Children inspire the candidate's wife to push harder for White House goal.

The wife of presidential candidate Barack Obama says “she’s desperate for change” and “it’s now or never” to take the White House, according to Vanity Fair. As a mother of two daughters, Sasha, 6, and Malia, 9, she says, “I think about the country I want to give my children, it’s not the world we have now. All I have to do is look into the faces of my children, and I realize how much work we need to do.”
