>> tomorrow's venezuelan presidential election could be the most consequential in nearly a decade. experts say nothing less than the future of venezuelan democracy could be at stake. the nations increasingly authoritarian president maduro is looking to extend his time in the office he assumed in 2013. >> if you don't want venezuela to fall into bloodshed, let's guarantee the biggest electoral success in the history of our people. >> polls show him trailing his challenger edmundo gonzales urr utia by a large margin. a coalition of opposition parties picked him as candidate. >> i want to call on all venezuelans to join me in a peaceful orderly change of government. >> he has the backing of the driving force behind the opposition after winning a

primary with more than 90% of the vote, the maduro government banned her from running. >> this moment we are living in is the closing of a cycle of chaos, to begin an era of order, stability, and a security. >> together they have energized voters by promising to reestablish democratic institutions and into the economic and human rights crises that have led more than 7 million venezuelans to leave the country over the past 10 years. many sought refuge in neighboring colombia and brazil. last year, u.s. authorities encounter tens of thousands of venezuelans along the southern border. if the polls hold true and maduro loses some analysts are skeptical he would accept defeat and give up power. an associate for the center of strategic and international studies and a former deputy mayor of one of the five municipalities in caracas.

why is this election so important and why are people watchi it so closely? >> the expectations for tomorrow's election are astronomical because there is so much at stake, human rights, liberty, democracy, freedom of association. i think the most important thing on the ballot tomorw is the reunification of many venezuelan families who had to be separated because of migration. there are over 7 million migrants from venezuela already across the world. people are going to t ballot box tomorrow to bring back the brothers, sisters, parents, and kids. what venezuelans were the most is to be back together as a family in a democratic, progressive nation. >> i have read reports of the rallies that maria corina machado was holding that she has to sneak in. what is creating this enthusiasm? >> this time there is an opposition unified under maria corina machado the opposition

leaders and our candidate urrutia. people want tomorrow to make a change and have their voices heard. they are tired of hyperinflation and food scarcity. they are tired of n having water or electricity and they are tired of political persecution. people want to change and that is what that's why there is so much excitement tomorrow. >> late last year the maduro government and opposition signed an agreement to reinstate some democratic institutions and pave the way for free and fair elections tomorrow. what happened to that agreement? >> there have been no free and fair elections. maria corina machado was chosen in the primaries and maduro did not let her run. she appointed a successor to run and they did not let her run. after negotiations it was edmundo gonzales urrutia. almost 8 million migrants are outside of the country.

the regime did not allow them to register to vote for your 4 million people from the diaspora can't vote. these are not free and fair elections. >> will there be international observers tomorrow? >> there are a couple. but if you saw yesterday, the maduro regime gave orders to deport the different ex-president from mexico, from bolivia, from panama. senators from the european union and columbia. people that were going to travel to venezuela. maduro's regime command was, make sure they don't get off the plane or don't but the plane kick off because they don't want the international community to see they will lose tomorrow. >> with the skepticism of weather maduro will acknowledge defeat what are the range of responses we could see come monday morning? >> he has shown no indication of wanting to admit defeat, but it is hard to say he won't if

the polls are giving his opposition a 25-30 point advantage. it will be hard to convince the international community he won. >> i have seen it said that there may have to be negotiations between maduro and the opposition. or, the victors in the election for him to actually leave office. what are the topics of those? >> anything the international community or opposition community could do to create incentives for them to go after they lose are always positive. after the election there will be a six-month period of transition where we hope the regime allows peaceful, orderly transition to reach democracy when they are sworn into the presidency. there will be conversations. what is clear is the opposition will probably win torrow. >> the u.s. and venezuela have not had diplomatic relations

since 2019. what are the implication for the u.s. in this election? >> migration is on the ballot. if we want people to stop fleeing from this country and all of the disaster we need to stop maduro. i think there is a direct correlation with the election. if we don't bring venezuela's prosperity and democracy back we will see that migration uptick quickly. >> alexandra winkler, thank you very much. >> thank you. >> during three years of stubborn inflation, many american households cut back on routine purchases at the store. amid assigns retail prices have started to drop, some companies are rethinking how they decide what to charge. more on the new technology that allows retailers to quickly change prices for items on shelves. >> the traditional prices we all

