Right now. Nouns noints from nbc news World Headquarters in new york, this is nbc nightly news with lester holt. Good evening. There are two fewer candidates in the race for president tonight. Casualties of a stunning night in american politics in which onetime long shot Bernie Sanders crushed hill hill on his way to a 22point victory in a New Hampshire democratic primary and donald trump leading the rest of the republican field in the dust with a 19point win over his nearest competitor sending new Jersey Governor Chris Christie and Carly Fiorina to the exits. Both announcing today they have suspended their campaigns after poor finishes in iowa and New Hampshire. The New Hampshire survivors have now descended on South Carolina, site of one of the next critical faceoffs. Our Political Team has redeployed two. We begin our coverage with nbcs katy tur. Hi, katy. Reporter hi, lester. Things are about to get interesting. Im already told attacks are being prepped on Donald Trumps three marriages and stance on eminent domain. A new world out there. If New Hampshire wanted to see their candidate sit on its count, south carolinians want to know how they take a punch. Donald trumps 757 is flying a little higher tonight, soaring into South Carolina off trumps doubledigit victory in New Hampshire. We are going now to South Carolina. Were going to win in South Carolina. I love you all. Thank you very much. Reporter trump trouncing the field, beating second place john kasich by more than 50,000 votes. They want to see us take the country back. They want to see great deals, not horrible deals. Reporter a decisive victory but its path forward isnt easy. South carolina is a lot different from New Hampshire. In 2012 exit polling 65 of gop voters identified as evangelical or born again. A voting bloc that ted cruz is expected to excel with, just as he did in iowa. And while trump owned voters who called themselves independents in New Hampshire, just 25 of south carolinians see themselves that way. A lot of people here are shooting for the silver medal and giving donald trump the gold medal. Reporter like New Hampshire, trump has drawn big and enthusiastic crowds across this state. Its where he got roaring cheers for his muslim ban. Total and complete shutdown of muslims entering the united states. Reporter but historically its also a place thats rewarred organization and cunning maneuvering. Its going to be sporty. I mean, South Carolina takes elections real personally. Reporter like New Hampshire, trump has led every South Carolina poll since july, and now he can claim those numbers cant equal votes. Katy tur, nbc news, new york. Reporter im Peter Alexander in South Carolina. Kasich kasich reporter where john kasich is on his first stop after a stunning second place finish in New Hampshire. Thank you, john reporter the Ohio Governor insisting his positive message is resonating. The light overshadowed the darkness of negative campaigning last night in New Hampshire. Its really, really cool. Reporter how do you navigate the anticipated negative attacks . Im not going to let somebody pound me. I have a right to defend my snow flurry watching the results come in tuesday night, kasich was more refliskt. We plugged away, plugged away, the little engine that can. Reporter but in South Carolina this midwestern moderate faces a steep uphill climb in a state with far more christian conservatives, the target audience for ted cruz. The men and women of South Carolina, i believe, want a consistent conservative, somebody who is the same yesterday, today and tomorrow. Reporter jeb bushs days may be numbered without a strong South Carolina showing, calling on his brothers, the former president. Jeb bush is a leader who will keep our country safe. We can do this. We can do this together, and my pledge is i will run with heart as a candidate. I will not veer from what i believe to be true. I will stand on conservative principles. Reporter but so much for southern charm. A marco rubio adviser predicting this state is going to be a bloodbath. South carolina will be definitive and determinative and i need your vote. Come out and help us. I need your support. Reporter still south carolinians may avoid the establishment all together. They are looking for somebody thats going to say the things that they want to hear. The people in South Carolina are angry right now, and they want a candidate that reflects that. Reporter that candidate will not be Chris Christie or Carly Fiorina. As you noted both of them suspending their campaigns today. As for john kasich, Campaign Advisers tell me his goal here is to prejent jeb bush from turning the South Carolina primary into his comeback story. Lester. Peter, thank you will. On the democratic side of all this Bernie SandersCampaign Says he raised over 5 million since the polls closed last night. Now sanders is looking to broaden his appeal with minority voters while hill hill may shake up her campaign after her resounding loss. Weve got both campaigns covered starting with nbcs kasie hunt. Kasie . Reporter lester, good evening. These millions that made up the best fundraising day ever coming in small donations, averaging just 34 apiece, but senator sanders telling nbc news tonight he knows he still has a lot of work to do. Bernie sanders looking ahead. A day after he sent hill hill to stunning defeat in New Hampshire. Having breakfast with reverend al sharpton at an iconic harlem restaurant, blocks from where kline kline moved his office when he left the white house. It is very important that he sent a signal that on the morning after an historic victory that he would come to harlem and have breakfast with me. Reporter there are signs of a possible sanders coalition. Last night he won 83 of the youth vote and 73 of independents. But hill hill still has more minority support and the stakes ahead are big and more diverse n. Iowa and New