Barack Obama: “We must change. We must change.”

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.

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

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