the presidency and they deserve to be investigated. what the republicans are doing now is they're trying to drag that out. to focus as much attention as possible on it. itself. >> congressman smith, that's our last word tonight. thanks for joining us. chris hayes is up next. tonight on "all in" -- >> we have to finally once and for all fix our fix our immigration system. >> hillary clinton dropped a policy bomb on the campaign trail, as another republican announces his candidacy by possibly breaking finance law. >> if you want to give a million dollars, please do it. >> then separating facts from propaganda as isis claims kred it for the texas attack. and joy reid reports on the two baltimores.

the inner harbor versus the inner city. >> somebody somewhere saw something they should have been paying for. >> how tess la's announcement could change the world. i'm chris hayes. something happened just a few hours ago that could prove to be one of the most significant developments of the entire cycle. and we have another entry into the race on what was a big day for the state of arkansas, as two politicians with deep ties to the state made major news. first, former governor mike huckabee declaring his second run for the white house and a former arkansas first lady hillary clinton making a major policy announcement on a potentially decisive 2016 issue. we begin in hope arkansas where huckabee made his announcement which also happens

to be the birthplace of bill clinton. huckabee is hoping for the choice of social conservatives. though unlike in his 2008 presidential run when he won the iowa caucuses huckabee faces stiffer competition for social conservative votes. ted cruz rick santorum and others. >> witness the slaughter of over 55 million babies in the name of choice, and we're now threatening the foundation of religious liberty by criminalizing christianity and demanding that we abandon biblical principles of marriage. >> here's how the event kicked off. ♪ it's been three long years, do you remember ♪ ♪ >> yes, tony orlando was in the house. although huckabee's rollout was

not quite as smooth. huckabee told his audience his campaign would be funded by small donors not billionaires, before adding this. >> now, rest assured, if you want to give a million dollars, please do it. but i know most of you can't. >> the supreme court has knocked down most of the limits on campaign financing particularly through super pacs and her agency is largely unable to enforce the laws that do exist, it is still, just for the record, to just hand the candidate a million dollars and for a candidate to solicit that much money, which means as "the washington post" pointed out, huckabee kicked off his campaign with a possible violation of campaign finance law. more on that in a bit. but first, we take you to roncho high school in las vegas where hillary clinton joined a student round table this afternoon and made a very important declaration, staking out a clear position for a path to

citizenship for undocumented immigrants. clinton's announcement made it a high school where 70% of students are hispanic puts her in line with most hispanic voters on an issue that continues to cause major headaches for republicans. even jeb bush prefers to talk mostly about legal status for undocumented immigrants and has only offered tentative support conditional of a pathway to citizenship. >> make no mistakes. today, not a single republican candidate announced is clearly and consistently supporting a path to citizenship, not one. when they talk about legal status, that is code for second class status. >> i was at that high school in

2008 at a caucus which descended into a chaotic debacle back in the early days of that campaign. but two things there. hillary clinton won a huge share of the hispanic voters in that democratic caucus but she was rhetorically taking a tough line. remember that license moment where she said she wouldn't favor it. she talked about deporting anyone who committed a crime no matter how minor. how big a step was this for her in this campaign? >> well i think it was shocking chris. you laid it out, her campaign signaled this morning to the media that she would be going for a path to citizenship. that was obvious. she had to stake out that territory. but she sprinted way past that evolution today, chris, as you laid out. she didn't just support president obama's executive orders, she said she'll put out her own executive orders anything within the law necessary. she supported family

reunification. she talked about the tension. she said essentially everything that the prototypical dreamer or hispanic voter would want to hear. we always complain about politicians not taking any positions, dancing around the issues. there was none of that today. i think she was baiting the republican candidates to come after her, call it amnesty, say it's lawlessness, say whatever you want she's going after that demographic. >> john makes a great point that this wasn't wishy washy. she has now enunciated a bunch of positions she now has to defend or essentially flip from. they're on the record. i remember when mitch mcconnell referred to the president's executive actions as waving a red cape in front of the republican caucus. it seemed like that is what was

happening here today at least politically. >> i think there's going to be a huge contrast between the parties because her position is so clear and they're divided. they either want to build the wall as high as they can and electrify it or whatever disturbing imagery they're using to describe immigration from mexico these days. or they're in the rubio-jeb bush camp where they're caught in the democratic light position. just take the position and hillary has just taken the position today. i think we're going to see them run into trouble all throughout this race because they're not willing to go that far. and the ones who have staked out a clear position is a completely untenable, really upsetting one for most americans. most americans understand that the country is built on immigration, and we don't feel fear about immigration. it's not building a wall. that's just not going to work for most people. >> john this also to me

