Peggy Noonan: No one has ever really laid a glove on Obama before, not in this campaign and maybe not in his life.

Peggy Noonan writes in The Wall Street Journal:

Sarah Palin killed. And more than killed.

Much has been said about her speech, but a few points. "The difference between a hockey mom and a pitbull? Lipstick" is pure American and goes straight into Bartlett's. This is the authentic sound of the American mama, of every mother you know at school who joins the board, reads the books, heads the committee, and gets the show on the road. These women make large portions of America work.

She has the power of the normal. Hillary Clinton is grim, stentorian, was born to politics and its connivances. Nancy Pelosi, another mother of five, often seems dazed and ad hoc. But this state governor and mother of a big family is a woman in a good mood. There is something so normal about her, so "You've met this person before and you like her," that she broke through in a new way, as a character vividly herself, and vividly genuine.

Her flaws accentuated her virtues. Now and then this happens in politics, but it's rare. An example: The very averageness of her voice, the not-wonderfulness of it, highlighted her normality: most people don't have great voices.

What she did in terms of the campaign itself was important. No one has ever really laid a glove on Obama before, not in this campaign and maybe not in his life. But Palin really damaged him. She took him square on, fearlessly, by which I mean in part that she showed no awkwardness connected to race, or racial history. A small town mayor is kind of like a community organizer only you have actual responsibilities. He wrote two memoirs but never authored a major bill. They've hauled the Styrofoam pillars back to the Hollywood lot.

John McCain also made a speech. It was flat.
