The day women all around the world wait eagerly to discover the new ways their husbands and this morning sponsored by toyota. Lets go places. Welcome to cbs this morning. The democratic president ial race is getting tighter. Hillary clinton and Bernie Sanders found more issues to fight about at last nights debate. This was their last showdown before the nevada caucuses and South Carolina primary. The candidates reached out to minority voters who are about to play a much larger role in the campaign. Nancy cordes is at the university of wisconsinmilwaukee where she covered last nights debate. Reporter good morning. Everyone was wondering if Hillary Clinton would retool her message after her big loss in New Hampshire and the answer is she did she embraced parts of the sanders world view and she acknowledged that the economy is rigged in favor of the 1 . But she also went into detail about why she thinks that his very ambitious plans to fix it wont work. I am not a singleissue candidate and i do not believe we live in a singleissue country. Clashed over health care, wall street donations, and their loyalty to the president. And many people will actually be worse off than they are right now. Final thought, senator . I think that is inkrak accurate inact accurate. Calling the president weak and a disappointment. Have you ever disagreed with a president . I suspect you may have. One of us ran against barack obama. I was not that candidate. Reporter the debate was in wisconsin but the candidates were clearly focused on the next primary in South Carolina, where africanamericans could decide the outcome. So Race Relations would be better under a sanders presidency than they have been . Absolutely. Because what we will do is say instead of giving tax breaks to billionaires, we are going to create millions of jobs for low income kids so they are not hanging out on street corners. Reporter clinton argued she legacy of the nations first black president. The kind of criticism that we have heard from senator sanders about our president , i expect from republicans and i could not expect from someone running for the democratic to succeed the president of the united states. Madam secretary, that was a low blow. Reporter i think once im in the white house, we will have enough Political Capital to be able to do that. Secretary clinton, youre not in the white house yet. Reporter that exchange reminded a lot of people of that Famous Exchange from 2008 when barack obama told Hillary Clinton she was, quote, likeable enough. Clinton was asked last night, gayle, why she lost among women in New Hampshire. She said her goal was to empower women to make their own choices, for somebody else. Thank you very much, nancy. The republican candidates will meet tomorrow night in South Carolina for a cbs news debate. Most of them are already in that key state criticizing each other. And pitching voters who will go to the polls a week from tomorrow. But donald trump was hundreds of miles away last night and he was speaking to about 10,000 fans at a rally in baton rouge, louisiana. Julianna goldman is outside of the peace center in greenville, South Carolina, the site of sooted saturdays debate. Reporter the stakes are high here and republican candidates are certainly upping the ante ahead of tomorrows gebtdebate. Donald trump was in louisiana last night but set his sights squarely on South Carolina. We have a big one coming up. Great place. South carolina. I think we will do very well. Reporter from the campaign trail to the airways South Carolina is looking like a fiveman slug fest. Dont listen to donald trump. Really. Dont listen to donald trump. Jeb bush has no foreign jeb is spending all of this time being negative. How do you think donald trump going to washington will solve anything . Bush says, i believe he is not a true conservative. These people are stupid reporter its donald trump who is emerging as a primary target. I just hope you doobleg thent believe the crap because its all crap, okay . They are lies reporter trump taking time to sign a baby at his baton rouge rally struck a softer tone yesterday and criticized an ad pulled by ted cruz. Cruz wasnt feeling the love. Rolling out this minutelong ad here. Yes, its donald trump. Its you and your cronies and government. Reporter antitrump superpac is distributing what they call a voters guide and switching Political Parties and ask can we trust donald trump to stand strong on key conservative issues . And been that way a long time. Reporter chip is in South Carolina where a local paper has set up a website to track underhanded tactics. This is for the long haul and if you come out of this primary and youre doing well, you can you can handle it on the national stage. That is part of it. Its a testing ground. Reporter so far at these debates, jeb bush has been the no aggressive on taking on trump. That is expected to change tomorrow night. Charlie, bush is also bringing in reinforcements his brother, former president george w. Bush will campaign with him on monday. We have inside the peace center, John Dickerson, a moderator for tomorrow nights debate and kim strasle will be one of the pannists. Good morning. Republicans and talk about the fights in the gop taking place now in South Carolina. Cruz versus trump. Well, thats right. So youve got cruz versus trump. Trump. That is at least two fights. And then those who are fighting to be the alternative hope to take on trump or cruz. Its basically three fights and its ranging all over the