[ William Ayers] is an example of what I'm talking about. This is a guy who lives in my neighborhood, who's a professor of English in Chicago who I know and who I have not received some official endorsement from. He's not somebody who I exchange ideas from on a regular basis.

My hope would be that, as we're moving through the world right now, we're able to get that psychological or emotional peace by seeing very concretely our kids doing better and being more hopeful and having greater opportunities.

People always - I think were surprised about me connecting with folks in small town Iowa. And the reason I did was - first of all, I had the benefit that at the time nobody expected me to win.

I think raising wages, investing in infrastructure, making sure that people have access to good educations that equip them for the jobs of the future. Those are all agenda items that would help alleviate some of those economic pressures and dislocations that people are experiencing.

Today, about 40 percent of America's carbon pollution comes from our power plants. There are no federal limits to the amount those plants can pump into the air. None. We limit the amount of toxic chemicals like mercury, and sulfur, and arsenic in our air and water, but power plants can dump as much carbon pollution into our atmosphere as they want. It's not smart, it's not right, it's not safe, and I determined it needs to stop.

Despite all the noise and hullabaloo - military cooperation, intelligence cooperation, all of that has continued. We have defended them consistently in every imaginable way. But I also believe that both for our national interests and Israel's national interests that allowing an ongoing conflict between Israelis and Palestinians that could get worse and worse over time is a problem. And that settlements contribute.
