“I've been fighting with Acorn, alongside Acorn, on issues you care about, my entire career.”

“We may come from different places and have different stories, but we share common hopes, and one very American dream.”

“In my daughters I see her every day, her joy, her capacity for wonder. I won’t try to describe how deeply I mourn her passing still. I know that she was the kindest, most generous spirit I have ever known, and that what is best in me I owe to her.”

“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.”

“For us to respond in that way to hateful speech... we empower the worst of us .. to create chaos around the world.”

“Finally, there are the dangers inherent in any autobiographical work: the temptation to color events in ways favorable to the writer, the tendency to overestimate the interest one’s experiences hold for others,”

“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.”

“Nothing can stand in the way of the power of millions of voices calling for change.”

“I’ve just concluded that for me personally it is important for me to go ahead and affirm that I think same-sex couples should be able to get married.”

“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.”