symbolizes to what jess was saying where the center of the democratic party is. this was i think, a surprising announcement in that it went out past what this president has done. but this didn't come about -- i mean, this is the work of ten years of organizing by the folks you were mentioning to really push the democratic party on this issue. >> it's very true and it's emblematic of what's happened in nevada when harry reid several cycles ago, realized the changing demographics the burgeoning hispanic population. maybe 20% of the electorate in nevada in november 2016. i don't want to look at hillary clinton's heart whether she really believes this or whether this was political pandering. the republicans can say that all they want and it may be true but all that cohort of democratic voters cares about is where she is now. think about how few swing states

there are, and the ones that have hispanic populations that could be pivotal, such as nevada, colorado, florida. so whether or not she really believes this or has come to read polls better it doesn't matter. this is a very significant move and she can't come off of that later on because she was very firm in what she said. >> she also did a really smart thing by couching immigration policy and her agenda for immigration in a family issue. 75% of the immigrants in america are women and children. when i say mexican immigrants to you, the first thing you think of is probably a guy. you're probably thinking of somebody who is going to come in and work a job and take care of a family and maybe bring people over. 75% are women and children. when she talks about this issue as a women and families issue, she's relating directly to the people who are living that experience. that's why it's so smart and why

it's going to resonate for a really long time. >> john jeb bush, who is sort of widely seen as the sort of quote unquote most moderate on immigration, although that term can be very hard to pin down. he put on a cinco de mayo announcement today in his pretty good spanish. jeb bush is caught between understanding what the general electorate wants, what the primary electorate wants and it seems to me he's going to try to get over with some ambiguity and his personal story of being married to a mexican immigrant. >> it's very interesting, chris, one week from tomorrow jeb bush will be in nevada. why will he be there? he's giving a speech to the clark county republican dinner. that is dominated by the people who called for reince priebus'

resignation, a lot of tea party types. it's going to be fascinating to see what jeb bush says to that group of people. this is a very difficult needle to thread to talk to that republican primary electorate and preserve his viability in the general election. i think that speech is going to be very emblematic of what he has to do. >> great point. thank you both. at his presidential announcement today in arkansas mike huckabee said something you don't hear from a lot of republicans. >> if congress wants to take away someone's retirement let them end their own congressional pensions, not your social security! >> huckabee's economic populism at least on benefits for the elderly, flies in the face of the gop donor class orthodoxy. the club for growth today unveiled an ad attacking huckabee's record on taxes and

spending as arkansas governor. club for growth says it will spend $100,000 to air the spot in iowa and south carolina. joining me now is rick wilson. rick, it's great to have you on. this issue is fascinating to me. i have a theory about the republicans and social security, medicare. back in that budget fight in 2011, when the president was seeking a grand bargain, my theory is that john boehner knew full well that the republican party didn't want to see cuts to social security or medicare because the republican base doesn't want that. they're disproportionately elderly, and i feel like that's what mike huckabee is tapping into here. am i getting that wrong? >> look even the republican base voters -- where social security and medicare are elements in their lives, recognize the system is largely

unsustainable. but what huckabee is doing is what he always does. he finds a cheap brown trout into the populist pool and he's always going for that kind of thing to find this mythical niche in the republican party where this arkansas style descended from the great stump screamer politicians is going to work on a national stage. most of the republican voters realize that he's not a limited government conservative and those are fundamental in republican politics. >> there's this quadrant -- >> where do you fall? >> that's right. so i was a leftist through and through, even at a young age. there's this quadrant that you

can argue is unrepresented in american politics essentially people that are socially conservative opposed to gay marriage opposed to abortion want sort of -- are fine with the state regulating personal behavior but are economicicly populist. it remains to be seen whether there are vote there is or whether there are vote there is but the donor class is so a anathema they won't let them get the votes. >> he is not a limited government conservative. that is the main stream of the republican party. they are the rising faction of the party right now. we've seen some decline of the foreign policy hawks over the last few years. they've started to come back a little bit. but that era or that area of

evangelical populism that huckabee would try to occupy is narrower than in the past. and huckabee is a guy, they look back at the record he raised taxes consistently. he talks about cutting taxes, but the net number was over $500 million, which in arkansas was real money back then. this is a guy who doesn't have a fundamental foundation in the thing that most republican voters care most about, which is fiscal restraint and limited government. >> it's interesting, his record in arkansas is fascinating on that score. >> it is. it's historically interesting. >> it is. and he did a lot of things that liberals hated, he did a lot of things that liberals liked. he increased spending in certain areas that folks did not anticipate. it's always striking to me how much constituency there is for that kind of thing. you're saying there's not much right now and we'll see how this plays out. rick, great pleasure to have you

