Americans elected Barack Obama to a second term Tuesday, with the president capturing or on the verge of winning all of the key states that had been at the center of his hard-fought campaign against Republican Mitt Romney.
"Whether I earned your vote or not, I have listened to you," Obama said early Wednesday at a speech before thousands of supporters in Chicago. "I have learned from you. And you've made me a better president.

After a campaign that has cost some $6 billion, the two candidates are in the same place they started: with President Obama a smidgen ahead of challenger Mitt Romney, so close that differences are in most cases statistically insignificant.
