Barack Obama: “We didn't become the greatest nation on Earth because we just stood still in the face of great challenges.”

I think when you understand the complexities of America and the contradictions of America, I don’t think it makes you love it less. I think it makes you love it more.

In forming our union, the founders fell terribly short of the Declaration's promise, leaving slavery intact, allowing states to restrict the franchise to white men who owned property.

It shows me somebody who’s not focused on the American people and the job they’re supposed to do.

Every president here today, as different as we are, has tried our best to uphold the values that John McCain and Mitt Romney believed in no less than I did.
