Good reason to stay inside. Dylan, thank you. Turning to politics where that is the site of the next republican debate. With the attacks getting more heated on the campaign trail, anything can happen. We have coverage for you with nbcs Hallie Jackson covering the republicans. Hallie, good morning. Reporter good morning. This morning, the candidates are getting ready for the debate. The stage is the smallest with six people left in the race. South carolina has a reputation of being a rough and tumble state. Dont expect tonight to be different with republicans already looking ready to rumble. Reporter in front of a rowdy crowd, donald trump taking aim at jeb bush. He has a vicious streak. Reporter online, a different target as trump warns ted cruz on twitter, if he doesnt quote clean up his act, stop cheating and doing negative ads, trump will sue him for not being a there is more than a little irony than donald calling somebody nasty with the insults and vulgarities. Reporter cruz and trump battling for evangelicals in South Carolina. And on the air waves, ad wars intensify. This one from trump on illegal immigration immigration. His killer, an illegal immigrant. Reporter and this from cruz hit not a republican rival, but Hillary Clinton. The ad spoofs the movie office space but a different kind of film that has cruz explaining why he yanked this off the air. Vote for a pretty face next time. It happened with one of the actresses who was there had a more colorful film history than we were aware. Reporter the actress the she has no hard feelings. I have no ill will against ted cruz. He has a job to do. Im a middle class working girl. Reporter the job tonight for marco rubio, prove he can bounce back from New Hampshire. Rubio says he is ready. We have to have perspective here. I had one answer i would have done differently. Reporter Rubio Campaign aide tells me he is eager for tonight and ready to take on attacks directly rather than pivot to president obama. Watch for jeb bush to try to land some punches tonight. South carolina hoping its the comeback state for bush. Look for john kasich keeping up momentum after the second place finish in New Hampshire. His tactic is different, guys. He is looking to stay positive and stay above the fray. Hallie jackson, thank you. Elise jordan is a political adviser. Thank you for being here. Thank you for having me. There are six candidates left. What advice would you give the candidates . Given this is the ninth debate, we know the patterns with each and how they project themselves. People havent done well trying to attack. You look at what Chris Christie did with marco rubio. It was a very effective attack and really harmed rubio, but christie is out. He was a suicide bomber on stage and took rubio out. That is the fine balance these candidates have to navigate between being too nasty and showing a positive vision and keeping in the race. You mentioned marco rubio. Him tonight. Yes. He really needs to have a really strong performance. He needs to show he can go off there is a focus on that political background. He needs to show he can be more off the cuff and intelligent. Donald trump in South Carolina at last check, he was up around 16 points, i believe. Primary voters in that state are not just evangelical. Nearly 70 of the voters are evangelical. Donald trump did well with evangelical voters in iowa. How is a guy like donald trump doing well with the socalled god voters. It is interesting he is navigating that balance so well so far. I think part of what cruz knows with the opening there, when he did the new york values attack, that was not sailing in the wind. He knew that was effective. What im looking for tonight is trumps use of the foul language. This is the bible belt and that language in front of children is not going to go well. A lot to watch. Elise jordan, thank you.

His Campaign Sees minnesota with a history of electing more liberal candidates as a place where he could challenge clinton. But both spoke differently when we have got to be honest and to acknowledge we still have a very, very long way to go to create the nation that i know all of us believe we can create.
