I believe, in the words of Dr. Martin Luther King Jr., that there is such a thing as being too late, and when it comes to climate change, that hour is almost upon us.

I would put our legislative and foreign policy accomplishments in our first two years against any president - with the possible exceptions of Johnson, FDR, and Lincoln - just in terms of what we've gotten done in modern history. But, you know, but when it comes to the economy, we've got a lot more work to do. And we're gonna keep on at it.

What I want to try to do is unify the two wings of the Democratic Party. What's considered the more progressive wing of the Democratic Party - the more centrist wing of the party. I think we can craft an approach that is more American, pro-worker, pro-business, pro-growth.

In Iraq and Syria, American leadership - including our military power - is stopping ISIL's advance, instead of getting dragged into another ground war in the Middle East, we are leading a broad coalition, including Arab nations, to degrade and ultimately destroy this terrorist group.

The greatest danger of all is to allow new walls to divide us from one another

When times get tough, we don't give up. We get up.

Hunger, disease and poverty can lead to global instability and leave a vacuum for extremism to fill. So instead of just managing poverty, we must offer nations and people a pathway out of poverty. And as president I've made development a pillar of our foreign policy, alongside diplomacy and defense.
