Barack Obama: “When I'm debating John McCain, he won't be able to say, 'Well, you supported the war, too,' because I didn't.”

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

If I had a blame pie for why politics is so polarised and why we're seeing a rise of populism in many places, it's because of that information that is going into our brains every day.

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”.

I think when we act on that basis, it doesn't always work out, but over time things do get better.