place on issues from veterans to values. There is some talk of who has better christian values and then, of course, there is the competency question, who has the experience, who has been tested and who can handle the presidency once they get there. We keep hearing that george bush is hitting the road for his brother. Is that an asset or liability for him, do you think, in South Carolina . Well, South Carolina is a place george w. Bush came back and in 2000 against john mccain and a lot of history here and a bit of organization here. Also the veterans here. There is a connection between him as a wartime leader. And also just the good feeling about the bush family. For the kind of voters that jeb bush is trying to turn out, its a good thing. He was even bragging hes a member of the establishment because of his brother and his father. Not something any candidate is doing this season. Debate and the New Hampshire results had on the numbers in South Carolina . Right now, trump looks like he is still way up and way ahead. Its a little still a little fully known. But at least in one survey i looked at this morning, and you know how these things are quite volatile, he is still way up. For . Well, i think down here, this is going to be a very different race than it has been in iowa or New Hampshire, because South Carolina is just a little bit more of a varied state. So there is a lot of talk down here because its a manufacturing state about jobs and the economy to a degree. You probably dont have in iowa or New Hampshire. I think as john referenced, there is a big veteran and active duty military presence here. So Foreign Policy is going to play a big role, a bigger role than it has in the past. But, also, those values voters in the evangelical community, we are back in a place after New Hampshire where that is, again, a very big focus and you hear but this debate will be slightly different than what we have had up in this now. These are postdebate questions. Postdebate from New Hampshire and postresults from New Hampshire. What about marco rubio . Has he been slowed down significantly . I think he is certainly been slowed down and he knows it. He admitted it. He is going to have to come down and look as though he is nimble on his feet. Be able to ask answer questions and not sound formlaic. He has come out more aggressive down here and hitting at his competitors more harder, particularly trump. I think youre seeing all of these guys had held back their fire on trump and gone after emp each other a lot but now training their guns on the top guy and he has a lot of incoming. Thank you, John Dickerson and kim strassel. Good to see you. Thanks, gayle. John dickerson and major candidates at tomorrow nights debate and starts on cbs at 9 00 eastern and 8 00 central. Then on face the nation john interviews donald trump and marco rubio here on cbs. Details this morning about the temporary ceasefire. John kerry says the pause in fighting the next week. The deal will allow food and humanitarian aid will reach to be reached. Margaret brennan has been told the deliveries could begin as early as today. Holly, good morning. Reporter this is the first ceasefire agreed on by all of the countries involved in the Syrian Civil War but its success is still doubtful, because the russians say they will continue their air strikes against terrorist groups, which they have said before, while also targeting americanbacked rebels. Of this agreement. Syrian civilians are, once again, paying with their blood, as the regime claws back territory from rebel fighters. Supported by russian air power. Russian air strikes, which only started in september, seem to have tipped the balance in syrias fiveyearlong civil war giving the regime the upper hand. This week, Regime Forces launched an assault on the town of tall rifat which had been a stronghold for the rebels, some of them armed by the u. S. We met abdul balul who runs a school in telerefat. The shelling and air strikes are random, he told us. Homes are destroyed and childrens bodies lie in shreds on the ground. From their ally, iran, have also nearly enincluded aleppo. Syrias biggest city before this war began. If the ceasefire plan doesnt succeed, 300,000 civilians could be cut off there as they were in the town of madia, under a siege by the regime. More than 40 people there have starved to death. Tens of thousands of syrians have fled the new offensive and tried to cross this border into the safety of turkey. But turkey already has more than 2 million syrian refuges and is reluctant to take any more. Holly williams along the turkish syria border, thanks. The u. S. Government is growing concerned that isis is using chemical weapons. We have a number of of incidences isil has used battlefield. Reporter artillery shells . Sure. Reporter isis has access to chemical artillery shells . There are reports that isis has access to chemical precursors am nirks that they can use. Reporter the cia believes that isis has the ability to manufacture small quantities of chlorine and mustard gas. And the capability of exporting those chemicals to the west . I think there is always a potential for that and why its so important to cut off the various transportation routes and smuggling routes that they have used. Reporter are there American Assets on the ground right now hunting this down . The u. S. Intelligence is actively involved and being a part of the effort to destroy isil and get as much insight into what they have on the ground inside of syria and iraq.
