass ceiling, so that our daughters – and sons – can dream a little bigger and aim a little higher.

People like Joe Biden, who’s never forgotten where he came from, and never stopped fighting for folks who work long hours and face long odds and need someone on their side again.

All of us driven by a simple belief that the world as it is just won’t do – that we have an obligation to fight for the world as it should be.

That is the thread that connects our hearts. That is the thread that runs through my journey and Barack’s journey and so many other improbable journeys that have brought us here tonight, where the current of history meets this new tide of hope.

That is why I love this country.

And the specifics:

That’s why he’s running – to end the war in Iraq responsibly, to build an economy that lifts every family, to make health care available for every American, and to make sure every child in this nation gets a world class education all the way from preschool to college. That’s what Barack Obama will do as President of the United States of America.

He’ll achieve these goals the same way he always has – by bringing us together and reminding us how much we share and how alike we really are. You see, Barack doesn’t care where you’re from, or what your background is, or what party – if any – you belong to. That’s not how he sees the world. He knows that thread that connects us – our belief in America’s promise, our commitment to our children’s future – is strong enough to hold us together as one nation even when we disagree.

We’ll be talking about Michelle tomorrow, and for many days to come.

Right now, John McCain is talking about Michelle, seated at one of his many kitchen tables, trying to imagine how he can possibly pass.

Michelle, thank you.
