She is a cheat. She never reported it. Shes a cheat. Reporter true to form, this race brought lastminute surprises down to the wire. Including one final twist to the fbis review of Hillary Clintons emails. The fbi sent a letter to congress. It said it had reviewed a large number of emails and based on our review, we have not changed our conclusions that we expressed in july with respect to secretary clinton. In other words, remember that never mind about that. Reporter trump is now back to his old complaint. So totally rigged system. Ive been saying it for a long time.

Campaigning is only part of how you win an election. The get out the vote operation, the doorknocking, and on election day having the machine on the ground to give rides to voters who may need it, thats traditionally how these races are won or lost in critical battleground states. Of clinton volunteers. New york is solidly blue. Packed onto a bus, foot soldiers in this ground war. Were going to beat trump, yes. Were going to have our volunteers hand out some of the scripts.

He just shot me a bird out his window. Out his sun roof. Reporter the group rocks up to clemmons, north carolina.

Weve got to push on now to get trump across the finish line reporter the enthusiasm here palpable. The dignitaries sign autographs i love your hat. And you even look better in it. Reporter and give smooche anything to get out the vote. Excited for tuesday . Reporter inside the event, one of our new friends turns on us. People are learning to rely on things other than just abc, nbc, and cbs. And i really dont want to make my friend from abc feel uncomfortable but the fact is the country is changing and the tides turning. Reporter crowd certainly abc is crooked enjoy it, relish it reporter as we get back on the bus, were all friends again. When i come here, it just touches my heart to see such enthusiasm.

Rogue one a star wars story. In theaters december 16th. Its difficult to see someone you love struggle. I miss out on lifes little moments. So i talked to my doctor and he prescribed latuda. There are many forms of depression. Latuda is fda approved to treat bipolar depression, which is different from other types of depression. In clinical studies, onceaday latuda was proven effective for many people struggling with bipolar depression. Latuda is not for everyone. Call your doctor about unusual mood changes, behaviors, antidepressants can increase these in children, teens, and young adults. Elderly dementia patients on latuda have an increased risk of death or stroke. Call your doctor about fever, stiff muscles and confusion, as these may be signs of a lifethreatening reaction, or if you have uncontrollable muscle movements, as these may be permanent. High blood sugar has been seen with latuda and medicines like it, and in extreme cases can lead to coma or death. Other risks include decreased white blood cells, trouble swallowing and impaired judgment. Avoid grapefruit and grapefruit juice. Use caution before driving or operating machinery. Amy is part of little moments with the family. . And those everyday moments feel special to us. Ask your doctor if oncedaily latuda is right for you. Pay as little as a 15 copay. Visit latuda. Com mollys not thinking about cancer today, but three years from now, a routine screening will catch it early and make all the difference.

