I want people around the world to hear me. To all those who would do us harm, no act of terror will go unpunished. It will not dim the light of the values that we proudly present to the rest of the world. No act of violence shakes the resolve of the United States of America.

I favor legalizing same-sex marriages, and would fight efforts to prohibit such marriages.

America is an unlikely place - a country built on defiance of the odds; on a belief in the impossible. And I remind you of this because as you set out to live your own stories of success and achievement, it's now your turn to help keep it this way.

I'm never surprised by controversies that are whipped up in Washington.

We should be more modest in our belief that we can impose democracy on a country through military force.

We are on alert 24/7. And everything that you report will be investigated. We do it in private. We do it covertly. This could be a problem, it could simply be your neighbor having a bad day. But better be safe than sorry.

We can't, you know, use our military to make sure the planet doesn't get warmer. And so that kind of leadership, of being able to bring people together, to apply practical commonsense solutions based on facts, based on science, based on what works you know, that's been the approach I have taken consistently as a public servant. That's the kind of style that I think we need in the presidency right now.
