Barack Obama: “The best vice president America's ever had, Mr. Joe Biden's.”

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.

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.

It is a decision about how do we face and embrace this finite amount of time we have on the planet.
