I've had a chance to meet some of my civil rights heroes and, more recently, members of the young generation around [Barack] Obama, people in their teens and twenties who were determined to make history and who were too idealistic to think that what they were trying to do might be impossible. They proved that visionary pragmatism can win over the majority. That comes from a particular place in your heart that generation Y is offering America. They just can't afford to be naive now, in terms of the ferocity of the opposition.