Theres an app that allows you to ekt did with people in other states and swap your votes. Is that even legal . Heres abcs terry moran with more of our series inside the final 30. Get out and vote come out and vote reporter in the home stretch of whats become a razorthin election, both campaigns are out in full force. Their message . Every vote counts. Are you going to vote . Yes, i am. Reporter a message cecil weeks has taken to heart in a surprising way. Who are you going to vote for . Jill stein. Do you support jill stein . I support hillary. Reporter cecil is putting democracys most precious gift, why are you voting for jill stein . I can help thirdparty supporters legitimize third parties by voting for their candidate in my safe blue state of new york, and they can help me out in a swing state and vote for Hillary Clinton. Good spirit and trust . Reporter its called vote swapping with the help of an app called nevertrump, cecil will vote for jill stein in new york, his swap partner says shell vote for bigger difference than i than in new york. Reporter for the race for the white house neck and neck in some states a fourpoint race reporter thirdparty candidates have the potential to sway the outcome. And so voteswapping options like never trump, trump traders. Org, and vote pact. Org, help some voters redefine how their vote counts. You dont have to worry about trump up to date. You get to have your vote somewhere else and hillary gets another vote ensuring a trump win doesnt happen. Reporter the never trump app is the brain child of Silicon Valley ceo ahmed kumar. Despite the name of the app, he says its more about the democratic process than the democratic ka ic candidate. People in deep blue or deep red states realize their votes dont matter as much. If theres a way for you to have that vote count, the participation ra activated. Reporter it might seem hard to believe, but voteswapping is actually legal. Voespairing is perfectly constitutional and legal and its heartland First Amendment expression. Reporter its not a new idea. Maryland state senator jamie ras kin proposed vote swapping in 2000 to help Green Party Candidate ralph nader get enough of the popular vote without taking votes from al gore. I was trying to figure out a way that progressives could get in return, nader could get votes in safe red states. Reporter voteswapping websites popped up but they were called into question. A number of republican secretaries of state and attorneys general sent threat letters to the operators of the websites saying that they were engaged in an illegal votebuying conspiracy. Which was ridiculous. They shut the websites down. Reporter but a lawsuit followed and finally, in 2007, it was is totally kosher, as long as no money or anything else of value trades hands. A lot of talk about how ralph nader might do reporter the socalled nader effect, when just a few votes for a thirdparty candidate can make a difference, had already happened. Lets talk about that extremely tight 2000 election and how voteswapping could have impacted the race. Bush, gore, nader. In florida only 537 votes separate al gore and george bush their vote with people in a safe blue state, al gore could have possibly won florida and then the presidency. Reporter not wanting to repeat the past has brought new jerseyen joel and Floridian Carrington together. Joel, a hillary supporter, is writing in Bernie Sanders for carrington. In turn, she votes for clinton. It seemed like it would give me a way to still allow my voice to be heard. But in a different and at the same time prevent trump from taking florida. Reporter the approach relies on the honor code and a little investigative work. I looked at joels facebook. I saw that he was a real person. I saw he had antitrump posts. He was pretty liberal. And i decided, okay, this guys the real thing, hes not going to screw me over and vote for trump. So you guys have established trust here in a nasty campaign, its actually kind of its totally legit. Its not illegal. Reporter but a lot of people died for the right to vote over the years. Right. Reporter do you feel like youre gaming this a little bit . I could see how people would take it that way. But personally, i just feel that im using my vote the way it was intended to be used. We can make history. Reporter can voteswapping really affect the outcome of the election . We have to remember its a very small percentage of the public eng voting behavior. But if the race is as tight as some polls show, voteswapping and thirdparty voters could absolutely impact this election. Reporter still, a lot of people dont know voteswapping is a thing. I dont really understand how it could possibly work. Reporter and others see it as a way just to game the system. Your vote is your vote. Thats your vote. And that should be your vote, not somebody elses vote. Reporter but if cecils any indicator, technology and i think its democracy at its best. I think its a really nice way to work things when you feel like your options are limited. If Hillary Clinton wins arizona by one vote, were going to do an interview. Im sure theres lots of people coming to see me. Reporter for nightline im terry moran in new york. Next, a trumploving family setting up a rigged system in their own front yard.

You gotta see this guy. Ahh, i dont know what i said, ahh. I dont remember. Finally tonight, how far will one family go to protect its trump signs . More of our series inside the final 30. These president ial campaigns have been throwing a lot the dirt reporter from corn country to the u. S. mexico border, abcs Michael Koenig taking the election cycle literally, cycling 1,000 miles across the country. On this new jersey pit stop, he met one family taking extreme and we went through about six of them stolen. You created a huge fence . We started with a smaller one that people were crushing with the signs in it and stealing the signs. And we installed a camera, got a couple of pictures of people. Reporter eventually they added this electrified fence. If they even touch the sign theyre going to get zapped. Reporter their son says he witnessed a thief. He stopped in front of the sign, got out of the the sign and drove away. Reporter in texas . In michigan its Hillary Clinton signs as well. I think the amount of yard signs being stolen is reflective of the amount of enthusiasm thats out there. Reporter back in new jersey what do your neighbors think of this . I spoke to one guy, a little bit of a liberal. I said we have our trump signs in a dog pen and he said, thats where they belong. Until election day.
