march for dia de los muertos takes on additional meaning ahead of the election. what walkers are asking of both presidential candidates on the issue of immigration. good afternoon, i'm kristen z. thanks for joining us. but first, let's

talk about the rain because it is on the way. so checking in with abc seven news weather anchor spencer christian with your accuweather forecast. >> well, here's a look at the weather coming our way on this first day of november. satellite radar composite image shows some rainfall just moving into northernmost part of the state right now. will be moving into the northernmost part of the bay area later this afternoon. as we move along and take a look at current conditions, you can see well, you can't really see much right now from mount tam, from sutro tower, because the clouds are getting thicker. but it's 58 degrees here in the city. we have low to mid 60s at oakland, hayward, san jose, redwood city, 59 and 54 at half moon bay. now you can see this view from mount tam looking out over the bay and over san francisco. we have clouds at various levels of the atmosphere this afternoon, mid 50s right now, in fact mid to upper 50s at santa rosa, petaluma and napa. low to mid 60s at fairfield, concord and livermore. these are our forecast headlines today. rain arrives late afternoon into the evening hours, which means it's

going to be wet for much of the evening commute. tomorrow. we'll see rain lingering into the morning hours, but becoming drier and breezy in the afternoon, and then sunday through early next week. windy, warmer, drier, increasing fire danger for this afternoon. excuse me for this. i'm losing my voice for this afternoon. look for high temperatures around 60 degrees along the coast. we'll see mid 60s right around the bay shoreline and mid to upper 60s in our inland communities. here's the exclusive abc seven storm impact scale. you can see that the approaching storm is a level one storm. that means a storm of light intensity. so for late today and tomorrow morning, we can expect rain that will produce brief downpours at times. so that could complicate the evening commute once again. rainfall totals will range from about 2/10 of an inch to a half inch, and winds will be gusty at times up to about 35mph. forecast animation starting at 4 p.m. shows the rain sweeping down through the north bay in the late afternoon and early evening hours, and then south of

the golden gate and eastward, so all parts of the bay area will be wet after about 7 p.m. or so, and then the system sweeps on through during the very early morning hours between let's say, 5 a.m. and 7 a.m. we'll see the rainfall breaking up into just little pockets of isolated showers, and then it will be all over once again, rainfall totals will generally range from about 2/10 of an inch to a half inch, and here is the accuweather seven day forecast. so we get a little bit of arying out tomorrow afternoon before we get into sunday when it will be much drier, it will be windy, it will be warmer and that's where we have the fire. the high fire danger concerns also set your clocks back before sunday morning, as we fall back to standard time and going through most of next week, including election day, we can expect mainly sunny days, mild dry conditions with high temperatures in an almost spring like uh- range from low 70s to mid 70s. >> all right. it is the final sprint now to election day with

just four days of campaigning remaining. both vice president kamala harris and former president donald trump are taking their campaigns to the heartland, trying to win over the precious few undecided voters in battleground states. harris is scheduled to attend a get out the vote community event in appleton, wisconsin, before holding a rally tonight in milwaukee headlined by cardi b. trump visited dearborn, michigan, earlier today ahead of a rally in warren and later, he'll also hold a rally in milwaukee today. undocumented migrant families and their allies held a day of the dead, or dia de los muertos, marched through san francisco. the primarily mexican holiday honors ancestors who have passed but they're also using the moment to send a strong message to the presidential candidates. abc seven news reporter lena howland has the story. >> with election day only days away, day of the dead looks a little different. this year, with white crosses in hand. migrants are marching through san francisco, honoring loved

ones that have passed away without being visited by family. while living undocumented in the u.s. they're also honoring migrants who have died trying to cross the border. >> the undocumented community has had enough. they can't visit their loved ones in their home countries, including their children and their elderly parents who are dying simply because of their immigration status. >> rene saucedo is the organizer. she says this march is meant to send a bigger message to both presidential candidates, but it will soon be an occupied country no longer. >> november 5th, 2024 will be liberation day in america liberation day. >> this comes as former president trump continues to use anti-immigration rhetoric while promising mass deportations. on his first day in office, if elected. >> how dare he? when our families support many industries of our economy, when our

community contributes socially, culturally, economically? >> gabriela hernandez is here from santa rosa. she brought her bundled up six month old daughter to the march for the sake of her future. >> i feel so sad because we're here working. we pay taxes. we have our kids here and that is a really, really awful idea. >> on the other side, this group is urging kamala harris that if elected, her first 100 days in office must include passing legislation which provides a path to citizenship. they'd like to see this happen through the registry process. >> we're here and we're not going to stop. yeah, we're not going to stop because i have my baby here, and we are here because we have our families and we don't want deportations. yea, we want the registry bill. >> we also reached out to the san francisco republican party for comment on today's march,

