“Here's the truth: the Soviet Union had thousands of nuclear weapons, and Iran doesn't have a single one. But when the world was on the brink of nuclear holocaust, Kennedy talked to Khrushchev and he got those missiles out of Cuba. Why shouldn't we have the same courage and the confidence to talk to our enemies? That's what strong countries do, that's what strong presidents do, that's what I'll do when I'm president of the United States of America.”

“I stand here knowing that my story is part of the larger American story, that I owe a debt to all of those who came before me, and that in no other country on Earth is my story even possible.”

“I tossed a stick into the fire. “Attitudes aren’t so different in America,” I told Francis. “You are probably right,” he said. “But you see, a rich country like America can perhaps afford to be stupid.”

“The question we ask today is not whether our government is too big or too small, but whether it works”

“And that brings me to one last point. I've got a simple message for all the dedicated and patriotic federal workers who have either worked without pay, or who have been forced off the job without pay for these last few weeks. Including most of my own staff. Thank you. Thanks for your service. Welcome back. What you do is important. It matters. You defend our country overseas, you deliver benefits to our troops who earned them when they come home, you guard our borders, you protect our civil rights, you help businesses grow and gain footholds in overseas markets. You protect the air we breathe, and the water our children drink, and you push the boundaries of science and space, and you guide hundreds of thousands of people each day through the glories of this country. Thank you. What you do is important, and don't let anybody else tell you different.”

“The boarded-up homes, the decaying storefronts, the aging church rolls, kids from unknown families who swaggered down the streets - loud congregations of teenage boys, teenage girls feeding potato chips to crying toddlers, the discarded wrappers tumbling down the block - all of it whispered painful truths.”

“I think perhaps education doesn’t do us much good unless it is mixed with sweat.”

“I can no more disown (Jeremiah Wright) than I can disown the black community. I can no more disown him than I can my white grandmother – a woman who helped raise me, a woman who sacrificed again and again for me, a woman who loves me as much as she loves anything in this world, but a woman who once confessed her fear of black men who passed by her on the street, and who on more than one occasion has uttered racial or ethnic stereotypes that made me cringe.”

“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”

“available to millions, government”

“the underlying struggle - between worlds of plenty and worlds of want; between the modern and the ancient; between those who embrace our teeming, colliding, irksome diversity, while still insisting on a set of values that binds us together, and those who would seek, under whatever flag or slogan or sacred text, a certainty and simplification that justifies cruelty toward those not like 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.”

“Maybe the critics are right. Maybe there's no escaping our great political divide, an endless clash of armies, and any attempts to alter the rules of engagement are futile. Or maybe the trivialization of politics has reached a point of no return, so that most people see it as just one more diversion, a sport, with politicians our paunch-bellied gladiators and those who bother to pay attention just fans on the sidelines: We paint our faces red or blue and cheer our side and boo their side, and if it takes a late hit or cheap shot to beat the other team, so be it, for winning is all that matters. But I don't think so. They are out there, I think to myself, those ordinary citizens who have grown up in the midst of all the political and cultural battles, but who have found a way-in their own lives, at least- to make peace with their neighbors, and themselves. ...I imagine they are waiting for a politics with the maturity to balance idealism and realism, to distinguish between what can and cannot be compromised, to admit the possibility that the other side might sometimes have a point. They don't always understand the arguments between right and left, conservative and liberal, but they recognize the difference between dogma and common sense, responsibility and irresponsibility, between those things that last and those that are fleeting. They are out there, waiting for Republicans and Democrats to catch up with them.”

“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.”

“That's what the leadership was teaching me, day by day: that the self-interest I was supposed to be looking for extended well beyond the immediacy of issues, that beneath the small talk and sketchy biographies and received opinions, people carried with them some central explanation of themselves. Stories full of terror and wonder, studded with events that still haunted or inspired them. Sacred stories. ”
