Who won the final debate . Such a nasty woman. Well be right back with a this is a special edition of nightline. Inside the final 30. Good evening. Thank you for joining us. Tonight, donald trump and Hillary Clinton going head to head for a final time in culminating in trumps unprecedented declaration. Will it change minds . Heres abcs terry moran from the spin room in las vegas. Thanks, byron. That was a slugfest, quite a night here tonight. A proper debate and some big headlines. Lets get right to it. Jon karl, rick kline. John, what is the big head line what did you make of tonight . The fact that donald trump would not commit to accepting the results of this election is the biggest moment of that debate. But really theea this entire election, that as you know is the bedrock principle of american democracy, the loser concedes, the winner accepts, we move on. I agree, this was a singular moment in american debates to have that candidate out there saying, i may not accept that. To leave that lingering i think is going to have republicans squirming to try to explain that away. Donald trump needed to have a very big moment, he had it, but it was exactly the wrong kind of moment for him. This felt like a debate in a race that already ended. He seemed a little more i thought during the first half of this debate he was incredibly focused. He kept on the issues. He did not take the bait. As the debate went on he lost focus, he started to flail around. Thats when the big mistakes happened. Does it change the game at all . I think it ensures a bad story line for donald trump for these next couple of weeks. And it limits him. I think this was a play to his own base. In talking about the election results, talking about the issues, the namecalling even, i think its inherently restricting to wha can mean. I think he needs something dramatic to happen to change the course of this race. Right now he is on a path that heads in the wrong direction. He needed the big change and he didnt get it. But it was an entertaining debate. For the blow by blow in this slugfest lets go to david wright whos taking us through the big moments. Tonight, one final showdown. She should never have been allowed to run for the presidency. The dustup in the desert. Talking down our democracy reporter las vegas, nevada. Host of prize fights but none quite like this. Such a nasty woman. Reporter clinton called trump a hypocrite on the issue of saving american jobs. In fact, the trump holt ri h route here in las vegas was made with chinese steel. He goes around with crocodile tears about how terrible it is but he has given jobs to chinese steel workers, not American Steel workers. Shes been doing this do it over the last 15, 20 years . You were very much involved excuse me, my turn. Theres only one of us on this stage whos actually shipped jobs to mexico, because thats donald. Hes shipped jobs to 12 countries, including mexico. Reporter trump questioned the value of her experience. You do have experience, i say the one thing you have over me is experience, but its bad experience. Because what youve done has turned out badly. She pushed back on the notion that she has the wrong sort of experience. Absolutely. That. She then listed all the things that she was doing with what donald trump was doing. In the 1990s i went to beijing. And i said womens rights are human rights. He insulted a former miss universe, called her an eating machine. Give me a break. On the day when i was in the situation room, monitoring the raid that brought Osama Bin Laden to justice, he was hosting the Celebrity Apprentice. So im happy to compare my 30 its a line i think were going to hear over and over again the next 20 days. Reporter the two debated the significance of the boys on the bus. Grab them by the [ bleep ]. Reporter bully bushs access hollywood bus, of course. Mr. Trump, at the last debate you said your talk about grabbing women was just that, talk. And that youd never actually done it. And since then, as we all know, nine women have come forward and their consent. First of all, those stories have been largely debunked. Those people, i dont know those people. I have a feeling how they came and i believe it was her campaign that did it. Secretary clinton. Reporter clinton hit back. He held a number of big rallies where he said that he could not possibly have done those things to those women because they were not attractive enough for i did not say that, i did not say that. In fact, he went on is he goes after their dignity, their selfworth, and i dont think there is a woman anywhere who doesnt know what that feels like. So we now know what donald thinks and what he says and how he acts toward women. Thats who donald is. Nobody has more respect for women than i do. Nobody. Nobody has more respect reporter russian president Vladimir Putin had a cameo. Hed rather have a puppet as reporter tonight trump and clinton debated abortion. Sharp differences. I am prolife and i will be appointing prolife judges. I strongly support roe v. Wade which guarantees a constitutional right to a woman to make the most intimate, most difficult in many cases, decisions about her health care that one can imagine. Reporter but highminded by 2016 standards. This is the first time abortion has come up in any of these debates. While saying, in the ninth month you can take the baby and rip the baby out of the womb of the mother just prior to the birth of