and on president trump's comments surrounding mass deportations. we haven't heard back yet. in san francisco. lena howland abc seven news. >> since immigration has emerged as one of the top issues, certainly one of the most talked about in this election, we want to go beyond the rhetoric and try to understand the multifaceted impact of undocumented immigrants in this country. joining us live now is tomas jimenez, stanford sociology professor and co-director of the stanford institute for advancing just societies. professor jimenez, nice to have you with us today. >> great to be with you. >> so immigration as an election issue is certainly not new, at least a century old, right? during which time we've had bans, we've had quotas. but focus on it seems to have really been peaking the last few election cycles. why is that? i mean, is the pace of border crossings increasing dramatically? why do you think it's, you know, the focus? >> well, it's a big deal that it is a big deal. as you pointed out, uh- immigration has not been a huge focus of election

year politics. and it was really 2016 when donald trump introduced the topic as something that's prominent. now, part of what people are reacting to is certainly the change in immigration patterns in the last 30 years, people going to new locations that had not previously seen large numbers of immigrants in the u.s. south and in the midwest. but immigration is really an issue that is top of mind for voters when politicians make it top of mind. and that's what trump has done in the last three elections, but has the pace of border crossings actually increased dramatically in the last few years? >> and i guess, i mean, because even the democratic candidates will talk about the need to have reform right? >> yeah. no, they certainly have. under the biden administration, border crossings are, say, encounters with border patrol have increased. but in the last year they've actually come down fairly significantly, in fact, to levels that we haven't seen since before the trump administration under the

obama administration, border encounters were at their lowest in in five decades. so there have been enormous fluctuations, and we've seen pretty big fluctuations even in the last three years. >> all right. i don't think this is a political position to say that. i think most people intuitively understand that there does need to be rules. there does need to be a system in place that it can't be uncontrolled. but i want to get to i don't want to talk about the presidential candidates right now, their policies. i want to focus on the supposition that's out there in the discourse. right. that somehow migrants, especially illegal ones, really pose a risk. and detriment to our society. so i want to get your insight based on research, on some of the most common conceptions. is that all right? can i ask you about some of these issues? okay. public safety impact. if you look at the ads, you know that, you know, undocumented immigrants are often linked to crime in the ads, and that is the discussion. are they more likely to commit crimes than u.s. citizens? >> no. in fact, the most rigorous research suggests that they're far less likely to commit crimes. when you think about people, especially those who are undocumented, who want

to kind of fly under the radar, there are people who are extra vigilant about their behavior because they don't want to raise the attention of, particularly law enforcement. and so in places that have larger undocumented populations, you actually have lower crime rates. and in fact, we had a massive crime decline in the united states going from the early 1990s up until now. we saw an increase in the last few years, but then it's come back down again. but the overall trend has been down. there are a number of reasons for that, and many social scientists think that one of the reasons is that there's been a growth in the immigrant population and that immigrants are by and large, more law abiding than u.s. born people. >> all right. what about economic impact? you heard in that piece that my colleague did before me that some of the immigrants are saying, hey, we pay our taxes, right? but overall, are they a drain on our resources? for example, requiring social services? are they taking away jobs that otherwise perhaps would have

gone to citizens? >> it's complicated. so on net, if you look at the american economy, uh- immigrants have a slightly positive effect on the u.s. economy, but we have a multi-trillion dollar economy in some localities, especially where you have immigrants who lack formal schooling, there is a significant cost to local resources. but those costs. studies show, tend to be made up as the lifespan of the immigrants go on, and especially in subsequent generations. a lot of those studies are fairly limited in scope in that they test the economic impact of an individual or a set of individuals, without considering how it affects the broader economy. so immigrants who come here, whether they're documented or not, they're consumers, they pay taxes through sales tax. they pay taxes the same way that most americans pay taxes in april. they file their taxes. they create economic activity.

