Barack Obama: “Americans who work hard their entire lives have earned the right to retire with dignity and security.”

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

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.

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.
