Barack Obama: “We can't engage in a lot of the public speculation and discussion.”

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”.

Use that hope to make a difference. Get involved.

And I will fight for that, even if I don’t always think it’s going to win.
