because i've got eight cleveland bails bondsmen on speed dial and giving serious consideration to borrowin our screens are filled with political ads. some are supposed to make us feel good. others say who the candidate supposed to be is. >> oh, i don't know what i said. >> this year, more attack ads merely by quoting the candidate. >> we will raise taxes, yes, we will. >> every year, pundits say this is the that'siest election ever. >> taking it to a new level. >> dirty is not new. founders said vicious things.

what if they'd had tvs? >> john adams is a blind, bald, crippled, toothless man who wants to start a war with france. >> makes me glad i'm not running for office. >> don't watch "stossel," he's nothing but a hack. >> which ads work? which don't? what's different this year? that's our show tonight. and now, john stossel. >> this year sets another new record for political spending. people get upset that money is such a big part of politics, but what do you expect? since government's gotten so big that it's moved into every cranny of our lives, it's no surprise people spend a lot to influence it. favors, getting hands in trillions of dollars the feds hand out.

others spend out of fear. please, if i give you campaign money, will i get access to you to lobby you so you don't regulate me out of existness? yes, $6 billion is a lot of money, but it's less than americans spend on potato chips. the election's more important than chipsin, right? i'm surprised they don't spend more. the nominees are picked. they have. don't believe the pundits saying, oh, bernie has a chance, maybe paul ryan is chosen over trump in a brokered convention. it's really dubious looking at the betting odds. here's the simplified version. it's just about certain that clinton gets the democratic nomination. trump, the republican nomination. now the political spending will increase more, and most of the money will be spent on tv ads. although, this year, you have to wonder, why do they bother because in the republican primary, donald trump's

opponents spent a ton on anti-trump ads like this one. >> why does trump support amnesty? maybe because he makes big money off immigrants, and his new hotel in washington? >> they interviewed 15 laborers, many revealing they entered the u.s. illegally. >> and big money for himself. can conservatives trust donald trump? >> i would think not, but best i can tell the ads make no difference. pacs kept running them, and trump supporters got more passionate. what's going on? well, guy benson, and our political junkies follow the campaigns closely so i don't have to. what happened this year that's different? >> well, they are playing to the base in large part. if you looked at that trump ad just now on immigration, i don't think they plays well in a general election. independents watching that would be really concerned, but when i

watch the ads of the political season, i felt they tilted to the base. it was a really rough fight on the right for that base. there's ted cruz, donald trump, they had to win them over. >> expected base went for trump anyway. >> that's true. what i said for a long time is no matter how much money you put into something, campaign ads in particular, people watch the candidate, inspired by you, and no amount of money or ad dissuades people if inspired and the rest of the field does not. >> what's different about this cycle is you're hard pressed to find a donald trump ad that ran with money behind it. he chewed the entire tradition until process and flooded air waves to attract billions worth for free. >> for being himself. >> showing up, and calling into every show. that'll happen. it's been interesting to watch. the average politician could never, ever get away with that. >> that's what happened so far. the left is marginally the

attacks on trump. one of the themes they are hoto disrespecting women. >> a good body, no, does she have a fat [ bleep ], absolutely. >> if she's not my daughter, perhaps i'd be dating her. >> that's a new ad from hillary's super pac. now it's finally going to work? >> i think it might. i think in a general election, he needs that female vote and the fact it's coming from a female candidate calling attention to the fact he's said this about women. this is the kind of ad that i think works because there is truth in terms of statements that people can say, wait a minute, this is what he remits and draw conclusions. could be effective. >> the argument it didn't work in the past because there was a republican group that put out almost the exact same ad using words against him.

it did not move plurality of the republican electorate, but votes from women have. terrible for months. i think hillary pounds away at it. >> and the odds at electionbiddingodds.com show hillary is a big favorite in the general election. >> for now. for now. >> that's true. >> yeah. >> she's really bad. he's bad too. >> bad versus bad. the trump campaign itself has not spent much on adsings but they've run a few. here's a sample. >> donald trump calls it radical islamic terrorism, calling for a temporary shut down of muslims entering the united states until we figure out what's going on. he'll cut the head off isis and take their oil and stop illegal immigration by building a wall on the southern border that mexico will pay for. >> forward, sticking to the guns, and i think the genius of

the ad is looking back how much money was poured into that ad, it was minuscule. the point of the ad was to reenforce messaging, and every single show on broadcast, cable, and radio ran the ad for free over and over again and had people like us on, panels, stroking our chins, well, what does he mean by, "until we know what's going on" whatever term he uses is, that's been the genius of the trump campaign this cycle. >> here's one anti-trump ad that i found so weird and ugly that i thought it might be something from a pro-trump group trying to make trump supporters angry they would show up to vote. let's watch. >> you keep calling me anger baby. >> ratist. >> millions of working latinos deported. >> you're all going to have to go through me. >> this is my home.