the islamic state or isis has claimed credit for the texas attack that resulted in the two attackers being shot dead. on its radio station isis said the two men were soldiers of the caliphate and added, we tell america that what is coming will be even bigger and morabilitier and you'll see the soldiers of the islamic state do terrible things. the two men opened fire with

assault rifles in texas sunday where people were invited to display caricatures of the prophet muhammad. a school district security officer was shot in the ankle, but a police officer returned fire, killing both suspects. it is unclear whether the two attackers were in fact connected to isis in any substantive way. what's more telling perhaps is how determined isis seems to be to claim credit for an attack which the suspects were so quickly taken down. joining me now with the latest is amman. what do we know about the degree to which there's an actual operational link of any kind between these two men and isis? >> reporter: well, at this point, we certainly don't know a lot to be honest with you, chris. the information does not seem to indicate a operational link between the organization and these two suspects. according to the maternal grandmother of nadir soofi, she said it's unlikely of her son

carrying out this attack without being under the influence of someone else. elton simpson was on a terror watch list and convicted of lying to authorities about his intent to join a terrorist organization overseas. ultimately, the judge said that the prosecution did not have enough evidence back in 2011 to substantiate the claim that he did, in fact want to join a terrorist organization so he was released on probation. right now, the investigation is going to focus on all kinds of evidence including whether or not there was any kind of operational link with the group, including training perhaps associates or affiliates within the united states that may have facilitated any of this attack. we understand from our own reporting that the guns used in this attack were purchased legally. again, we don't know the linkage between these two individuals and isis if there is one. chris? >> this gets so someone we discussed before. the degree to which isis has two sides to it.

there's the actual army that is fighting soldholding ground losing ground in iraq and syria. then there's isis as this global brand that various jihadis want to associate with around the world, whether or not they're in communication with them. >> reporter: yeah there's no doubt isis has tremendous command and control over the territory it controls inside syria and iraq. sit a major force on the ground in a lot of that territory. when it comes to operational cells that have been operating in the west, to this date there's not strong evidence to suggest that isis as an organization was behind any of these attacks, which means those that carried out those attacks were provided weapons, trained,

or provided support. what seems to be the pattern is that they want to inspire people in the west to carry out attacks. that is a real threat and the major cause of concern for western officials. these lone wolf attacks, and reading and interacting and engaging with isis supporters anywhere in the world and feeling that they now want to be inspired by the organization and carry out those attacks. so there is this propaganda value of something like what we saw in garland that isis benefits from. it says to the recruiters we are bringing the fight to these western streets. we are capable of inspiring others and that is the real challenge for law enforcement officials to prevent those individuals from being inspired of carrying out attacks that could be deadly and just as terrorizing. >> at one level, plots like the one that happened in texas are are -- they're less logistically

sophisticated, so their scale and scope is reduced. but also, they're harder to sniff out, because presumably you have one or two people involved in them and it makes it more difficult for authorities to catch them. >> no doubt about it. that is -- when we speak to law enforcement officials, they tell you they're always concerned about that one individual or those individuals that operate in pairs, perhaps like the boston marathon bombing, who can become radicalized and create or carry out attacks in contained environments that have a much larger impact in terms of the casualties and fear factor. that is a major challenge for law enforcement officials. they have been successful in preventing dozens of people from leaving the united states going to isis controlled territory, acquiring battlefield skill sets. but the challenge for law enforcement is terrorists have to be successful only one time and not successful all of the

times. that's what we're seeing with these lone wolf attacks. their impact sometimes is psychologically much greater than what they're capable of carrying out. but just as disastrous. >> thank you very much. still ahead, two very different views of baltimore. >> if you're trying to build, build from everywhere. don't just build suburban areas or the inner harbor or the counties. build the inner city where the urban people are at. >> that's ahead.

i thought it was important that i come here also to hear from people who are on the ground, people who are in the city, and frankly, people who love the city. as we all know baltimore has come to symbolize a lot of the issues involving police and community mistrust that plague so many of our cities. >> one week into her new role as attorney general loretta lynch traveled to baltimore today where she met with city officials, community groups and police officers. she also sat down with the family of freddie gray the man whose death triggered unrest throughout the city. last month the justice department launched a civil rights investigation into the 25-year-old's death in police custody and the national

