Barack Obama: “No one pays a higher price for our freedom than members of our Nation's military and their families.”

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

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”.

When we choose, when we make that decision, I do believe – and there is evidence for this – that the world gets incrementally better, and that is a worthy goal and it’s worth fighting for.