>> you can't take my rights away. >> that's from a group called deport racism with the goal to fight racism, but -- >> yeah. that rubs me the wrong way. i don't know anyone that likes watching children use vulgarity like that. i think there was a way. >> they were told to use. >> right. there's a way to make the argument that some of the policies with respect to immigration are problematic, and you could have even maybe utilized children. i don't like children in ads, but there's a way to do it. this was not the way to do it but to get everyone at home feeling uncomfortable about not only the way you utilize the kids, but them about the message in totality. ineffective in my book. >> the group didn't call us back. i wanted to ask them -- >> i can't imagine why. >> did it work? >> who are these people? these are children reading scripted lines written by adults for them to come out and, like, all right, you know, johnny, let's take that again. if you can just say this curse word a little bit more angerly. it's so distasteful.

>> yeah. let's look at a democrats' ads. one hillary ran before hawaii. >> i believe in building ladders of opportunity for people. >> here in hawaii, nothing matters more than the education we provide for the next generation. that's why hillariments preschool for every child. >> preschool, every child, both bernie and hillary, just free stuff, here you go. >> yeah. i think it sounds good. i think, for me, i mean, she's unlikable in my book, so anything that takes attention away from her to other things getting on. >> free stuff. >> right. you don't have to explain how you're going to do it, right, in a campaign ad, tossing out the idea of free, and people at home say, oh, that's great. there's no explanation as to how or implications who pays for it. in that way, it is effective. >> i don't get the southern accent. >> that brings on another occasion. >> it's hawaii. >> what surprised pundits was trump's success with

conservatives, even after opponents pointed out trump said non-conservative things. the ads made it clear that his opponents were not lying about it. they ran trump in his own words. >> everybody's got to be covered. this is an unrepublican thing for me to say. >> universal health care. >> i'm going to take care of everybody. >> who pays for it. >> the government pays for it. >> i hate the concept of guns. i'm not in favor for it. >> i'm very pro-choice. >> i would have thought conservatives hearing that would turn away from trump. that's not happened. to help understand why, let's turn to someone who's spent years doing experiments to see which ads work, which don't. adam schaffer. why did trump do well? >> well, i mean, a lot of the negatives were built in early on. people know him well. it's difficult to introduce new

information that's negative about him, frankly. >> a lot of people love him and vote for him in the primary. >> they do. i think other things outweighed the negatives, and the negatives they focused on are things already built in. >> all right. you test ads to try to figure out what will work. >> right. >> explain. >> well, we test ads the same way you test pharmaceutical drugs, randomized control trial. people come into a survey, some see a sugar commercial with no political content and others see a political ad. we compare the results in the treatment of the control group. >> you found odd things. it's hard to change people's opinions. >> well, i would put it more -- people's opinions shift all the time. it's hard to find what moves particular people. not everyone's the same, not every ad's going to work. hard to predict in advance what is. >> talk about the budweiser ad.

>> we tested beer ads, one from the super bowl, bud attacking microbrews, fussy ales. >> before you say more. let's play most of the ad that he showed to his group of people. ♪ >> let the craft brewe eers do pumpkin ale. what's the surprise? >> it really helped trump with women. >> just threw in a political question for the heck of it, and maybe 8% change an opinion if it's a great ads. in this case, 18% of women?

>> all the impact concentrated among republican women, and he started out at a low level to begin with on them. >> after they saw that ad -- >> yep. it bumped from 60 to 78%. >> another group saw the ad from the craft brewery that was -- >> yeah. that didn't change things nearly the same way. so, you know, i think it's -- as you pointed out, if he, you know, craft brew drinking men versus the manly men, and, you know, what's stereotypes do they sound like in terms of parties, so, i think, you know, this indicates to me the female vote is volatile this year, prime to moved back to trump. >> how much do campaigns pay you? to give advice. >> not enough. >> 5% of what you spend? >> no, no, no. you know, one of the things in politics, i think, is far too little testing is done, especially on the republican kind of conservative side.

this is much more extensive and common on the left. >> that's interesting. when you pay to test subjects? >> sometimes, it depends. sometimes are, usually if it's a panel where you want to get them to respond to further surveys, you need to give incentives to keep them interested. >> later in the show, we're going to show old ads like morning in america, pundits say changed people's opinions, but, today, are these happy ads as effective as negative ones? >> well, we have not tested very many of them. percentage of the ads, there's a lot more negative ones out there. you know, there's a lot of information in negative ads. they deliver information to people. people are more attentive to negative information. that's a fact of life. >> more likely to change someone's mind. thank you, adam. to join the argument, please, follow us on twitter, john stossel, or "like" my facebook page and post on my wall. coming up, all kinds of nasty

attack ads. >> don't watch stossel, he's nothing but a hack, a corporate show. >> this show has been approved by the mainstream media. ♪ [announcer] is it a force of nature? or a sales event? the summer of audi sales event is here. get up to a $5,000 bonus on select audi models.

