“It's in the misery of some unnamed slum that the next killer virus will emerge.”

“At a time when our discourse has become so sharply polarized, at a time when we are far too eager to lay the blame for all that ails the world at the feet of those who think differently than we do, it’s important for us to pause for a moment and make sure that we are talking with each other in a way that heals, not a way that wounds.”

“So, let us summon a new spirit of patriotism, of responsibility, where each of us resolves to pitch in and work harder and look over not only ourselves, but each other.”

“If they bring a knife to the fight, we bring a gun.”

“Malcolm X avait formulé un jour, le voeu que le sang blanc qui coulait en lui (...) soit expurgé. (...) Mais en ce qui me concernait, je savais que dans mon cheminement vers le respect de moi-même, jamais je ne pourrais réduire mon propre sang blanc au rang de pure abstraction. Car que supprimerais-je en moi par la même occasion, si je devais laisser ma mère et mes grands-parents à la frontière d'un territoire inexploré ?”

“There's a wonderful, perhaps apocryphal story that people tell about Daniel Patrick Moynihan, the brilliant, prickly, and iconoclastic late senator from New York. Apparently, Moynihan was in a heated argument with one of his colleagues over an issue, and the other senator, sensing he was on the losing side of the argument, blurted out: 'Well, you may disagree with me, Pat, I'm entitled to my own opinion." To which Moynihan frostily replied, "You are entitled to you own opinion, but you are not entitled to you own facts.”

“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.”

“It’s the founding ideals that the flag draped over my father’s coffin stand for." Truth: His father was buried in Kenya, never served in the U.S. military. Which flag draped his father’s coffin? And what ideals does the flag that draped his father’s coffin in Kenya stand for?”
