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

“Change is never easy, but always possible.”

“For in the end laws are just words on a page - words that are sometimes malleable, opaque, as dependent on context and trust as they are in a story or poem or promise to someone, words whose meanings are subject to erosion, sometimes collapsing in the blink of an eye.”

“By dint of vision, and determination, and most of all faith in the redeeming power of love, he endured the humiliation of arrest, the loneliness of a prison cell, the constant threats to his life, until he finally inspired a nation to transform itself, and begin to live up to the meaning of its creed.”

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

“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.”

“A lot of shelter dogs are mutts like me.”

“There is no excuse for not trying.”

“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”

“What Washington Needs is Adult Supervision.”

“Everybody knows that it makes no sense that you send a kid to the emergency room for a treatable illness like asthma. They end up taking up a hospital bed. It costs when, if you, they just gave, you gave, treatment early, and they got some treatment, and uhhh a breathalyzer, or uhh, an inhalator, not a breathalyzer...”

“right; maybe once you stripped away the rationalizations, it always came down to a simple matter of escape. An escape from poverty or boredom or crime or the shackles of your skin.”
