? it's difficult to see someone you love struggle. i miss out on life's 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, once-a-day latuda was proven effective for many people struggling with bipolar depression. latuda is not for everyone. or suicidal thoughts. 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 life-threatening 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 once-daily latuda is right for you. pay as little as a $15 copay.

what greases the gears in washington? money. and ron johnson fits right in. six years ago, johnson took a shady $10 million corporate payout, went to washington, then voted to protect $21 billion in tax breaks for the world's biggest oil companies.

his vote, in the hands of a complete stranger. >> why are you voting for jill stein? >> i can help third-party 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: it's called vote swapping with the help of an app called #nevertrump, cecil will vote for jill stein in new york, his swap partner say vote for clinton in arizona. >> i feel like i'm making a bigger difference than i than in new york. >> reporter: for the race for the white house neck and neck in some states -- >> a four-point race -- >> reporter: third-party candidates have the potential to sway the outcome. and so vote-swapping options like never trump, trump traders.org, and vote pact.org, help some voters redefine how their vote counts. >> you don't have to worry about

vote in a swing state could make trump up to date. you get to have your vote somewhere else and hillary gets another vote ensuring a trump win doesn't happen. >> reporter: the never trump app is the brain child of silicon valley ceo ahmed kumar. despite the name of the app, he says it's more about the democratic process than the democratic ic candidate. >> people in deep blue or deep red states realize their votes don't matter as much. if there's a way for you to have that vote participation rate, the citizenship, will be more activated. >> reporter: it might seem hard to believe, but vote-swapping is actually legal. >> voes-pairing is perfectly constitutional and legal and it's heartland first amendment expression. >> reporter: it's 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

votes where he needed them, but in return, nader could get votes in safe red states. >> reporter: vote-swapping 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 vote-buying conspiracy. which was ridiculous. they shut the websites down. >> reporter: but a lawsuit followed and finally, in it was decided that vote-trading 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 so-called nader effect, when just a few votes for a third-party candidate can make a difference, had already happened. >> let's talk about that extremely tight 2000 election and how vote-swapping could have impacted the race. bush, gore, nader. in florida only 537 votes

in the state of florida. if those 537 voters swapped 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 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 joel's facebook. i saw that he was a real person. i saw he had anti-trump posts. he was pretty liberal. and i decided, okay, this guy's the real thing, he's not going to screw me over and vote for trump. >> so you guys have established trust here in a nasty campaign,

system. >> it's totally legit. it's not illegal. >> reporter: but a lot of people died for the right to vote over the years. >> right. >> reporter: do you feel like you're gaming this a little bit? >> i could see how people would take it that way. but personally, i just feel that i'm using my vote the way it was intended to be used. >> we can make history. >> reporter: can vote-swapping really affect the outcome of the election? >> we have to remember it's a very small public engaged in this kind of voting behavior. but if the race is as tight as some polls show, vote-swapping and third-party voters could absolutely impact this election. >> reporter: still, a lot of people don't know vote-swapping is a thing. >> i don't 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. that's your vote. and that should be your vote, not somebody else's vote. >> reporter: but if cecil's any

democracy will likely only continue to collide. >> i think it's democracy at its best. i think it's a really nice way to work things when you feel like your options are limited. >> if hillary clinton wins arizona by one vote, we're going to do an interview. >> i'm sure there's lots of people coming to see me. >> reporter: for "nightline" i'm terry moran in new york. next, a trump-loving family setting up a rigged system in their own front yard. their trump signs. ? my hero zero. ? ? such a funny little hero ? ? but till you came along ? ? we counted on our fingers and toes ? ? now you're here to stay ? ? and nobody really knows... ? zero really can be a hero. get zero down, zero deposit, zero due at signing, and zero first month's payment...

sign. >> it started out with one sign. 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 they're 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 -- it's hillary clinton signs as well. >> i think the amount of yard signs being stolen is reflective of the amount of enthusiasm that's 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, that's where they belong.