they create jobs for teachers, for in the retail sector, for people who sell cars. and so one way to think about this is what happens when lots of immigrants go away suddenly. and then we think of that as kind of a natural experiment. and that has happened in a number of instances, often through mass deportation. and what you see is an economic collapse, especially in small communities that have seen mass deportations. and i can think of examples in, in, in the midwest and in the south, both of those under the obama administration. >> all right, professor jimenez, just real quickly, let me just ask our producer if our next guest is in. >> they are. okay. that is all the time we have for stanford sociology professor tomas jimenez. thank you so much. really appreciate the conversation. >> it was a pleasure. thanks for the opportunity. >> we'll take a sh

of the popular will than traditional voting. that's because it is the system san francisco voters will use to choose their mayor. it is also the system that produced the oakland mayor, who is now facing a recall. so we want to offer some tips on how to fill out a ranked choice voting ballot to reflect the fullness of your preferences and to look at its pros and cons. joining us live now to offer guidance, jason mcdaniel, associate professor of political science at san francisco state university. professor mcdaniel, thanks for your time. >> thanks for having me. >> correct me if i'm wrong, but i think about 45 u.s. cities currently use ranked choice voting right, including san francisco, oakland, and berkeley. >> that's about right. okay, yeah, that's about right. >> okay. based on your research, what are the benefits of ranked choice voting versus the traditional pick one approach?

that is, what is the reason that some of these cities switched to it? >> well, the idea in theory is that a rank choice voting election can allow a full majority to vote because we can rank all the candidates and we don't have to waste our votes on, quote unquote, on ones that we might not like as much. right. so in the past, people, if they didn't like a candidate or if they liked a candidate, but they like two candidates, they might have to choose which one to vote. they're going to have to choose which one to vote for. and they want to choose the one that may be more likely to win. this time, they can vote their sincere, policy based or ideological preferences. the problem is, though, is that with so many candidates, you know, we don't have a runoff process. and so i think the process is a little bit more complicated for most people. >> yeah, it is a little complicated. that's why i want to show people how it actually works. and i found this useful and kind of funny actually. little mock ballot in the san francisco voter guide. i think it uses vegetables. you can see this right here. you only get five choices, right? i think on the actual ballot for mayor, you

have ten. but explain to me, okay, if i'm choosing, let's say peppers, my first choice. but pepper comes in last in the first round, you know, tell me what happens to my vote. >> right. so everybody ranks as many vegetables as they possibly can in order. even broccoli, i suppose. and what happens is they tally up the first choice votes and the lowest ranked, you know, vegetable gets eliminated from the tally. and then all those people who. so let's say that, well, you know, maybe. okay, so if you have broccoli first and broccoli is eliminated right. then your second, you know, your vote goes to your second choice vote vegetable. so for instance, if it's carrot right then your vote goes to carrot. and then we tally the support. then again the last place candidate is eliminated you know. so perhaps onion is gone at that point. or spinach. and then your vote then would go to would remain with carrot until there's a, there's a vegetable that has a majority of

the remaining ballots. right. so as long as carrot finishes in the top two or top three, as long as carrots there when there's a majority achieved, then your ballot is counted. if it's not, though, let's say that you don't rank anything other than broccoli on your ballot. or maybe you. you rank broccoli and onion and carrot, but the last two are pepper and spinach. well then your vote actually doesn't count as a part of the continuing ballots to get a majority because you didn't include one of the final two candidates or final candidates on there, right? so that's a major issue with ranked choice voting. this problem of exhausted ballots. and what we find is that the winner of the race usually gets about 45% of all ballots that were cast in that election, rather than a full majority. >> okay. so for voter, would you suggest then putting down every choice that you're allowed to choose, like don't leave any choices blank, like fill out the top five or if it's the real ballot, fill out the ten. all ten of your choices. absolutely. >> okay. san francisco voters are going to have ten choices. i think it's very difficult to

rank ten choices, but use as many as you have available to rank. then your vote will be guaranteed to be a part of that final tally, and especially those top five candidates. i would say you need to rank thos. there's been a lot of the candidates themselves who are saying vote only for me. leave the others off the ballot for strategic reasons. and i actually think that's doing voters a disservice. voters themselves should rank as many candidates as they possibly can and, you know, use those use those ballot rankings. we only used to have three in san francisco. now we have ten. use as many as you can. >> okay. now, theoretically, from what you said, it sounds like this system could actually be more reflective of everyone's true will, including how much or how much they like or dislike each candidate. but i want to point out an example, because it's often cited in the ranked choice conversation. in oakland, for example, oakland mayor chantelle, currently facing a recall and an unpopular former mayor, jean quan, nearly faced a recall, both one under ranked choice after multiple rounds when they didn't lead in the first round. now, because of

