Now, in practice, in daily social interactions, etc., there may be all kinds of biases and prejudices that are unspoken, that people aren't aware of, that affect who's hired, and who gets loans, and how kids are treated in school. But it's a powerful thing if you have on your side an idea that the overwhelming majority of people believe in because that's how you can build a consensus that's lasting.

We do not benefit from a relationship with China or any other country in which we put our values and our ideals aside.

The world doesn't just revolve around you. There's a lot of talk in this country about the federal deficit. But I think we should talk more about our empathy deficit.

Now, as a nation, we don't promise equal outcomes, but we were founded on the idea everybody should have an equal opportunity to succeed. No matter who you are, what you look like, where you come from, you can make it. That's an essential promise of America. Where you start should not determine where you end up.

To the extent that we've got a fiscal crisis right now, part of it is prompted by a bullheaded insistence on the part of the president, for example, that we should extend all of his tax cuts, make all of them permanent.

We wouldn't even be where we are had it not been that 70% of Hispanics voted for President Obama, voted Democratic in the last election. That caused an epiphany in the Senate, that's for sure. So all of a sudden we have already passed comprehensive immigration reform in the Senate. That's a big victory.

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.
