Its the first contest in the south for democrats in the south they are competing for the africanamerican vote. On this business night. Clinton and sanders find themselves competing for attention with a republican candidate. Our team has it covered. First to South Carolina reporter Clinton Campaign officials feel confident. They are hoping to match or beat senator sanders win in new hampshire. That would give second clinton big momentum heading into super tuesday. Thank you so much, columbia. Reporter secretary clinton coasting to an expected win in the First Southern primary. For clinton, South Carolina is a key part of her southern firewall. Its a test for whether she can reclaim what was lost here in 2008. I want to congratulate senator obama. Reporter after her defeat here in barak obama that all but i think what happened, she wants redemption and voters here in South Carolina want redemption. There are thousands of voters here in South Carolina that were planning on voting for her. Then barak obama won iowa. They dont regret who they voted for, but now they are able to vote for who they thought they were going to vote for. Reporter many of the africanamericans who propelled obama to victory casting their ballots for clinton. Given you voted for obama, how does it feel to vote for clinton today . That same way. That feeling of excitement. Just ready to get the country moving in a more of a positive direction. Reporter why do you like hillary . I believe shes the most qualified. Reporter some feeling the bern. Why did you decide to vote for bernie . He said he will raise the minimum wage. Im a big fan of that. Reporter africanamericans make up a majority of the electorate here and in some super tuesday states. 2008 exit polls show than 50 of voters in georgia and alabama and nearly 30 in virginia and tennessee. Even while south carolinians voted, clinton and Sanders Campaigned in super tuesday states where they lobbed their sharpest attacks at republicans. It does bother me when i hear some of the rhetoric coming out of the republicans. You do have to be careful about what you say and how you say it. [ applause ] we can defeat trump and defeat him soundly. Reporter clinton officials are hoping that a big win here will help to put this race out of reach with more than half of the democratic delegates up for grabs over the next month, many of them for the taking on tuesday. Lester . Thanks. A loss by sanders in South Carolina would deprive him of much needed momentum going into the super tuesday contests. Casey hunt is with the Sanders Campaign tonight in austin, reporter lester, good evening. The Sanders Campaign is bracing for the worst as polls are set to close in South Carolina. Sanders has hardly campaigned in South Carolina this week. His advisors are downplaying expectations. Instead, he is looking ahead to super tuesday states. He is sharpening his attacks against Hillary Clinton. If you are going to give a speech to Goldman Sachs or other wall street institutions and if you give that speech behind closed doors, why dont you make those transcripts public . Reporter even more telling than that, he is going to be in minnesota as polls close in South Carolina. Thats one of the states he is looking to on that super tuesday map. He also wants to do well in massachusetts, vermont, colorado. All places where theres a lower share of minority voters. Lester . Lets bring in our political director, chuck todd. He has been looking at exit polls for insights into todays election. What are you seeing . I can tell you, its older, more diverse, less lebiberal. It does not favor Bernie Sanders. As you can see here, voters in South Carolina just 32 are under the age of 45. Look at the number in new hampshire. Over 40 were under the age of 45. Lets move to the breakdown among race. The electionoralte in 2008, 55 africanamerican. Look at the number. Over 60 at 61 . Theres some evidence it may be higher than that. Then look at the difference between South Carolina and the first three states here when it comes to the idea of continuing obamas policies. 70 in South Carolina want to continue president obamas policies. In the other three states, you had a thad in new hampshire. And then theres the overall ideology. This is the least liberal electorate of the first four states so far as you can see there. South carolina just 52 of democrats identify themselves as liberal. 70 in nevada, near 70 in new hampshire. This is an electorate that looks more like democratic electorates across the country. Much less like an electorate that Bernie Sanders can do well in. Coming into South Carolina, Hillary Clinton and Bernie Sanders were quick to tailer their messages to africanamerican voters who as chuck pointed out make up electorate. I spoke to some black voters in South Carolina who wanted the candidates to know that not every issue should be framed in black and white. The need you . Which is why when we spoke to kara she was taking her time deciding between Bernie Sanders. Feel brought in. No one tap mid bernie is solid. Barber, the issue sanders built his campaign on are africanamerican issues. The universal healthcare. Everything he stands for are the same things dr. Martin luther king stood for. South carolina is the first of several crucial tests in the south where africanamerican voters hold huge influence. The key constituency for both would be africanamerican women. Younger and older women. People like kara, a millennial who works for a nonprofit and are a ramona brown. A schoolteacher. You were a supporter from 2008 . I have been a Hillary Clinton. The fact that you were supporting Hillary Clinton and not obama in 2008 speaks against the notion that africanamericans its a mono linlic vote. Absolutely not. The issues that impact be the same as a White American or a hispanic american. Do we do ourselves a disservice when we talk about it in terms of africanamerican vote versus the rest of the vote . We do. Many of us have the same challenges. I think of society and the media puts that the separation. Many of us, were facing the same things. We have the same concerns. There remain issues that resonate more forcefully in black communities. For example, education. The incarceration. Those two are tied together. They are the issues clinton and sanders are largely in tackle. Can they convince voters that they mean what they say . It feels good to finally be acknowledged and recognized to know we have a voice and that now you need our voice. You have to listen. Were going to make some noise and hold you accountable. As we pointed out, clinton and sanders face more contests in africanamerican vote could prove key during this coming weeks super tuesday primaries. For the republicans, donald trump is being fed some of his own medicine tonight. Insults and taunts as his competitors struggling to gain traction with pulling out stops to halt his momentum as the candidates make a push. We get the latest from katie tur. Reporter marco rubio is getting personal. He is flying around on hair force one. I see him with makeup. Its like he is putting it on with a trowel. Amazing to me that a guy with the worst spray tan in america is tacking me for putting on makeup. Rubios 1won nothing. He couldnt get elected dog catcher in florida. Its time to open our eyes. We cannot allow a con artist to get access to the Nuclear Codes of the United States of america. Reporter the race getting dirty going into super tuesday. Momentum. He continues to lock up voter support with a campaign built around a border wall. Who will pay for that wall . Reporter the wall between the new yorker and republican establishment is starting trao cck. First with the Chris Christie endorsement. Now with endorsements from former Arizona Governor january brewer and maine Governor Paul Lepage who two weeks ago was meeting in secret with Party Leaders to try and stop trump according to the new york times. Now on a radio talk show saying we could do worse. I think he could be one of the greatest president s ever if he sits down and puts together a good team. Reporter the kasich and rubio campaigns are talking about taking it to the convention. I dont care if i get in my truck and drive around like did i when i ran for senate. Donald trump will never be the nominee. Reporter cruz is trying to attack trump from the right. Questioning why he maybe his tax return shows that he doesnt quite have as much money as he says he does. In addition to that last year he wrote a big check to planned parenthood. Reporter in the last month, trump has proved he can turn out politically varied voters. What may have started out as a political joke in washington is looking more and more like a political reality. As you can see, donald trump has just landed here in tennessee. A super pac supporting marco rubio is on the air in states across super tuesday states spending more than 6 million on negative ads against donald trump. Marco rubio himself has released his taxes. In it they say that rubio has made over 500 grand for the last four years that he was in national office. Most of that money coming from book deals. Katy tur, thank you.