spotlight on baltimore has only highlighted what residents have known for decades, it's a city struggling with racial inequalities. >> reporter: the story of baltimore is a tale of two stark economic realities. since the 1980s the inner harbor area has benefited from massive public investment creating a magnet for tourists and residents alike. but there's another baltimore. the baltimore where freddie gray lived and died. that baltimore sees the investments in the inner harbor and asks how can a city that can afford that let this go on? on the streets and barber shots of west baltimore, residents know this neighborhood was in decline long before freddie gray died. >> we been have these abandoned buildings. these places have been boarded up. >> reporter: add to that the sentiment that the investments in the inner harbor take away from the investments in the urban center where is 1/3 of the

residential buildings are abandoned and you have an anxiety that runs deep. >> if you're trying to build, build from everywhere. don't just build the inner harbor or the suburban areas, build the inner cities. >> what we saw, when we look at the police brutality, it's symptoms of a deeper problem of investment that goes downtown but not uptown. >> reporter: but some activists understand the economic importance of the inner harbor and are working toward a day when the two baltimores became one. >> we need all the neighborhoods up here and we all work together as one ecosystem as a city. the more we can get neighborhoods like this to feel like the entire metropolitan region is theirs it will stop being a tale of two cities. >> that was joy reid reporting. she joins me now live from baltimore. joy, this is something that

when i was there last week it was amazing to me how often people wanted to talk about the investments in the inner harbor, about the rejuvenation in certain areas and not others. who do folks sape about ss saying a it? >> reporter: people essentially are looking at the inner harbor and say that's where all the treasure goes it it goes to the county downtown, the harbor. but one of the challenges she talked about the difficult issue of even trying to rebuild a place like west baltimore. first, you would have to figure out who the owners of the buildings are, finding a chain of custody of that property would be the first step in even attempting to rebuild that area. the inner harbor is owned by the city or the county. you then have this issue of who would invest. how do you do it in a way that doesn't gentry fie the

neighborhood and price out the people there. then you have the issue that the west and east baltimore sectors are residential. with some retail so you have to figure out a different kind of development. so it's kind of apples and oranges, but people look at that harbor and all those glittering stores and say, what about us? >> here are just a few maps. this is children living below the poverty line from 2009 to 2013. you can see how those dark purple precincts are high levels of poverty. and joy, this is -- the neighborhoods -- that neighborhood where freddie gray was, that's as poor as a neighborhood in america gets basically. >> absolutely. you have situation where is you have over 4 in 10 people taking more than 30 minutes to get to work every day. think about that. i'm not talking about in a car.

people are cut off from the lifelines of the city so even if they could get a job interview, how would they get there? we were there one day when people said they had been waiting over an hour for a bus to take them east to west to get them downtown. people are standing on the corner waiting for a bus. you have a train stop there at the west baltimore area that doesn't go all over the city. it will only take you so far. so you have fundamental issues of just being able to move people to where the jobs are. you have a high percentage of people in that community who are coming back from incarceration, so they can't even get an interview, let alone a job. >> and let's also say this. this is not limited to baltimore. i mean the model that baltimore has pursued of urban development has been the model a lot of places have pursued.

there are restaurants and services and start-ups that they create, but it's unclear that that model has done much for very poor neighborhoods, whether the bronx where i grew up, or west baltimore. >> reporter: absolutely. detroit, all of these communities have one thing in common. you have a cache of poor people often times african-american, which live downtown which used to be the undesirable part of town. now that's the most desirable area. what do you do with the people who are already there and how do you redevelop an area where there's no obvious economic benefit for the investors. so when you don't have an obvious return on investment it's just difficult to figure it out. again, you go into the areas where you see rows of boarded up houses. that was already like that.

you can't even figure out who owns it. a lot of them are land lords long gone. so the city would have to seize it. >> jobs if you don't have jobs for people you're going to have a lot of poor folks. joy reid, thank you. still ahead, a look at the technology that allowed thousands of people to watch the highly anticipated and expensive pacquiao-mayweather fight for free. when it comes to good nutrition...i'm no expert. that would be my daughter -- hi dad. she's a dietitian. and

we have -- we have this handy fusion reactor in the sky called the sun, okay? you don't have to do anything. it just works. it shows up every day and produces ridiculous amounts of power. >> tesla's ceo elon musk might be the most ambitious businessman of our age. i think he certainly is. he pioneered a zero emissions car and now he's tackling solar power taking on the biggest obstacle of taking on solar power in this country. when it's nighttime or cloudy out, the panels aren't collecting energy. but musk has a solution, the tesla powerball, a unit that saves up the energy and saysist for a rainy day. it can only save 10 kilowatt hours. according to tesla, your refrigerator alone eats about that much per day, but appears to be something towards making solar an alternative.

it's set to ship this summer and the 10 kilowatt model goes for the relatively affordable price of $3,500 plus the cost open installation. he revealed a commercial selection of the battery called the power pack which is designed to be infinitely available. >> you can transition the united states with 900 million, you can transition the world. you can basically make all electricity generation in the world renewable. and primarily solar. >> joining me now, david roberts and tech consultant adviser shelly palmer. david, let me start with you. you just wrote this piece about solar being essentially inevitable. how big was -- how big a problem is the battery problem? how far did musk get with this announcement?

