It was the labor movement that helped secure so much of what we take for granted today. The 40-hour work week, the minimum wage, family leave, health insurance, Social Security, Medicare, retirement plans. The cornerstones of the middle-class security all bear the union label.

I have been a strong proponent of pay-as-you-go. Every dollar that I've proposed, I've proposed an additional cut so that it matches.

For Democrats who are feeling completely discouraged, I've been trying to remind them, everybody remembers my Boston speech in 2004. They may not remember me showing up here in 2005 when John Kerry had lost a close election, Tom Daschle, the leader of the Senate, had been beaten in an upset. Ken Salazar and I were the only two Democrats that won nationally. Republicans controlled the Senate and the House, and two years later, Democrats were winning back Congress, and four years later I was President of the United States.

Let it be said to our children's children that when we were tested we refused to let this journey end, that we didn't turn our back nor did we falter; and with eyes fixed on the horizon and God's grace upon us, we carried forth that great gift of freedom and delivered it safely to future generations.

[Michelle Obama] used to say to our friends, "Barack's exactly the kind of guy I want to be president. I just wish he didn't want to do it when I was married to him."

We, the people, still believe that our obligations as Americans are not just to ourselves, but to all posterity. We will respond to the threat of climate change, knowing that the failure to do so would betray our children and future generations. Some may still deny the overwhelming judgment of science, but none can avoid the devastating impact of raging fires and crippling drought and more powerful storms.

I believe that for all our imperfections, we are full of decency and goodness, and that the forces that divide us are not as strong as those that unite us.
