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

“We are a people of improbable hope.”

“Conservatives may be right when they argue that the government should not try to determine executive pay packages. But conservatives should at least be willing to speak out against unseemly behavior in corporate boardrooms with the same moral force, the same sense of outrage that they direct against dirty rap lyrics.”

“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.”

“Ours is not the first generation to understand the dire need for health reform. And I am not the first president to take up this cause, but I am determined to be the last.”

“We went down into the dungeons where the captives were held. There was a church above one of the dungeons -- which tells you something about saying one thing and doing another. (Applause.) I was -- we walked through the "Door Of No Return." I was reminded of all the pain and all the hardships, all the injustices and all the indignities on the voyage from slavery to freedom.”

“What I would say to my successor is that it is important not just to shoot but to aim”

“I believe in evolution, scientific inquiry, and global warming; I believe in free speech, whether politically correct or politically incorrect, and I am suspicious of using government to impose anybody's religious beliefs -including my own- on nonbelievers.”

“We need to internalize this idea of excellence. Not many folks spend a lot of time trying to be excellent.”

“Libraries remind us that truth isn't about who yells the loudest, but who has the right information. Because even as we're the most religious of people, America's innovative genius has always been preserved because we also have a deep faith in facts.”
