I think, while it is true that the Hillary Clinton and I voted differently on the war in Iraq, what is important is that we learn the lesson of the war in Iraq. And that lesson is intrinsic to my foreign policy if elected president, is the United States cannot do it alone. We cannot be the policeman of the world. We are now spending more I believe than the next eight countries on defense. We have got to work in strong coalition with the major powers of the world and with those Muslim countries that are prepared to stand up and take on terrorism.

Let's talk about why, in the 1990s, Wall Street got deregulated. Did it have anything to do with the fact that Wall Street provided - spent billions of dollars on lobbying and campaign contributions? Well, some people might think, yeah, that had some influence.

The fossil fuel industry for too long has shifted enormous costs of carbon pollution onto the public.

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.

If there is a large voter turnout, not only do we retain the White House, but I think we regain the Senate. We win governors' chairs up and down the line. So I believe if you want to retain the White House, if you want to see Democrats do well across the board, I think our campaign is the one that creates the large voter turnout and helps us win.

There is far too little discussion in Washington about the collapse of the middle class , almost no discussion at all about the incredible income inequality and wealth inequality in this country, and the fact that we're moving toward an oligarch form of society.

The billionaires pay an effective tax rate lower than nurses or truck drivers. That makes no sense at all. There has to be real tax reform, and the wealthiest and large corporations will pay.
