greenville, south carolina. today, the candidates put their faith in christian conservatives eight days before the primary in ys south carolina. and here's julianna goldman. >> i think that life is divinely inspired. >> reporter: in a state where or faith is central to many voters, republican presidential candidates have proclaimed their beliefs on the stump-- >> i'm a christian and i converted to catholicism. >> i discovered my purpose by discovering the lord. >> reporter: on the airwaves. >> to use gifts we've been given. >> it's a faith and family forum. gi >> reporter: and at a religious

reporter: can you talk a little bit about the role of faith in south carolina in this primary? >> there are there are a lot of faith value voters here's for sure. and we'll have chance to share my life journey and how faith has been important. >> reporter: self-described re evangelicals are born-again christians make up 65% of south carolina republican primary voters four years ago. while cruz won the evangelical vote in iowa, donald trump won it in new hampshire. that may explain why in a state known for its rough-and-tumble politics, trump and his conservative credentials have become a feeding frenzy. >> there is nothing conservative about donald trump. >> look past the boasting and you'll see right through him. >> reporter: on twitter, trump turned the tables on his anti- in can ted cruz be an evangelical christian when he lies so much and is dishonest? negative tv ads here in south carolina. getting hit from all sides you can expect him to try to make up g for that on the debate stage tomorrow night. o >> pelley: julianna goldman, thanks. and speaking of tomorrow night's debate, john dickerson will be s the moderator, and he's joining us now. or john, what are you expecting? >> reporter: well, i'm expecting the candidates to have a presidential demeanor on the outside and on the inside, a roiling desire to do battle. usually on a debate stage, the candidates want to look presidential because they don't want to come across as too aggressive. on the other hand, the stakes are very high here in south carolina, and there are two different kinds of battles going on. t there's donald trump's battle wi with ted cruz, which has gotten nasty and personal over who is more conservative, and over co questions of faith. ld donald trump tweeted about cruz's christianity. then there is the battle between en the mainstream alternatives, those three candidates -- bush, al kasich, and rubio. they are trading exchanging counter-charges almost by the issues -- medicaid, and what's nt id be president? so we hope when it's all said and done while there will be a er lot of heat there might also be some light. >> pelley: and with the winnowing that's occurred with the primaries and caucuses, it there will just be six candidates now on the stage, a very consequential debate. and that debate will begin at tomorrow evening at 9:00 eastern time, 8:00 central.

at last night's debate. universal health care coverage. >> reporter: she is embracing ge his vision but panning his plans in detail. >> you need to level with people. every progressive economist who e has analyzed that says the ana numbers don't add up. it would probably increase the size of the federal government by about 40%. >> that is absolutely inaccurate. secretary clinton has been going in around the country saying, "bernie sanders wants to dismantle the affordable care act. e people are going to lose their medicaid." we're not going to dismantle anything. >> reporter: and with south carolina's minority-heavy ca primary looming, she is accusing sanders of the undermining the nation's first black president. >> in the past he's called him ti disappointment. the kind of criticisms we hear from bernie sanders about our e ki president i expect from republicans. i do not expect from someone t running for the democratic nomination to succeed him. m >> madam secretary, that is a fo low blow. ec i have worked with president h but you know what? last i heard, we lived in a democratic society. last i heard, a united states senator had the right to disagree with the president. >>

carolina, freezing temperatures turned this water fountain into a giant popsicle. temperatures are expected to to plunge to two degrees in new york on sunday. pedro morales says he's invested in a cheap ski mask to stay warm. >> they're great. and for $5, that's a bargain in new york city. >> reporter: and here in scranton, these houses are likely to remain on ice for several more days, scott. that's because temperatures are freezing here until tuesday. >> pelley: michelle miller, thanks very much, michelle. police are trying to figure out why a man armed with a machete attacked people last

people and sent 12 million fleeing from their homes. this deal would be a breakthrough, except it isn't pt immediate, it isn't permanent, and it doesn't include all the es hostile forces. holly williams is in turkey tonight. holly, tell us some more. >> reporter: well, scott, this would be the first cease-fire in syria's civil war, agreed to by involved in the conflict. and hopefully, it will allow food and aid to get into places that are cut off right now because of fighting. but it's not clear whether the syrian regime will actually comply, and this temporary cease-fire may not start for another week, which allows the regime to continue its offensive around the city of aleppo, which has already driven tens of en t thousands of people from their homes. there are fears that aleppo d could soon be besieged by the t regime, just like the town of madaya, where more than 40 people have already starved to death. those are the regime's tactics, and in an interview released an today, the syrian president, bashar al-assad, vowed to retake ar the entire country. he also rejected allegations of war crimes. . now, the regime's offensive is o backed by russian airstrikes and russia says despite cease-fire it will continue those strikes against terrorist groups. and that's another problem because when russia has said that in the past, it's also some of those rebels are very skeptical about the cease-fire plan, and the agreement does not include isis and other extremist groups. >> pelley: not likely to be the end that the world's been hoping for. holly williams in turkey tonight. holly, thank you. on our southern border, we are now seeing a new wave of f immigration from mexico, but what's notable is who is making the journey and why. we asked mark strassmann
