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 keaim what was lost here in 2008. I want to congratulate senator obama. Reporter after her defeat here in barak obama that all but ended her white house bid. I think what happened, she wan redemption and voters here in South Carolina want redemption. Ere 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 going to votem 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 te for bernie . H 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 blacks comprised more 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. 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 rarlce out of reach with more than half of the democratic delegat up t for grabs over the next month, many of them for the taking on tuesday. Lerister . Thanks. A loss by sanders in South Carolina wou deprive him of much needed momentum going into the super t uesday contests. Casey hunt is with the Sanders Campaign tonight in austin, texas. Reporter lester, good evening. The sanders camparry is bracing for the rse as pol are set to close in south carirolina. Sanders has hardly campaigned in South Carolina this week. His advisors are downplaying expectations. Instead, he is looking states. He is sharpening his attacks against llary clinton. If you ar 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 . Casey, thanks. Lets bring in our political director, chuck to. He has been looking at exit polls for ino sil ts into todays election. What are you seeing . I can tell you, its older, m e dive iberal. 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 election oral te 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 t had closer to 50 and under 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 70 in nevada, near 70 in new hampshire. This is an electorate that looks more like mocratic electorates across the country. Much less like an electorate that Bernie Sanders can do well. Coming into south rolina, Hillary Clinton and Bernie Sanders were quick to tailer their messages to africanamerican voters who as chuck pointed out make up more than half the electorate. I spoke to some black vointers in South Carolina who wanted the candidates to know that not every issue should be framed in blac. And white. The need you . They need my vote. Which is why when we spoke to kara she was taking her time deciding between Hillary Clinton and Bernie Sanders. For me, i have to feel brought in. Interest. Bernie is solid. Voters like this barber, the issue sanders built his campaign on are africanamerican issues. Healthcare. Everything he stands 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. 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 my life personally may be the same as a White American or a hispanic american. Do we do ourselves a disservice when we of africanamerican vote versus the rest of the vote . We do. Many of us have the i think of society and the media puts that the sepastion. Maha of us, were facing ghe 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 agreement on how to 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. We, re going to make some noise and hold you accountable. As we pointed out, cluaron a. D sanders face more contests in the south where t 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 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 1 won 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. Trump has all the 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 to crack. First with the Chris Christie endorsement. 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 greatk t president s ever if he sits down and puts together a good team. Reporter the kasian and rubio campaigns are talking about taking it to the convningention. 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 wont release his xes. Maybe his tax return shows that he doesnt quite have as much money as he says he does. In addition to that st year he wrote a big check to planned parenthood. Reporter in the last month, trump has proved he can turn out politically varied out as a political joveke in washington is looking more and more like a political ality. 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 yyou.
