Barack Obama: “Liberty was chosen from a flock of about 30 other contestants for the honor of being here today.”

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

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.

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

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.