let's of specialists say to change voters's minds is negative ads. that's probably why we see so many now. he's an anti-trump ad from a group i like. >> which presidential candidate supports higher taxes, national health care, and the bailout? it's donald trump. >> in many cases, i identify more as a democrat. >> they want us to think he's mr. tell it like it is, but he has a record, and it's very liberal. he's really just playing us for chumps. trump, just another politician. >> in many cases, i probably identify more as a democrat. >> despite ads leek that, donald trump crushed other republicans, so every group that runs ads is trying to figure it out. how can we make our ads more effective?

the advocacy group, freedom works, pays for ads that support some candidates and attack others. how do you vet these ads? what makes you think any of them work? >> well, this last cycle, most of the ads that we have run have all been positive, and the goal of the ad has been to raise up awareness of the candidate. people like thomas from kentucky, he's new, a lot of folks didn't know who he was, so when there was not a lot of other political chatter, you could run an ad promoting what he was doing, and it raised his awareness, and that was the goal of what we were trying to do in the ads. >> how do you know it works? >> maybe -- the reason we think it works is because we heard rumors the chamber of commerce was putting up $2 million, and the ads were in, and approval ratings went up, and there's no opponent in the cycle.

>> he's kind of libertarian. >> why would the chamber attack the libertarian against xm bank and taking a stand against corporate cronyism. >> another anti-trump ad. >> now the poor guy, oh, i don't know what i said, oh, i don't remember. >> if you're to morning a reporter with a disability -- >> like, i don't remember, oh, maybe that's what i said. >> trump says he was not mocking the reporter because he didn't know what the reporter looked like, but in truth, they had known each other personally for years. >> he's, like, i don't remember, maybe that's what i said. >> seems like a very damning ad, but doesn't have any effect. makes you wonder why anybody buys ads. >> right. i believe that ad in particular the reason it didn't land a blow because trump is seen as an ultimate outsider so when he's attacked by someone like john

kasich for attacking the media, people are, like, i don't like the media. it was not about makie infun ofe person's disability, but we want trump because he's an outsider, and so he makes fun of the media sometimes, so what. >> so the way to win is to hate the media. it's a little creepy for me. here's an ad from a republican pac attacking hillary clinton. >> i think i'm probably the most transparent person in public life. i feel, you know, a lot more about me than anybody else. i'm the most transparent person in public life. stay tuned, there's a lot more. >> hillary supporters say, oh, you right wingers gone after her. it's just nothing there. >> goal of an ad is to bring up positives of your candidate and demoralize your opponent. when i hear that ad, what i'm thinking is republicans probably

look at hillary clinton being, like, yeah, this woman's been a scamble-written politician since her days in arkansas, and democrats that support her, it just glances off because they don't believe she's a scandal written politician. >> why run the ad? you have to reach the democrats. >> of the reasons you run ads is that the main way a lot of people make money is taking a cut off of ads, and if you plolook at the e of donald trump, the media he gets is just the $2 billion in free earned media. i think if you look at bernie sanders, i don't think his rise has been from the television ads he's been running. it's been because he's connecting with progressive grassroots, and if television ads were going to make the ultimate difference, jeb bush in his $120 million would have been the republican front runner. >> right. >> and hillary spent more, by the way. thank you, adam. next, why does this ad feature hillary clinton barking?

donald trump's beaten all the career politicians, and he doesn't even run tv ads. actually, he's run a few. most trump ads are short, cheaply produced ones like this. ♪ >> why was hillary barking, and is that a good ad? the man who bloomberg news service says invented the republican internet says trump's strategy is the way of the future. he's vincent harris, what do you mean? way of the future? >> well, i think that donald trump's campaign gets better than any other campaign in the history of american politics

today's fragmented media environment. voters consume news and information not just by watching tv, but they go home for tv, screen one, laptop, screen two, and phone in the hand is screen three. he understands screen two and three are places to reach voters, and that ad we saw was a wonderful example of that. that ad is the exact type of ad people share, and my friends on facebook pass along and see it. >> and it's short, and facebook people stopwat watching after -- >> after 22 seconds according to a recent study. if an ad is longer than 22 seconds, people are going to discard it and move on to a sports score or cat's gif. >> a candidate who flopped but should have won, senator rand paul, showing this ad, setting the tax code on fire, putting it through a woodchiper, this, too,

different. >> that was senator paul's idea. >> he took that from me. i duke a buzz saw to the budget. >> great minds, john. we didn't have a lot of money, but wanted to produce something that people would naturally share online, and this was one of the most successful ads in terms of organic views. >> one more successful, do other candidates ran bizarre ads this year. was this one from ted cruz talking about machine gun bacon. ♪ >> a few things i enjoy more, weekends, cooking breakfast with the family. of course, in texas, we cook bacon a little differently than most folks. ♪ >> machine gun bacon? yes. he wrapped bacon around the muzzle and cooked the bacon by shooting the gun, and then he ate the bacon.

