Now, the Iranian people are a great people, and Persian civilization is a great civilization. Iran has acted in ways that's not conducive to peace and prosperity in the region: their threats against Israel; their pursuit of a nuclear weapon which could potentially set off an arms race in the region that would make everybody less safe; their support of terrorist organizations in the past - none of these things have been helpful.

I've come to embrace the notion that I haven't done enough in my life. I've come to confirm that one's title, even a title like president of the United States, says very little about how well one's life has been led. No matter how much you've done or how successful you've been, there's always more to do, always more to learn, and always more to achieve.

The world only makes sense to me given my life and my background if, in fact, we're not just an assortment of tribes that can never understand each other, but that we're, rather, one common humanity that can meet and learn and love each other.

I think it's really important to enlarge the issue behind abortion. I have been serving for over two decades and I have seen year in and year out largely the Republicans voting against women's contraception, family planning.

America, we weaken our ties when we allow our political dialogue to become so corrosive that people of good character aren't even willing to enter into public service; so coarse with rancor that Americans with whom we disagree are seen not just as misguided but as malevolent. We weaken those ties when we define some of us as more American than others, when we write off the whole system as inevitably corrupt, and when we sit back and blame the leaders we elect without examining our own role in electing them.

I do think that all politicians today have to be more attentive to people wanting to be heard, wanting to have more control over their lives.