>> well, i think mostly what he did with the announcement is open people's minds to the possibility. i mean, currently, batteries are still too big and bulky and hold too little power to make solar dominant, more than sort of an add-on to other forms of power. but, you know, technology continues to develop, solar cells are going to get smaller and more efficient and batteries, also, and other forms of energy storage are going to get smaller and smaller. eventually, it won't be some big thing stuck on your wall. it will be integrated into your home and the solar cells, too, will be integrated into your home. the home themselves, the buildings themselves will become harvesters and energizers of storer unobtrusively and energy. >> the problem is sort of a consumer option, right? what we've seen right now is solar is going through this tremendous revolution because the price has just dropped in this way that we -- totally unprecedented, right?

but there's this viral effect. there's studies out that say people that see, have neighbors with solar panels are more likely to get solar panels. >> i think this is about a mission and a vision, right? if you are part of this idea that you want to live a sustainable life, but tesla car is a lifestyle and the power wall is a lifestyle choice. it is too expensive, but you know what's interesting? it's right on the cusp of being financially sensible. it's not there, it's right on the cusp. but today, as i love to say, is the slowest rate of technological change you will ever experience for the rest of your life. so it's going to get there. but right this minute, truly, there's this whole total continuous output where you literally can't get enough electricity out of this thing to run your house. forget about that. you will be able to do it. and you're right, it is slightly viral, but it's a lifestyle choice. >> david, here is the argument you made in the piece. hammer home why solar is so distinct from everything else. why it's not like any other kind of power. >> sure.

every other form of commercial electricity generation works basically the same way. it translates mechanical force into electrical current by spinning a turbine. so everything else, coal, natural gas, nuclear, wind, hydro, they all are about spinning turbines. solar pv is the only commercial form of electricity that creates electricity directly from sunlight. that means without moving parts, which reduces the upkeep and operational costs, and it's the only form of power that can eventually be scaled down to virtually any size. i mean, musk emphasized that it can be scaled up, but it can be scaled down theoretically to a square inch. so you can imagine solar becoming ubiquitous in a way. >> what's really important here is not can you power an american household or use this in lieu of a backup generator, if you think about this in nations where

there are no power grids, this takes on a new sort of possible -- set of possibilities where you've got -- look, there are cheap batteries and there are cheaper batteries. this is the cheapest battery that does what it does that we've seen in a while. my suspicious is once the giga factory is put up, this is going to become affordable to the point where it makes sense. >> and the giga factor which is set to become to nevada, they're going to make these things to make batteries. david, i had someone tell me that they actually thought tesla was really tesla really is a battery factories. the thick that they understood people are going to need in the future is batteries. they had to fix the engineering the battery problem to make their car, but the car in some ways is ancillary. it's actually the battery that is the business. >> that's right. the best way to look at electric cars, in some sense, is as portable forms of electricity storage. you can imagine a future where

all these electric carries are hooked up to the grid, so grid operators, when they need extra power can draw power from all these distributing cars. when they don't need power can return power to those batteries. so it becomes a distributed form of storage. >> yeah. and you wonder, also, how much -- how much the sort of effect of someone setting targets the way musk has impacts competitors, right? >> it's going to be really important because you've got a battery industry. look, we have a very fast technological advancement curve. the two slowest things, literally, have been battery technology. look at your cell phones, look at your power ever where. >> the biggest fight. >> you want to run an airport, charge, charge, charge, everybody is trying to charge their phone. and, of course, solar cells, because if you had 100% absorbed material, it would be invisible and the greatest solar cell ever. we're not there yet. you have to come along, i love the fact that elon musk is the tony stark of our age.

>> that presenting. >> thank you both. >> that is all in for this evening. the rachel maddow show start now. >> nerdly uncomfortable wasn't a segue to me, was it? >> no. nerdly self-assured and deeply comfortable. >> obviously. >> that's what i'm talking about. >> thanks, man. appreciate it. thank you for joining us this hour. the first time a presidential debate was televised was 1960. that 1960 debate is probably still the most famous american presidential debate of all times. right? thanks mostly to the fact that richard nixon was famously -- in that debate and, therefore, a little shifty looking and john f. kennedy looked cool, calm and collected under a layer of powder foundation. that first debate was filmed in the chicago studios of cbs, but it was a join production and it was jointly br
