Barack Obama: “The private sector — not government — is, was, and always will be the source of America's economic success.”

Now the ball’s in your court, Iowa.

This idea that any suggestion or criticism that America was anything other than perfect is unpatriotic... is a suggestion that you hate your country.

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.

That was fantastic. I was a little tall for it.
