Perhaps most tellingly, however, was how the changes of the previous 50 years had transformed the electorate, especially the transformations brought about by the 1965 Immigration Act and the increasing recognition of the diversity of the United States. For instance, overwhelming numbers of ethnic and racial minorities voted for Obama (making up 45 percent of his total popular vote—a record), while white Americans supported Romney, 59 percent to 39 percent. Meanwhile, more than 55 percent of women voted for Obama, while only 47 percent of men did.
But the nation remains politically divided. Obama won only 50 percent of the popular vote to Romney's 48 percent, and Republicans maintained control of the House, while Democrats kept the Senate. But as Obama said in his victory speech, “These arguments we have are a mark of our liberty. We can never forget that as we speak, people in distant nations are risking their lives right now just for a chance to argue about the issues that matter, the chance to cast their ballots like we did today.”
