A largely female audience of more than 1,100 people crammed into a conference center ballroom for the first lady's appearance. Several hundred others waited outside.
Mrs. Bush talked out the gains woman have made in Iraq and Afghanistan now that they're free of oppressive governments they once lived under.
She says women in Afghanistan had been prisoners in their own homes, but now more than 10 million people have registered to vote, 40 percent of them women.
The first lady will also stop in Iowa and Indiana later Monday.