see on grocery shelves may be on their way out in favor of digital or electronic shelf labels with small digital screens where prices can be updated remotely, sometimes daily. consumer advocates worried the technology could lead tosurge pricing already seen with concerts, travel, and ridesharing. walmart announced that by 2026 more than 2000 stores would have digitized shelf labels. an e-commerce and retail reporter at reuters. thank you for joining us. how does a digital shelf labels work? how common are they in the u.s. right now? >> the digital shelf labels are small digital screens that reflect prices. generally, they use google

technology to communicate with mobile technology to update the prices very quickly. so far, the adoption of it in the u.s. is not as rampant. certainly, walmart is one of the companies that has gone big introducing them in their stores. we also know that kroger and instacart are testing it now. but we have not seen it in stores yet. me and you, the regular customer want to see it in the next two or three years unless you shop regularly at walmart. >> the technology is prevalent in parts of europe right now. i want to ask about what retailers say about the benefits of electric store labels and how the benefits might end up trickling down to customers. >> from the walmart perspective, when they introduced this they were speaking about how they could label prices more easily.

what would take a week for a worker wilnot a statement of -- will now just take minutes. it will replace eco-shelf labels, cutting back on paper waste by 20%. they said it is an easy technology for them to keep associates abreast of the inventory. and, if they want to use it to let know -- let workers know how to pick up products for online workers. so they can figure out where in the store the product is. there are multiple ways they can use the technology. in fact, sometimes, retailers are using it for displaying qr codes. so if you buy heinz ketchup, you do not know if it is gluten or allergen free. or the fat contained in it. these things are displayed on the label easily. but you can get a scanned qr

code right on the shelf label. you can whip out your phone and see the information easily. that is another aspect of for digital shelf labels are being used to help the customer. >> i know walmart and other stores are arguing those efficiencies could lead to savings for the customer. i want west about the flip side, consumers and advocates are nervous that there may be dynamic pricing employed in which retailers increase prices of items based on demand. how are companies responding? what is the likelihood that sort of practice will take place? >> dynamic pricing is generally legal in the u.s.. any retailer is able to do it if they want. but, because of the backlash against surge pricing, walmart won't be using it for surge pricing. if they use that it will be to cut prices or offer promotions or display promotions or discounts. for consumer advocates there is

concerned they could raise prices. this has happened in the past. coca-cola in the 1990's had a vending machine where they would raise prices when the weather was hot. that created backlash and they quit that program. surge pricing in grocery stores, it would be hard for retailers to get away with it. why are the efforts being employed now? they have been the norm in europe and parts of the u.s. for a while now. is it just the pace of modernization, or, are these efforts by retailers to address inflation concerns or a combination of the two? >> retailers are trying to upgrade their stores using automation. they are trying to u materials like led. now they are moving towards digital shelf labels. one part of this is modernization. it helps with efficiency. if they get digital price labels

they can update prices to market conditions more easily and there will not be a lag between what the market says and what you can put in the store. it helps with managing inventory much better. when you want to sell products more quickly, think about a milk carton that expires in two days. you want it out quickly. then it may be you cut the price by half so people buy it more quickly. there are ways to address bringing inflationary pressures down on their business and also reducing cost. i mentioned earlier that the paper shelf tags were a big environmental issuand cost problem. replacing paper shelf tags with digital shelf tags they can reinvest savings back into price. >> thank you for breaking this down with us. >> thank you for having me.