that, some local voters see ranked choice as a way for a candidate who otherwise wouldn't have won to win. and by extension, maybe the system doesn't reflect popular will. how should we look at this? and as we talk about this, as you explain, i want to put up, you know, a screen that shows i think, the first round, eighth round and ninth round from that election in 2018, when chantelle won. >> right. i think it depends on how we define popular will. right. so in theory, ranked choice voting, you know, if you fully rank your preferences, then the person who wins is going to have a majority of support. after we consider all of those rankings and other candidates are eliminated. so it's one way to form a majority. and the popular will given again the exhausted ballots and continuing ballots. myself, i actually think that the previous system that we had in san francisco and in oakland beforehand, where the top two candidates, if no one gets a majority, they proceed to a runoff election, usually about a month later. and then i think, you know, the voters have a sense of, okay, there's two candidates. and choosing between them. that's also then a

majority guarantees a majority, right? so i think it depends on how we how we define the majority. i certainly don't think ranked choice voting produces illegitimate winners, but i do think it psents a potential problem for candidates like you. like like shantel in oakland and jean quan before her that if they win with, you know, a strong sort of first choice support from their base of support, but very less support. you know, or weaker support from others in the city that if they get in trouble, then they have less of a base of support to, to, to sort of rally from. and we saw this with chesa boudin recall in san francisco as well. he got about 36% of the vote on first choice votes. did that contribute to the recall? perhaps? >> i see, although in this set of graphics, you can tell that tao and taylor were very close from beginning to the very end. so who knows if there was a runoff, what would have happened? right? instead of just more of ignacio de la fuentes third place votes, ending up with more to tell, obviously. but okay, so obviously, you know, do you think this is going

to gain in popularity, right. or do you think we're going to lose faith in this particular system? what is the momentum and the trend saying, well, well, nationally ranked choice voting has become more popular. >> people used to not have any idea what it was and what i studied, and now they they're likely to have heard it. there's a lot of sort of reformer support behind it. some states are adopting various versions of it, including alaska and some others. so i think it's growing in popularity nationwide, although there's a partizan gap, republicans have turned against it for various reasons, especially locally, though i think we've been a little lucky, especially in san francisco, that we haven't had someone win the mayor's race without finishing in first place. i think there's some. there were some possibility that people, if that happens, this time around, we might see some movement to get rid of it. but mostly i will say this. the people who use ranked choice voting in san francisco and other cities, when we surveyed them, they report satisfaction with it. so, so far

people are satisfied with this. i think that it might change depending upon who wins. >> professor jason mcdaniel thank you so much for

co-founder of january i. >> i'm actually in the process. i just downloaded your app. can you tell us more about january i and how it works? >> absolutely. january i is a generative ai that predicts your next glucose level. and we've done years of research, seven years of research with continuous glucose monitors and smartwatches and user reported data like food logs. and we're able now to be able to give people an idea of how their food and activity might affect their blood sugar. and the way it works is a multimodal. you can

take a picture of your food for example, and it will give you your constituent ingredients. it will give you the macros and it will give you a predictive curve for it. it will tell you it might work. you know, you might spike to this food this way. and it does more than that. it helps you then edit that food. you can check it on, check essentially ingredients to see what their impact would be. you can also change their quantity. you're looking at alternatives right now. you can look at food alternatives like what might be healthier to eat. and also jan, the ai coach can also suggest things like how to add fiber to your food or how to swap out certain ingredients or meal plans or activity plans, etc. this is so neat because there's been so many times where i, you know, i've been trying to plan out meals for the week and i want to make some healthy choices, but you don't necessarily know how that's

going to impact. so to be able to have that planning feature is great. so there's a food scanner you mentioned and a nutrition tracker. how does this help make people change what they eat >> well, basically we try to understand some basic information about you, like basic demographic information like height, weight, gender, age and a number of other things like that. and from that we're able to understand, for example, how many calories a day you could you could manage without adding weight. we could we then translate that into macro targets for the person. and they can, by the way, update those macro targets if they want to. and then we try to keep them accountable to those things. and that's where ai coach is really helpful to be able to essentially see if you're sort of, you know, if you're having a big lunch, then to try to help you to have a very, you know,

much smaller dinner or you're not sleeping enough, which, you know, it really increases insulin resistance to try to guide you towards more sleep. so

tonight, breaking news, donald trump at a campaign event, imagining guns shooting at liz cheney. tonight kamala harris says this violent rhetoric makes trump unqualified to be president. just four days to go, and the tiny
