And I believe the nation that invented the automobile cannot walk away from it.

Sometimes if your only approach is cutting spending at a time when the economy's contracting, then the economy will contract further.

We believed we could prepare our kids for a more competitive world. And today, our younger students have earned the highest math and reading scores on record. Our high school graduation rate has hit an all-time high. And more Americans finish college than ever before.

Let me be absolutely clear. Israel is a strong friend of Israel's. It will be a strong friend of Israel's under a McCain administration. It will be a strong friend of Israel's under an Obama administration. So that policy is not going to change.

Today, we are closer to fulfilling America's promise of economic and social justice because we stand on the shoulders of giants like Dr. King, yet our future progress will depend on how we prepare our next generation of leaders. We must fortify their ladders of opportunity by correcting social injustice, breaking the cycle of poverty in struggling communities, and reinvesting in our schools. Education can unlock a child's potential and remains our strongest weapon against injustice and inequality.

In the campaign back in 2007, 2008, people would say, "Oh, he's being naïve. He thinks that there's no red states and blue states. And wait 'til he gets here."

For we've seen how spikes in food prices can plunge millions into poverty, which, in turn, can spark riots that cost lives, and can lead to instability. And this danger will only grow if a surging global population isn't matched by surging food production. So reducing malnutrition and hunger around the world advances international peace and security - and that includes the national security of the United States.
