I worry very, very much about an isolated country. That's what makes me nervous. Russia lives in the world. China lives in the world. North Korea is a very, very strange country because it is so isolated, and I do feel that a nation with nuclear weapons, they have got to be dealt with. Dealt with effectively.

I think what the secretary Hillary Clinton has recognized is the American people are extremely angry about the power of Wall Street, the greed, the illegal behavior of Wall Street.

I fear very much for our kids, for low income people and for seniors.

We're going to stand with working people. We're going to take on the billionaire class. We're going the take on the drug companies and the insurance companies. We're going the take on Wall Street. That's where I think the future of the Democratic Party lies.

In terms of the nature of the continuation of the Cold War, which has gone on so long between Cuba and the United States, I applaud the president for aggressively trying to end it and I hope we will have not only full diplomatic relations, but that the trade embargo will end.

I believe what I call common sense gun reform. Plus, a revolution in mental health, making sure that if people are having a nervous breakdown, or are suicidal, or homicidal, they get the care they need when they need it. I think the vast majority of the American people can support and agenda composed of those features.

What does a political revolution look like? It means that 80 percent of the people vote in national elections, not 40 percent. It means that billionaires can't make unlimited campaign contributions and buy and sell politicians. It means that the U.S. government represents the needs of all the people, not just the 1 percent and their lobbyists.
