Barack Obama: “I always tell people don't underestimate the public humiliation of losing in politics.”

I’m going to insist that we can do better than we’re doing right now.

This race is going to be close. It could determine which party controls the Senate and whether Ohioans can count on the people in Washington to be fighting for you.

People need to “rediscover what’s the story we tell about how we’re going to live together, and see each other, and recognise each other, and disagree, and yet, still care for each other”.
