In fact, climate change is directly related to the growth of terrorism.

In America, we are living in a society which is moving more and more toward an oligarchic form of society where government is dominated heavily by big-money interests.

People are hungry, and they're hurting and they're very, very worried about their children. Will their kids ever pay off their student debt? Will their kids ever get a decent-paying job? I think Democrats have got to be running a grass-roots campaign - mobilizing people and being prepared to take on the 1 percent with an agenda that speaks to the needs of ordinary workers.

If people envisage me in the Senate they might think of me as someone who would emulate Paul Wellstone, fighting for the issues he fought for. He was a good friend of mine. We'll be trying to do a couple of things. One is fighting for national health care. Another is fighting to raise the minimum wage to a living wage, and changing our trade policies.

Our goal there, in my view, is to work and lean strongly on China to put as much pressure. China is one of the few major countries in the world that has significant support for North Korea, and I think we got to do everything we can to put pressure on China. I worry very much about an isolated, paranoid country with atomic bombs.

The future of the Democratic Party, the future of this country is involving young people in the political process, getting them to stand up for their rights, dealing with student debt, which I got to tell you is just crushing people all over this country, making public colleges and universities tuition free, those are the ideas we are bringing out, demanding the wealthy and large corporations start paying their fair share of taxes. This is what younger people, working class people want. That is the future of the Democratic Party.

No president, not the smartest, best human being in the world can do it alone. You cannot take on this, the power that is in Washington, to billionaires and lobbyist, the military industrial complex, all of this money and power, you can`t do it. You need a mass movement of American who are looking in congress and we say directly.
