Barack Obama: “So I propose a toast to all of you.”

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.

Listen, hypocrisy is progress.

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

That's what I hope every visitor to this center takes away from their experience.
