Barack Obama: “And that's why the United States will do what we must to prevent Iran from obtaining a nuclear weapon.”

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

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

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

Please join me in supporting Sherrod Brown. He’ll always fight for Ohio.
