This is democracy’s day. A day of history and hope of renewal and resolve through a crucible for the ages. America has been tested anew and America has risen to the challenge. Today, we celebrate the triumph not of a candidate, but of a cause, the cause of democracy. The people, the will of the people, has been heard and the will of the people has been heeded.
We’ve learned again that democracy is precious. Democracy is fragile. At this hour, my friends, democracy has prevailed1.

I thank my predecessors of both parties for their presence2 here today. I thank them from the bottom of my heart.
