My fellow Americans, all of us in this grand hall and everybody watching at home, when we vote in this election, we'll be deciding what kind of country we want to live in. If you want a winner-take-all, you're-on-your-own society, you should support the Republican ticket. But if you want a country of shared opportunities and shared responsibility, a we're-all-in-this-together society, you should vote for Barack Obama and Joe Biden.