the baby. Well, that is not what happens in these cases. And using that kind of scare rhetoric is just terribly unfortunate. Reporter on other issues they went straight for the jugular. Immigration, for instance. When it comes to the wall that donald talks about building, he went to mexico. Didnt even raise it. He choked. First of all, i had a very good meeting with the president of mexico. Very nice man. We will be doing very much better with mexico on trade deals, believe me. The nafta deal signed by her husband is one of the worst deals ever made of any kind signed by anybody. Donald knows a lot about this, he used undocumented labor to build the trump tower. Were going to secure the border and once the border is secured at a later date well make a determination as to the rest. But we have some bad out. The term bad hombres trending on twitter, apparently a lot of people found it offensive a lot of people might not understand the connotation of that. So im going to lay it out there. This is not political, this is not partisan, this has nothithi to do with anybody running for office, its the word and the way it was used. It was derogatory, it was every time he talks. You are the one thats unfit. Reporter trump tried to use leaked emails from Clintons Campaign manager against her. John podesta said you have terrible instincts. Bernie sanders said you have bad judgment. I agree with both. You should ask Bernie Sanders who hes supporting for president , and he has said which is a big mistake. Hes campaigned for me around the country saying youre the most dangerous person to run for history, i think hes right. Reporter donald trump calls this a rigged election. The election is being rigged. They have rigged it from the beginning. The election is being rigged by corrupt media. Reporter tonight an astonishing moment. Trump refused to say if hell accept the results of the election. I will look at it at the time. Im not looking it now, ill look at it at the time. Are you saying urnot prepared now what i am saying is i will tell you at the time, ill keep you in suspense. Because thats horrifying reporter trump accused clinton of conspiring with the media against him. She shouldnt be allowed to run. Shes guilty of a very, very serious crime. She should not be howed to run. Just in that respect i say, its rigged. Reporter clinton suggested trump is just a sore loser by nature. There was even a time when he didnt get an emmoor for his tv Program Three years in a he started tweeting the emmys were rigged. Should have gotten it. This is a mindset. This is how donald thinks. And its funny but its also really troubling. How surprised were you that trump wouldnt promise to accept the results . I thought it was stunning. This is really a hallmark of our democracy. Both his daughter and his running mate said that they would commit to it. And there he said he was going debate concluded we grabbed matt dowd for instant analysis. Lets go over here where we can get a little more light. I didnt see them shake hands at the end, did you . No, they didnt shake hands. Not at all . Not at all. Not at the beginning and not at the end. Were you surprised to his answer about the question will you respect the results of the election . I was shocked. Ive never heard an answer like that in all the elections ive been involved in. Thats not part of the american tradition . No. My fear is that hes setting it up for a divide in the country that is heal. Its still 19 days left. Yes. As of tomorrow. Yes. Maybe hell come around. I think hes going to get serious criticism by frps over the next 48 hours. Really. Yeah. Up next, complete debate analysis from abc news political contributors l. D. Granderson and cokie rob bears. Who they say was the big winner tonight. Until i learned more about oncedaily xarelto. A latest generation blood thinner. Then i made the switch. Xarelto . Significantly lowers the risk of stroke in people with afib not caused by a heart valve problem. It has similar effectiveness to warfarin. Warfarin interferes with vitamin k and at least six blood clotting factors. Xarelto . Is selective targeting one critical factor of your bodys natural clotting function. For people with afib currently well managed on warfarin, like all blood thinners, dont stop taking xarelto without talking to your doctor, as this may increase your risk of a blood clot or stroke. While taking you may bruise more easily, and it may take longer for bleeding to stop. Xarelto may increase your risk of bleeding if you take certain medicines. Xarelto can cause serious, and in rare cases fatal bleeding. Get help right away for unexpected bleeding, unusual bruising or tingling. If you have had spinal anesthesia while on xarelto watch for back pain or abnormal bleeding. Tell your doctor before all planned medical or dental procedures. Before starting xarelto tell your doctor about any conditions, such as kidney, liver or bleeding problems. To help protect yourself from a stroke, ask your doctor about xarelto. Theres more to know. Xarelto. Recently, a 1954 mercedesbenz grand prix race car made history when it sold for a record price of just under 30 million. Makes history selling at just over 30,000. And to think this one actually has a surroundsound stereo. The 2016 cla. Lease the cla250 for 299 a month at your local mercedesbenz dealer. It was a contentious president ial debate but which candidate emerged the victor . Im joined