“Today we celebrate the triumph, not of a candidate, but of a cause — the cause of democracy.
“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.
“And at this hour, my friends, democracy has prevailed.”
He added: “Today, on this January day, my whole soul is in this: Bringing America together, uniting our people, uniting our nation.

“For all those who supported our campaign, I’m humbled by the faith you placed in us. To all those who did not support us, let me say this. Hear me out as we move forward. Take a measure of me and my heart.
“If you still disagree, so be it. That’s democracy. That’s America. The right to dissent peaceably within the guardrails of our republic is perhaps this nation’s greatest strength.
“Yet hear me clearly. Disagreement must not lead to disunion. And I pledge this to you. I will be a president for all Americans. All Americans. And I promise you, I will fight as hard for those who did not support me as for those who did.”
