Can anyone catch trump . Can an establishment republican break out . The stage is set for the contest hosted by cbs news in greenville, South Carolina. Today, the candidates put their faith in christian conservatives eight days before the primary in South Carolina. And heres julianna goldman. I think that life is dwienl inspired. Reporter in a state where faith is central to many voters, republican president ial candidates have proclaimed their beliefs on the stump im a christian and i converted to catholicism. I discovered my purpose by discovering the lord. Reporter on the airwaves. To use gifts weve been given. Its a faith and family forum. Reporter and at a religious forum where today jeb bush, marco rubio faith is the most important influence in my life. Reporter and ted cruz addressed the faithful. I am saved by grace and it has transformed my life and my familys life. 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 voter heres for and well i have chance to share my has been important. Reporter selfdescribed evangelicals are bornagain christians make up 65 of South Carolina republican primary voters four years ago. While cruz won the evangelical vote in iowa, donald trump won is in new hampshire. That may explain why in a state known for its roughandtumble politics, trump and his conservative credentials have become a feeding frenzy. There is nothing conservative about donald trump. Look past the boasting and youll see right through him. Reporter on twitter, trump turned the tables on his antiestablishment rival saying, how can ted cruz be an evangelical christian when he lies so much and is disdis honest . Donald trump has pulled down his negative tv ads here in South Carolina. But, scott, now that hes getting hit from all sides you can expect him to try to make up for that on the debate stage tomorrow night. Pelley julianna goldman, thanks. Debate, John Dickerson will be the moderator, and hes joining us now. John, what are you expecting . Reporter well, im expecting the candidates to have a president ial demeanor on the outside and on the inside, a roiling desire to do battle. Usually on a debate stage, the candidates want to look president ial because they dont want to come across as too on the other hand, the stakes are very high here in South Carolina, and there are two different kinds of battles gog. Theres Donald Trumps battle with ted cruz, which has gotten nasty and personal over who is more conservative, and over questions of faith. Donald trump tweeted about cruzs christianity. Then there is the battle between the mainstream alternatives, those three candidates bush, kasich, and rubio. They are trading expharnlg countercharge almost by the hour over more substantive issues medicaid, and whats be president . So we hope when its all said and done while there will be a lot of heat there might also be some light. Winnowing thats occurred with the primaries and caucuses, there will just be six candidates now on the stage, a very consequential debate. And that debate will begin tomorrow evening at 9 00 eastern time, 8 00 central. Thats 6 00 in the west, right here on cbs. And we invite you to tweet us your questions using the hashtag goddebate. Democrats held their primary last night. He does not support the way i do building on the progress that the president has made. Reporter in rural South Carolina today, Hillary Clinton portrayed Bernie Sanders as one dimensional, part of a new strategy she unveiled at last nights debate. We both share the goal of universal health care coverage. Reporter she is embracing his vision but panning his plans in detail. You need to level with people. Every progressive economist who numbers dont add up. It would probably increase the size of the federal government by about 40 . That is absolutely inaccurate. Secretary clinton has been going around the country saying, Bernie Sanders wants to dismantle the Affordable Care act. People are going to lose their medicaid. Were not going to dismantle anything. Reporter and with South Carolinas minorityheavy primary looming she is accusing sanders of the undermining the nations first black president. In the past hes called him weak. Hes called him a disappointment. The kind of criticisms we hear from Bernie Sanders about our president i expect from republicans. I do not expect from someone running for the democratic nomination to succeed him. Madam secretary, that is a low blow. I have worked with president obama for the last seven years. But you know what, last i heard, we lived in a democratic society. Last i heard, a United States disagree with the president. Reporter clinton supporter and former secretary of state madeline awl priet apologized tonight for saying, theres a special place in hell for women who dont help other women. She acknowledged in an oped in this context it offended some women who arent voting for Hillary Clinton. Pelley nancy cordes, thanks very much. It looks chilly in South Carolina where nancy is. And another big story tonight is the cold snap in the northeast. Temperatures are expected to bottom out sunday morning, possibly hitting record lows in philadelphia, new york, and boston. In saranac lake, new york, wind chills could drop below minus 40. Michelle miller is chilling in stranton, pennsylvania. Reporter it was a striking image house after house encased in ice. At about 2 30 in the morning, the water main burst, shooting water 20 feet into the air and shutting down two blocks. Freeze set in. Large icicles hung from street signs, trees and power lines. That worries homeowner oscar velez. Im just concerned that people are going to slide and get hurt or get hit by those big icicles there hanging. Reporter from the midwest to the deep south, there was no escaping the arctic blast. Today in greenville, South Carolina, freezing temperatures turned this water fountain into a giant popsicle. Temperatures are expected to plunge to two degrees in new york on sunday. Pedro morales says hes invested in a cheap ski mask to stay warm. Theyre great. And for 5, thats a bargain in new york city. Reporter and here in scranton, these houses are likely to remain on ice for several more days, scott. Thats because temperatures are not expected to rise above freezing here until tuesday. Pelley michelle miller, thanks very much, michelle. Police are trying to figure out attacked people last night in a restaurant in columbus, ohio. Four people were hurt, one critically. Jeff pegues is following this. Reporter police say the assault has the hallmarkes of a terrorisminspired attack. Michael woods is deputy chief of the Columbus Police department. A lone individual, machete going into a public place, committing an assault on people that he apparently does not know. Those are the things that that give us concern. Reporter investigators say last night, 30yearold Muhammad Barry went to this mediterranean restaurant and asked questions about the israeli owner and the food. He left and then returned half an hour later with a machete. In 911 calls, witnesses described barry slashing diners. Reporter barry led police on a fivemile car chase before he was shot and killed after an officer. Law enforcement sources tell cbs news that barry had been on their radar before, and that is why is Columbus Police quickly notified federal authorities after that attack. Scott, weve also learned that he was here in the u. S. On a green card. Pelley jeff pegues, thanks. Overnight, the u. S. And russia hammered out a deal to stop the fighting in syrias catastrophic civil war that has killed 260,000 people and sent 12 million fleeing from their homes. This deal would be a breakthrough, except it isnt immediate, it isnt permanent, and it doesnt include all the hostile forces. Holly williams is in turkey tonight. Holly, tell us some more. Reporter well, scott, this would be the first ceasefire in syrias civil war, agreed to by all of the key outside countries 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. Syrian regime will actually comply, and this temporary ceasefire 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 thousands of people from their homes. There are fears that aleppo could soon be besieged by the regime, just like the town of madaya, where more than 40 people have already starved to death. Those are the regimes tactics, and in an interview released today, the syrian president , bashar alassad, vowed to retake the entire country. He also rejected allegations of war crimes. Now, the regimes offensive is backed by russian airstrikes and russia says despite ceasefire it will continue those strikes against terrorist groups. And thats another problem because when russia has said that in the past, its also targeted americanbacked rebels. Some of those rebels are very skeptical about the ceasefire plan, and the agreement does not include isis and other extremist groups. Pelley not likely to be hoping for. Holly williams in turkey tonight. Hole, thank you. On our southern border, we are now seeing a new wave of immigration from mexico, but whats notable is who is making the journey and why.
