I'm skeptical that [the Republicans] can do [something better with healthcare] mainly because for seven years now, including when we first tried to pass health care, I said to 'em, "Okay, if [Obamacare] doesn't work tell me what does."

My mother was the one constant in my life. When I think about my mom raising me alone when she was 20, and working and paying the bills, and, you know, trying to pursue your own dreams, I think is a feat that is unmatched.

Four years ago, I promised to end the war in Iraq. We did. I promised to refocus on the terrorists who actually attacked us on 9/11. We have. We've blunted the Taliban's momentum in Afghanistan, and in 2014, our longest war will be over. A new tower rises above the New York skyline, al Qaeda is on the path to defeat, and Osama bin Laden is dead.

I will set big goals for this country as president - some so large that the technology to reach them does not yet exist.""I will recruit new teachers and make new investments in rural schools, we'll connect all of America to 21st century technology and telecommunications.

I would not be running for President if I didn't believe with all my heart that this is what the vast majority of Americans want for this country. This union may never be perfect, but generation after generation has shown that it can always be perfected. And today, whenever I find myself feeling doubtful or cynical about this possibility, what gives me the most hope is the next generation - the young people whose attitudes and beliefs and openness to change have already made history in this election.