by abc news political contributors l. Z. Granderson and cokie roberts. Theres lots to unpack. Cokie, start with you and trumps refusal to say whether he would accept the results the election. It was absolutely extraordinary. He said, i will look at it at the time. And then went into the medias so corrupt, they poison the minds of the voters, the stuff hes been saying on the campaign trail and at his rallies that gets everybody ginned up. We really did expect him when asked directly that he would say, of course i will accept the as his Vice President ial running mate has and as his daughter did. Put this in context. Have you ever no. Before you finish asking. Right, right . This whole campaign has been, have i ever . The answer is no. And ive been doing it a very long time. But really, this strikes right at the heart of our system. You know, we expect the peaceful transfer of power. Its one of the this made us great for a very long time. Even as a tiny Little Country at the beginning. We followed the constitution and accepted it and everybody thought it was extraordinary. And it is extraordinary. But we do it and we expect it. I think had that question been asked earlier in the debate, when he wasnt quite as agitated, perhaps the answer would have been different. At that point of the debate he was fullon enraged, angry, you could see it on his face. I think he was in a mood where he was saying, im digging in on weve seen that with him in all of these debates, where for the first 20 minutes to a half hour he does what all his advisers tell him to do. Right, right. Where hes calm and tries to be president ial and he tries to keep his face under control and all of that. And then he just goes off. Speaking of enraged, the moment that blew up on twitter was when donald trump used the word hombre. Whats your take on that . Cecilia vega talked about that, she talked about from friends and colleagues about that. Its par for the course, unfortunately, for what he has sewn into his campaign. There was a report last week during Celebrity Apprentice he was using the term uncle tom to describe an africanamerican. This is a pattern of his. Is it purposeful racist . Perhaps not for him. But what it is means that hes been living in a bubble for much of his life. These phrases hes been using his entire life, he doesnt know theyre offensive. You are a woman of the south. You have real sensitivity to race in this country. What do you make of how trump uses words . Well, i agree completely with l. Z. In this case, that he probably didnt even know how offensive it is. A lot of us dont know how offensive it is, to be honest. First of all, be careful. You know, which hes not. But secondly, put it in the context. Because after all, he started his are coming into this country and theyre rapists and drug i mean, thats the worst thing hes said, theyre rapists. One of the things trump had to accomplish tonight was he had to expand his reach to women. In particular, educated white women. With remarks like such a nasty woman, does that help him . No. Does he expand his base at all . It was interesting, i asked him a question on the air where he said to me, thats a nasty challenged. And of course in a debate thats what happens. And so as she continued to come after him, which she really did, he just couldnt table ke it. She called him putins puppet. Used sharp language. Where does she fall short tonight . For me two areas. First, i honestly believe she needed to make some sort of appeal to johnson voters. There are certain states in which she is with donald trump north carolina. North carolina, colorado, and johnson is polling very well. And there are things she could have said tonight i believe that could have maybe appealed to those voters saying, hey, dont go with johnson, hes not a bernie alternative, go for me. She didnt take that opportunity. Number two, i would have liabled to have seen her drill him harder on his economic plan. His whole campaign is based on immigration, and im a great businessman, i can turn the economy around. Drive the debt up more than yours, she should have attacked his plan and when Chris Wallaces question went there, hit that point harder that your plan is worse than my plan. Clinton was well prepared. Cokie, where do you think she fell short tonight . I agree she could have gone after i disagree with l. Z. About the johnson voters. We talked about this earlier. Right. Because its true in certain states, but thats the place where surrogates can make a tremendous difference. Boy are her surrogates out. They are really do and i think that a lot of those people just dont like her. And its very hard to convince them, like me. You know . Final question, who won tonight, and will it make a difference . I think Hillary Clinton won tonight. And it would have made a difference had she lost. Because all of the momentum was with her and if it had stopped that momentum, that would have made a difference. But i dont think that is the case. I agree. Moments which i think she sewed it up. Number one her response to the Supreme Court nominee, talking about abortion, talking about how personal it is for a woman. Number two, allowing donald trump to characterize women who accused him of sexual abuse as seeking fame and fortune. Women who have been sexually abused or raped are not coming public because of seeking fame and fortune, theyre seeking justice. L. Z. , cokie, thanks so much.
