Trump stayed away from we move on to the democrats. Just t t days before their caulks in nevada where Hillary Clinton and Bernie Sanders locked in a dead heat. Abcs cecilia vega tracking that tight battle. Good morning, cecilia. Reporter george, good morning to you. This is not where Hillary Clinton wants to be right now. Those caucuses right around the corner and nowhe is facing the very real possibility that she could lose her second state in a row. This morning, polls showing Hillary Clintons battle for nevada could be a pho finish. But she is putting her best face forward telling vogue magazine that getting the female vote is no slam dunk. Saying women are very judgmental about one another. Clinton also revealing one weakness in the campaign, herself. Im great at advocating for other people, she says, but im not so good at really promoting myself. I just find it hard to do. Now both clinton and Bernie Sanders are trying to promote themselves to minority voters ahead of nevadand South Carolina. Clinton running this new ad ill do everything i can to help, okay . Reporter and here she is hand in hand with the tearful mother of sandra bland, the chicago woman whose death in a jail cell sparked outrage. Im one of those mothers who met with her and was able to make it through. Reporter with clinton and sanders now in a virtual tie we headquarters to ask her Campaign Manager about those polls. What is Bernie Sanders doing in nevada that youre not . Hes aheadad right now. Youd have to ask him what hes doing. We are executing on our strategy. Reporter that strategy, an army of thousands of volunteers in nevada now trying to convincee voters to caucus. Your prediction for that state right nownowing these polls show what they show . Its going to be very, very cle. Were going to pull out but its going to be very, very close. Reporter some confidence. Bernie sanders took a break from the trl. Both sides back in nevada today. To visit her housekeeping staff. Theyre locked in a battle for latino and minority voters. Matt dowd, lets start with the publicans. I want to put up that nbc National Wall street poll showing ted cruz ahead or basically tied with donald trump right now. Very big shift. Youre not really buying it. Its an outliar. Maybe its a scientist that discovered a new planet whether everybody thinks theres stu on the camera lens. If you look at every single other poll donald trump has a doubledigit lead and if that poll was true donald trump would not be ahead in every single South Carolina poll. They mayave discovered something new trend, i doubt it. I think whats going to happen well have saturday and see new polls that show donald trump with the same lead we thought he had. Big battle if youreight about South Carolina, big battle for second, third and fourth place. What kind of difference is this nikki haley endorsement going to make to marco rubio . Its like a nascar race and shes drafting for rubio and i asked her Campaign Manager about that and he smiled. Theyre looking ahead to South Carolina where they feel much more confident looking at super tuesday where theyre confident there, but, t optics of another loss, a potential loss in nevada do not look good. This is a state she probably should be winning. Shes got more volunteers there, a second loss in a row is not where they want to be if that happens. On top of that what will that do to the South Carolina contest just a week later . These are not dominos on their own. Theyre dominos that fall in a row. If Bernie Sanders wins nevada, it obviously affects South Carolina. I dont think it causes him to win it but this whole race is a series of dominos that affect the previous and following domino. In the meantime, he gets momentum. Donald trump calling on jebeb bush to get out. Were losing our lights right there. Thats it. Theyre done with us. If marco rubio gets by jeb bush on saturday prett much the end of the line for jeb bush. I think the jeb bush folks are probay moving in a direction of now of when do we decide to get out of this race. I think they look at the polls and understand whats happening in South Carolina, very limited idea that theyll have success. My guess is theyre starting to make the plan for the long exit out of this race. Thats my guess. Hope that wasnt a signal for us to get out of this race. Back to amy. Thank you, george. Light.