>> machine gun bacon. >> i think he seems weird. this is effective? >> yes. in terms of getting reach when voters can just simply click stop on an ad online, so i think he really understands by producing that ad that if an ad's not entertaining, a voter's not going to watch it. >> and donald trump certainly gets that, and he saves himself so much money running a new kind of campaign using the newest technologies, instagram, twitter. he sends out all nasty tweets. listen to carly fiorina more than ten minutes you develop a massive headache. complaining about mexico, we get the killers, drugs, and crime, they get the money. doesn't cost him anything, and this, too, goes viral. >> donald trump has 8 million followers on twitter, which is a larger audience than most television networks, and there was a recent study done by political scientists that showed entertainment media can prime

voters to believe something that a candidate is going to say later down the line. he gets this, and that's why he's won this primary. >> but probably his that'siest tweet was the one that showed pictures of his wife and ted cruz's wife, a glamorous picture of trump's wise, cruz's wife unflattering pose, and trump did not compos the tweet, but a capture of a picture is worth a thousand words, but he retweeted it, which is just as mean. >> so, look, i don't work for trump, i can't comment, but he's generating engagement and breaking through a very cluttered news environment. that's what he understands. he's really used his celebrity to go out there into social media on to online, and reach voters individually, and that's exactly what he's done in all of the states. >> that's what you say the future is not so much sadly what pays me, tv in general, but specific stuff reaching specific

voters. >> yes, sir. every ad online could be targeted to an individual. facebook allows you to go and take an ad and run it against the voter file. >> i hate it. we're out of time. thank you, vincent. coming up, this year's best and worst ads, and ads that change elections in the past. >> some places give you a lot less beef on a lot of bun. >> where's the beef? okay, so what's our latest data say? our customer is a 21-year-old female. heavily into basketball. wait. data just changed... now she's into disc sports. ah, no she's not. since when? since now. she's into tai chi. she found disc sports too stressful. hold on. let me ask you this... what's she gonna like six months from now? who do we have on aerial karate? steve. steve. steve. and alexis. uh, no. just steve. just steve. just steve. live business, powered by sap. when you run live, you run simple.

can political ads make a big difference? we've seen how ineffective they've been against trump. how jeb bush spent more on ads than any other republican, but still lost. however, political ads can change campaigns, and they have. i did a fox special on campaigns

monarchy? >> if thomas jefferson wins, murder, robbery, rape, adultery, and incest will be openly taught and practiced. are you prepared to see your dwellings in flames, female chastity violated, children riving in a pike? >> makes donald trump seem gentle. >> she came to my wedding, ate like a pig, does she have a fat ass? absolutely. there was blood coming out of her eyes or wherever. >> not gentle, but no worse than andrew jackson supporters who said, among other things, john adams was pumping out his maid to the czar of russia. 136 years later when barry goldwater ran against johnson, johnson supporters said goldwater was a schizophrenic, a magazine called fact got a thousand sigh sigh trysts to sign a statement saying goldwater was insane.

none of it was true, and he won a suit against the magazine, but by then, the election was over. the smear helped president johnson win a big victory. every election year, some candidates say, i'm tired of those ads that are filled with attacks and negative campaigning. i'm going to run a positive campaign. john kasich said that as well as bernie sanders. >> i've known her for 25 years, i'm not running personal attacks against her. >> but as he fell behind and hillary said sanders was not qualified, sandered attacked her saying she's not qualified. >> i don't think that you are qualified if you get $15 million from wall street through your super pac. i don't think you are qualified if you have voted for the disastrous war in iraq.

>> candidates say they'll run a positive campaign, part of my brain says that would be nice. maybe we'd learn more that way, but the research actually shows that's not true. it's especially not true for those feel-good ads. ♪ >> singing all come to look for america while bernie sanders shakes hands. warm and fuzzy. what's it mean? did they find america? the beauty of the negative ads is that most present what they claim are facts, even if the accusations are lies, those lies force the other side to reply with fact, so voters actually migh some of the attack ads are deceitful, but, usually, eventually, the truth comes out. so three cheers for negative ads. good comes out of the bad. the ads may be disgusting, but the truth often is. that's our show.

see you next week. >> a shooting in dallas left five officers dead and two wounds. >> the video went viral showing officers killing black men in louisiana and minnesota. >> the officer just shot number his arm. >> to learn what really happens during confrontations like that, we used to have to rely on eyewitness accounts. but now video changes everything. sometimes it reveals bad police, sometimes bad poli.
