In late 2006, Barack Obama held a meeting with his wife, Michelle, and his advisers to weigh whether he should run for president.
"And Michelle Obama, in front of everybody, asks her husband a very dramatic question," says New York Times Washington correspondent Jodi Kantor. "She says, 'What do you think you can bring to this that the other candidates can't?' "
Her husband paused for a second, and then responded, "I really think if I became president, it would inspire people all over the world to think of new possibilities."
