Later, toward the end of my presidency, The New York Times would run an article about my visits to the military hospitals. In it, a national security… - Barack Obama

To dismiss the magnitude of this progress -- to suggest, as some sometimes do, that little has changed -- that dishonors the courage and the sacrifice of those who paid the price to march in those years. Medgar Evers, James Chaney, Andrew Goodman, Michael Schwerner, Martin Luther King Jr. -- they did not die in vain. Their victory was great. But we would dishonor those heroes as well to suggest that the work of this nation is somehow complete. The arc of the moral universe may bend towards justice, but it doesn’t bend on its own. To secure the gains this country has made requires constant vigilance, not complacency. Whether by challenging those who erect new barriers to the vote, or ensuring that the scales of justice work equally for all, and the criminal justice system is not simply a pipeline from underfunded schools to overcrowded jails, it requires vigilance. And we'll suffer the occasional setback. But we will win these fights. This country has changed too much. People of goodwill, regardless of party, are too plentiful for those with ill will to change history’s currents.

My name may not be on the ballot, but our progress is on the ballot. Tolerance is on the ballot. Democracy is on the ballot. Justice is on the ballot. Good schools are on the ballot. Ending mass incarceration – that's on the ballot right now! And there is one candidate who will advance those things. And there's another candidate whose defining principle, the central theme of his candidacy is opposition to all that we've done. There's no such thing as a vote that doesn't matter. It all matters. And after we have achieved historic turnout in 2008 and 2012, especially in the African-American community, I will consider it a personal insult, an insult to my legacy, if this community lets down its guard and fails to activate itself in this election. You want to give me a good sendoff? Go vote.

What’s at stake in this debate goes far beyond a few months of headlines, or passing tensions in our foreign policy. When you cut through the noise, what’s really at stake is how we remain true to who we are in a world that is remaking itself at dizzying speed. Whether it’s the ability of individuals to communicate ideas; to access information that would have once filled every great library in every country in the world; or to forge bonds with people on other sides of the globe, technology is remaking what is possible for individuals, and for institutions, and for the international order. So while the reforms that I have announced will point us in a new direction, I am mindful that more work will be needed in the future. One thing I’m certain of: This debate will make us stronger. And I also know that in this time of change, the United States of America will have to lead. It may seem sometimes that America is being held to a different standard. And I'll admit the readiness of some to assume the worst motives by our government can be frustrating. No one expects China to have an open debate about their surveillance programs, or Russia to take privacy concerns of citizens in other places into account. But let’s remember: We are held to a different standard precisely because we have been at the forefront of defending personal privacy and human dignity.
