Barack Obama: “It reminds us that liberty and democracy do not come easily; we must win them, tend to them constantly, and defend them…”

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.

They're meant to remind us of who we can be, to remind us of what's possible, so we can forge ahead.

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

America is currently experiencing anger and vision but we are looking for fairness and common sense and mutual respect."
