Barack Obama is a remarkable man who ran a remarkable campaign. But he is also the product of a historical shift, the most striking aspect of which is the growing power and influence of many millions who, until a moment ago, were without either. No one understands this better than Obama himself. On the occasion of his election to the American presidency, he told the American people that change "cannot happen if we go back to the way things were. It cannot happen without you."
