“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.”

“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.”

“As president, I believe that robotics can inspire young people to pursue science and engineering. And I also want to keep an eye on those robots in case they try anything.”

“It was the call of workers who organized; women who reached for the ballot; a President who chose the moon as our new frontier; and a King who took us to the mountain top and pointed the way to the Promised Land. Yes we can!”

“I wish the country had fewer lawyers and more engineers.”

“To avoid being mistaken for a sellout, I chose my friends carefully. The more politically active black students. The foreign students. The Chicanos. The Marxist professors and structural feminists and punk-rock performance poets. We smoked cigarettes and wore leather jackets. At night, in the dorms, we discussed neocolonialism, Franz Fanon, Eurocentrism, and patriarchy.”

“Making products we sell around the world, stamped with three proud words, ‘Made in the USA!”

“And I would shrug and play the question off, unable to confess that I could no longer distinguish between faith and mere folly, between faith and simple endurance; that while I believed in the sincerity I heard in their voices, I remained a reluctant skeptic, doubtful of my own motives, wary of expedient conversion, having too many quarrels with God to accept a salvation too easily won.”

“There was something to what he said, for it was true that the people I met on the job were generally much older than me, with a set of concerns and demands that created barriers to friendship. When I wasn’t working, the weekends would usually find me alone in an empty apartment, making do with the company of books. I”

“A woman named Helen Keller fought her way through long, silent darkness. Though she could not see or hear; she taught us to look at and listen to each other. Never waiting for life to get easier, she gave others courage to face their challenges.”

“What had Frank called college? An advanced degree in compromise.”

“I'm inspired by the people I meet in my travels--hearing their stories, seeing the hardships they overcome, their fundamental optimism and decency. I'm inspired by the love people have for their children. And I'm inspired by my own children, how full they make my heart. They make me want to work to make the world a little bit better. And they make me want to be a better man.”

“Religious freedom doesn't mean you can force others to live by your own beliefs.”

“The absence of even rough agreement on the facts puts every opinion on equal footing and therefore eliminates the basis for thoughtful compromise. It rewards not those who are right, but those - like the White House press office - who can make their arguments most loudly, most frequently, most obstinately, and with the best backdrop.”

“What’s certain is that I don’t need the stress.”
