“This is the moment we must come together to save this planet. Let us resolve that we will not leave our children a world where the oceans rise and famine spreads and terrible storms devastate our lands.”

“The success of our economy has always depended not just on the size of our gross domestic product, but on the reach of our prosperity; on the ability to extend opportunity to every willing heart - not out of charity, but because it is the surest route to our common good.”

“If there's a child on the south side of Chicago who can't read, that matters to me, even if it's not my child. If there's a senior citizen somewhere who can't pay for their prescription, who has to choose between medicine and the rent, that makes my life poorer - even if it's not my grandparent. If there's an Arab-American or Mexican-American family being rounded up by John Ashcroft without benefit of an attorney or due process, I know that that threatens my civil liberties. And I don't have to be a woman to be concerned that the Supreme Court is trying to take away a woman's right, because I know that my rights are next. It is that fundamental belief - I am my brother’s keeper, I am my sister’s keeper - that makes this country work.”

“In the unlikely story that is America, there has never been anything false about hope.”

“That is the one thing that makes me a Democrat, I suppose - this idea that our communal values, our sense of mutual responsibility and social solidarity, should express themselves not just in the church or the mosque or the synagogue; not just on the blocks where we live, in the places where we work, or within our own families; but also through our government.”

“This world is like a big classroom, and USA is the teacher, while other countries are the students, as one student tries to mess with the teacher, or does something really bad. The teacher shall teach him a nice lesson. Use your brain before you try to mess with the odds.”

“This election is about the past vs. the future. It's about whether we settle for the same divisions and distractions and drama that passes for politics today or whether we reach for a politics of common sense and innovation, a politics of shared sacrifice and shared prosperity. There are those who will continue to tell us that we can't do this, that we can't have what we're looking for, that we can't have what we want, that we're peddling false hopes. But here is what I know. I know that when people say we can't overcome all the big money and influence in Washington, I think of that elderly woman who sent me a contribution the other day, an envelope that had a money order for $3.01 along with a verse of scripture tucked inside the envelope. So don't tell us change isn't possible. That woman knows change is possible. When I hear the cynical talk that blacks and whites and Latinos can't join together and work together, I'm reminded of the Latino brothers and sisters I organized with and stood with and fought with side by side for jobs and justice on the streets of Chicago. So don't tell us change can't happen. When I hear that we'll never overcome the racial divide in our politics, I think about that Republican woman who used to work for Strom Thurmond, who is now devoted to educating inner city-children and who went out into the streets of South Carolina and knocked on doors for this campaign. Don't tell me we can't change. Yes, we can. Yes, we can change. Yes, we can. Yes, we can heal this nation. Yes, we can seize our future. And as we leave this great state with a new wind at our backs and we take this journey across this great country, a country we love, with the message we carry from the plains of Iowa to the hills of New Hampshire, from the Nevada desert to the South Carolina coast, the same message we had when we were up and when we were down, that out of many, we are one; that while we breathe, we will hope. And where we are met with cynicism and doubt and fear and those who tell us that we can't, we will respond with that timeless creed that sums up the spirit of the American people in three simple words -- yes, we can.”

“In the Catholic school, when it came time to pray, I would pretend to close my eyes, then peek around the room. Nothing happened. No angels descended.”

“The most important thing you need to do [in this job] is to have big chunks of time during the day when all you’re doing is thinking.”

“No, no. I have been practicing...I bowled a 129. It's like -- it was like Special Olympics, or something." --making an off-hand joke during an appearance on "The Tonight Show", March 19, 2009”

“We now live in a world where the most valuable skill you can sell is knowledge.”

“If you're walking down the right path and you're willing to keep walking, eventually you'll make progress.”

“How does the saying go? When two locusts fight, it is always the crow that feasts.' Is that a Luo expression?' I asked. Sayid's face broke into a bashful smile.  We have a similar expression in Luo,' he said, 'but actually I must admit that I read this particular expression in a book by Chinua Achebe. The Nigerian writer. I like his books very much. He speaks the truth about Africa's predicament. the Nigerian, the Kenya - it is the same. We share more than divides us.”

“All this marked them as vaguely liberal, although their ideas would never congeal into anything like a firm ideology; in this, too, they were American.”
