Barack Obama: “We will never waver from our goal of disrupting, dismantling, and ultimately defeating Al Qaida.”

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.

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

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.

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.
