“There's no such thing as a vote that doesn't matter.”

“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.”

“Hope -- Hope in the face of difficulty. Hope in the face of uncertainty. The audacity of hope! In the end, that is God’s greatest gift to us...A belief in things not seen. A belief that there are better days ahead.”

“Scientists and engineers ought to stand side by side with athletes and entertainers as role models.”

“At the moment that we persuade a child, any child, to cross that threshold, that magic threshold into a library, we change their lives forever, for the better”

“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.”

“What I’ve realized is that life doesn’t count for much unless you’re willing to do your small part to leave our children — all of our children — a better world. Any fool can have a child. That doesn’t make you a father. It’s the courage to raise a child that makes you a father.”

“This pleased Onyango, for to him knowledge was the source of all the white man's power, and he wanted to make sure that his son was as educated as any white man.”

“Change is never easy, but always possible.”

“The Cambridge police acted stupidly in arresting somebody when there was already proof that they were in their own home. . . . What I think we know — separate and apart from this incident — is that there is a long history in their country of African-Americans and Latinos being stopped by law enforcement disproportionately, and that’s just a fact.”

“No one is pro-abortion. ”

“And to all those who have wondered if Americas beacon still burns as bright - tonight we proved once more that the true strength of our nation comes not from our the might of our arms or the scale of our wealth, but from the enduring power of our ideals: democracy, liberty, opportunity, and unyielding hope. For that is the true genius of America - that America can change. Our union can be perfected. And what we have already achieved gives us hope for what we can and must achieve tomorrow.”

“We don't ask you to believe in our ability to bring change, rather, we ask you to believe in yours.”

“And you won’t have to wake up at four in the morning,” she said, a point that I found most compelling.”

“In reaffirming the greatness of our nation, we understand that greatness is never a given. It must be earned. Our journey has never been one of shortcuts or settling for less. It has not been the path for the faint-hearted, for those who prefer leisure over work, or seek only the pleasures of riches and fame. Rather, it has been the risk-takers, the doers, the makers of things -- some celebrated, but more often men and women obscure in their labor -- who have carried us up the long, rugged path towards prosperity and freedom.”