Hampshire, over 90 of democratic voters were white, but not in nevada with a large latino population, or in South Carolina where a majority are africanamerican. Do you think its possible for to you win the democratic nomination if you dont convince more black voters to back you . Well, it is absolutely essential the africanamerican vote and the latino vote, both votes, enormously important. We intend to do very well in boast those communities reporter vermont senator making that pitch along with shooting some hoops today on the view. The reason well do well is our views on criminal justice in this country, and that is we have a broken criminal justice system. Reporter sanders already has strong support among working class white voters. If he can broaden his appeal his campaign believes he can keep winning. Thank you, New Hampshire. Reporter kasie hunt, nbc news, new york. Reporter im Andrea Mitchell covering the clinton campaign. I still love New Hampshire, and i always will. Reporter a team now considering big changes like adjusting their message. In her concession clinton echoing sanders trying to appeal to sanders supporters. I will fight to rein in wall street, and you know what . I know how to do it . Youre not going to find anybody more committed toy Aggressive Campaign finance reform than me. Reporter top clinton supporters tell nbc news they are alarmed by voters reason for abanding clinton, losing to sanders by honesty and trustworthiness and the potential first female candidate losing young women by 11 points and other women 59 points. Expect to hear her policies on taxes. I will raise your incomes but not middle class taxes. Reporter the campaign is dispatching kline kline to South Carolina, a state thats been fraught for him in the past, getting backlash from this attack by barack obama when he ran against hill hill in 2008. This whole thing is the biggest fairy tale ive ever seen. Reporter clintons hope nevada and South Carolina more diverse and where she now leads are a firewall. A lot will depend on the states top democrat, congressman jim clyburn. Im not ruling out an endorsement before the election. Im just ruling one out for this week. Reporter even though she lost big, clinton will get as many delegates as sanders from elected officials and tomorrow she will be endorsed by the congressional black caucus, a big boost for South Carolina and beyond. Lester. Andrea mitchell, thank you. Lets bring in our political director, the moderator of meet the press, chuck todd. Do any of the rules and experience of New Hampshire apply Going Forward . Well, not only do they apply. It could actually be a rerun in this respect, in the way that we thought New Hampshire was going to serve of to winnow the republican field, help determine to who would be the chief challenger to trump and cruz, now that role goes to south carolinian republicans. Many republican campaigns ive talked to today concede trump and cruz will be one and two and now its the race for third. This time on the democratic side in South Carolina, instead of clinton being the underdog. She plays the favorite and its sanders who is the underdag plight game of expectations so South Carolina, oddly enough, a rerun of New Hampshire. Chuck todd, thank you very much. We learned today that the Justice Department has filed a civil rights lawsuit against ferson, missouri, now that the city is balking at making changes in the wake of the Michael Brown shooting. The city agreed to provide Better Police training and change how its courts do business, but last night the city said some changes, including Higher Police salaries, would cost too much, so now the feds are going to court seeking an order that would force the city to make those changes. In a community outside baltimore two sheriffs deputies have been shot and called. It all began with a disturbance call when investigators say the suspect opened fire and hit one deputy inside a restaurant. The gunman identified at 67yearold david evans flood and shot another deputy before he was killed by police. There are some new warnings about the very real fire danger to airplanes posed by lithium ion batteries found in just about every cell phone and laptop and often shipped as air cargo. They have already been linked to deadly crashes and now the faa, the ntsb and the nations main pilot union are all warning against shipping large quantities of these batteries and as nbcs tom costello reports some want them banned on passenger flights worldwide. The dangers posed by lithium ion batteries on full display in this faa test. A bulk shipment of batteries burning so hot the planes Fire Suppression system is overwhelmed. Battery cargo fires have already been blamed for this catastrophic fire on board a ups cargo fire in philadelphia and the loss of two cargo planes that killed their crews in due buy and off korea. Now a top pilots union is calling for a total ban on all battery shipments. We have no Fire Fighting equipment on board that can fight this fire. If it lights of course, the only chance of a successful outcome that we have is to get the aircraft on the ground as soon as possible. Reporter while most u. S. Passenger airlines already ban bulk shipments of batteries, nearly every cell phone, laptop, tablet and dvd player carried on a plane comes with lithium batteries that can overheat. Already 2,100 cases of small fires on board passenger planes, some forced to make emergency landings. Today the ntsb said the risk posed by lithium ion batteries is growing and immediate and called for new battery shipping regulations. Were looking for separation of lithium ion batteries from flammable materials, and were also looking to reduce the amount of lithium ion battery. Reporter a shipment ban is opposed, instep for stringent packaging. Faa authorities could decide on tough new standards for shipping batteries. Tom costello, nbc news, washington.
