That is the nature of democracy. It is hard. It is not always inspiring.

Here in Europe some of the challenges have to do with structures that are so complicated. You've got Brussels, and you've got parliament, you've got councils and then you've got national governments. So people sometimes don't feel as if they know who's making decisions, and the more that we can bring people in and engage them, the better. Some of it is also cultural and social, people's sense of identity.

If you think that we've overregulated in the environmental space what I can show you is that we have tripled the amount of wind power in this country, increased by tenfold the amount of solar power. We are producing as much oil and gas as we've ever produced.

Every decision, every debate, no matter how important it is, with the same question: 'What does this mean for the next election? What does it mean for your poll numbers? Is this good for the Democrats or good for the Republicans? Who won the news cycle?' That's just how Washington is. They can't help it. They're obsessed with the sport of politics.

We can seize this future together because we are not as divided as our politics suggests.

More people are realising that ISIL's not a caliphate. It's a crime ring.

We could come together, Democrats and Republicans, to find practical, commonsense solutions to health care, to education, to energy issues, because although I'm a proud Democrat, I'm a prouder American. And I think all of us believe, regardless of our party affiliations, that this is a critical time, where we've got to solve big problems.
