Santa clara, california. Im a star. Thats the overnight news for this tuesday. For some of you the news continues. For others check back with us a little later for the morning news and cbs this morning. From the Broadcast Center in new welcome to the overnight news. The people of New Hampshire head to the polls today to cast the primary votes in the race for the white house. Much of the state is in the grips of a snowstorm and that should affect voter turnout. The latest polls show Bernie Sanders and donald trump with commanding leads. For the gop, donald trump is at 30 . With john kasich a strong push at 14 , followed by marco rubio, jeb bush and ted cruz. For the democrats, sanders over Hillary Clinton by 22 points. John dickerson spoke to both Democratic Candidates for face the nation. Senator, while you were in new york, North Koreans launched as president you would face that thing all the time. Very often. What secretary clinton is saying you dont have the experience to be ready for those kinds of challenges on day one . Well thats what she said about barack obama in 2008. Turned out not to be true. Im impressed by the quality of his Foreign Policy. Furthermore, on the most happen, in fact, did happen. On the other hand. Secretary clinton voted for the war. So, i think it is not just experience, obviously, she has been a secretary of state for four years. Bit is judgment as well. But it is judgment as well. Provide great Foreign Policy for the people of the United States. There is a crisis you need to instill confidence in the in looking at the debates it is clear youre confident talking economic issues, income inequality. When it comes to Foreign Policy, you are less confident. How would you, how would you Show Confidence as a president on the issues . John, i think that is a media narrative that goes round and round and round. I dont accept that media narrative. Again on the most important issue of our time. I was right. Hillary clinton was wrong. This is the same argument made against barack obama in 2008. I will assemble a topnotch Foreign Policy team. And we will provide excellent and strong Foreign Policy for the people of the United States. What i believe right now is that we have got to learn the lessons of iraq. That its that the United States that we have to work in coalition, we have to work in coalition with major countries and with muslim countries whose troops will be on the ground. My main concern, terms of the mideast, is to make certain that the United States does not get involved in perpetual warfare in the quagmire of iraq and syria. In afghanistan. You have talked a lot about donations Hillary Clinton receives from service sector. In debate she called that an artful smear. What is your response to that . It is a fact. When in the last reporting period, her superpac received 25 million. 15 million from wall street. What is the smear. That is the fact. She says you cant point to a single vote that she changed or an opinion that she changed, can you . Nobody who has a superpac, gets money, republican or democrat from the pharmaceutical industry from fossil fuel history who said that money influences me. Its just, people have thrown millions and millions into the campaign, but there is no reason why theyre throwing that money into the campaign. I think, you know the American People know better. So i have never impugned a secretary clintons integrity. I like secretary clinton. But we have a corrupt Campaign Finance system. I am proud, i do not have a super pac. We have raised 3. 5 million individual contributions averaging 27 apiece. Barack obama received a lot of money from the same groups. Is he in the same fix as Hillary Clinton . It is a corrupt, it is a corrupt Campaign Finance system. Let me tell you something, john. At the very top of my list, of goals that i want to accomplish, as president of the United States. It does not mean that billionaires should be annal to en the townhall the other night you said the financial interests are not giving me very much money now. According to the Washington Post analysis, donors at hedge funds, banks, Insurance Companies and other Financial Services firms have given you at least 21. 4 million. 10 of what you raised. Thats a lot of money. Thats no the calculation that we have done. Thats somebodys analysis the i will not argue with it. What is really going on here, john is disturbing to me. Ill be frank with you. What the Sanders Campaign is trying to do is link donations to my Political Campaign or really donations to any ones Political Campaign with undue influence with changing peoples views and votes. I have never, ever done that. I really do resent the implication or i said the other it would be like saying, president obama who took probably more money from wall street, any democrat has in 2008 with his Successful Campaign was therefore, disqualified. We know that was not true. He signed the toughest, Financial Regulation since the 1930s with the dodd frank bill. You know this is a very artful smear. And i am just not going to sit and take it anymore. Are you saying on the questions that, people from the Financial Services industry have no greater access to you than anybody else . Im saying that i am available to and open to listening to people from all walks of life. I always have been. Ive always will be. Talk to the, if people want to donate to me. They know i called them out on the Mortgage Market mess before the great crash happened. It was not me, senator sanders who voted to deregulate swaps and derivatives which gave lyman brothers extra leverage one of the contributing factors to their collapse which obviously contribute to what happened in the great recession. We could take these step by step and try to unwind them. It doesnt change the basic facts. People know where i stand. I have rolled out. Toughest, effective effort to rein in Financial Abuse of anybody in the campaign. Goes further than dodd frank and glass steegle, and goes into shadow banking, hedge funds, carried interest loophole. That is full disclosure. I am on the record. If somebody in one of the firms wants to give me money. Hope they know theyre giving money to someone that makes sure they never wreck the economy again.