>> in about two weeks at the paris olympics the debut of an entirely new metal event, breaking, what is more widely known to the uninitiated like me as breakdancing. in a los angeles dance studio, 20 one-year-old logan teaches moves she spent years of her life developing since she was just seven. she is one of the four members of the u.s. breaking teams at the paris games. she is an olympian. >> i see any title, championship, or win for me to amplify any message i want. i represent having fun and being a student of that game and caring about the evolution of where it's going. keeping it alive. >> the first olympic breaking competition without -- was at

the 2018 youth game in one of sarah's. -- buenos aires. competitors draw disciplines like martial arts and gymnastics. it was created in the 1970's at south bronx dance parties by black and latino youth. it says the name comes from the brakes on hip-hop songs when the vocals dropped leaving a steady driving beat. the 1983 film flashdance helped breaking go mainstream with a scene from members of the hip-hop group rock steady crew. now it's popularity is global. from the united kingdom to france. >> you think about paris. maybe you think about the eiffel tower. but, when i think about paris, i think about hip-hop. >> nigeria.

egypt. >> dancing is what makes you stay away from smoking and drinking and all of the self-destructive things. for me, it is an art and also i something -- also it is something i find myself in. >> brazil, libya, even iran. >> ine love to dance as other people do. we love to enjoy our youth. >> what was born at block parties in the bronx will be going for the gold in the heart of paris. an actor, tv host and accomplished dancer and choreographer has been a judge at olympic qualifying events for breaking. help this baby boomer. breaking or breakdancing? >> well, we call it breaking. if you accidentally call it breakdancing, we will let you

slide. it's more of a media term that came out in the early 80's. i understand why people call it breakdancing, because they are breaking and it is a dance but we call it breaking. >> what is the significant of having this as an olympic event? >> in 2018 we got the first indication we could hit the main stage and breaking is finally where it needs to be going for gold. >> is it a dance style? a culture? >> for me it is like a religion. you have to believe in yourself and your talent and go above and beyond the call of duty just to be recognized. a lot of the breakers, whether they have jobs 9-5, whether they have school, what age they are, they are putting in endless hours. breaking is not just a culture and a phenomenon, but anrt and sport and the fusion of that is

what people will see in paris. it's like haley's comet. you have to catch it while you can. >> you won't be judging in paris, but you have judged some qualifying events. how do you judge this? >> there are a couple criteria and boxes they have to take. it is technique. how good you are at doing everything you have been training to do. you have to put years in the game. your vocabulary. your vocabulary that you bring to the table. a-z, freezes, power, footwear, combinations and how many times you can switch things out. originality. you want to be the one and only. to do that you have tstand alone. you have to be unique and show as many original moves as you have learned in the past. you only have 60 seconds before

your opponent answers back. you want to execute from the very first second you stand on the floor until the end of the 59.9 seconds when you are walking off. also musicality. i love musicality. i will tell you why. we are dancers. so, it is all framed around the music. if you don't have musicality and you are dancing with either two left feet or you are off beat we will ding you for that. you have to marry the music that the djs are playing. if you don't know the bpm or the lyrics to the track. it's a cool game of cat and mouse. >> tell us about team usa. >> you have victor montalvo from florida, the highest rank in the

entire world. we have logistics that i met years ago. i worked with her on a nickelodeon show. a few years later she was on world of dance and now she is on the world's biggest stage in the olympics. the -- b-boy jethro, his musicality is on point. it will be a nailbiting couple days. >> what you see as the future of this? where do you want to see it go? >> with that news, sadly it wasn't accepted for 2028. what better way to bring it back to the u.s. when it all started? hopefully it is in brisbane in 2032. i am praying for that because

you don't want too much time to go by. as the dancers are getting older they are evolving. the future looks bright for breaking and you may not see the same competitors in the next cycle. i want breaking to stay on the roster. it survived 50 years. whether it was in the media or in movies or underground culture of our -- culture or subculture it survived. it is definitely ready to earn a permanent spot. >> flips, thank you so much. >> thank you so much for having me. i am excited. >> that is pbs news week and for this saturday. 'm john yang. for all my colleagues, thank you for joining us.

see you tomorrow. >> major funding for pbs news weekend has been provided by. and, with the ongoing support of these individuals and institutions. this program was made possible by the corporation for public broadcasting and contributions to your pbs station from viewers like you. thank you.
