>> this is aljazeera america live from new york city, i'm stephanie sy. this morning, hillary clinton and donald trump are setting their sights on november, and each other after big super tuesday wins. trump won seven states but lost the biggest prize, texas to ted cruz. cruz also won oklahoma and alaska. senator marco rubio got his first win with a victory in the minnesota caucuses. on the democratic side, hillary clinton also won seven states holding off a challenge from bernie sanders in massachusetts. the vermont senator had victories in four states. randall pinkston is tracking the republicans from west palm beach florida, but first, david shuster has a look at how last night turned out. >> this has been an amazing

evening. >> what a super tuesday! >> hillary clinton and donald trump are now barreling ahead on the path to nomination. the two emerged as the front runners after super tuesday, solidifying huge leads. >> it's clear tonight that the stakes in this election have never been higher. the rhetoric we're hearing on the other side has never been lower. trying to divide america between us and them is wrong and we're not going to let it work. >> clinton swept the south in the democratic primaries, minority voters broke for her 4-1, fueling her southern domination. for bernie sanders, the delegate map is becoming more difficult, but sanders is not giving up. he won four more states on tuesday.

>> we have come a very long way in 10 months. [ cheers and applause ] >> at the end of tonight, 15 states will have voted, 35 states remain. let me assure you that we are going to take our fight for economic justice, for social justice, for environmental sanity, for a world of peace to every one of those states. >> super tuesday was also a wake-up call for the republican establishment. donald trump widened his margins across nearly every demographic and captured six states. >> we've done something that almost nobody thought could be done, and i'm very proud of it. i just want to leave you with this. i am a unifier. i would love to see the republican party and everybody get together and unify. >> texas senator ted cruz is campaigning as the only

republican that can beat trump if they are the final two. and oklahoma and is urging the oklahoma and is urging the other candidates to drop out. >> so long as the field remains divided, donald trump's path to the nomination remains more likely and that would be a disaster for republicans, for conservatives and for the nation. >> marco rubio is holding on. he won his first contest in oklahoma and now is focused on his home state of florida where the results will be winner take all. >> the pundits say we're underdogs, i'll accept that. we've all been underdogs. this is a community of underdogs. this is a state of underdogs. this is a country of underdogs, but we will win and when we do,

we will do what needs to be done. >> the presidential race is still far from over, but the math is pointing towards an unusual choice in the general election, a brash and unconventional businessman versus a controversial former first lady. david shuster, al jazeera. let's go to john terrett in vermont, bernie sanders hometown. sanders did manage to win four states, including his home state, but is far behind right now in the delegate count. what's his camp saying this morning? >> well, it's interesting you should say that because i'm standing on church street in burlington, vermont, which is now a pedestrian precinct, so you don't get vehicles up here. it was bernie sanders brain child. his campaign headquarters is over there. i'm looking at it right now. he's been here in this spat for years and they just had a briefing with journalists and

their plan is to go on. they have plenty of money in their swag bag and plans to go on. last night, when bernie sanders came here to what amounts to the state fairgrounds just outside burlington there were i thought a couple of subtle hint that things aren't going maybe the way they would like and maybe this is more about pushing the clinton campaign to the left and bringing things to the national agenda that bernie wants to be talked about. nonetheless, the message overall last night was that the revolution as the candidate calls it, goes on. take a listen. >> wall street may be against us and the super packs maybe against us, but you know why we are going to win? because our mental is resonating and the people when we stand together will be victorious.

>> as i said and as the campaign said, they are concentrating on the midwest, those states where bernie sanders feels naturally at home and he feels he can do well. we'll see how he gets on the next couple of weeks. one thing of note, they do have a lot of money in the bank, raised six or $7 million before the close of deadline on monday evening. they've now got $41.6 million in the bank just for february, so have plenty of money so they can go on being a thorn in the clinton campaign right down through the convention in july, which mrs. sanders said yesterday on the program is what she intends to do. >> hillary clinton hardly said anything about senator sanders in her victory speech. she seems to have her eye trained on trump now. >> yeah. i think that's the strategy and we noticed this last week. she barely mentioned him, really, at the weekend when she

won south carolina with such a lopsided victory. it was a huge victory for her there over sanders. sanders pretty much gave up in south carolina. she said when she took her acceptance speech in south carolina on saturday, she said tomorrow, meaning sunday then, this campaign goes national. i think that's been the tone of the clinton campaign ever since, barely mentions sanders, really talking about the republicans. there's a survey out in the last couple of days saying americans think it's going to be a clinton-trump election in november. she's in an awkward position. she knows she needs to bring the sanders voters along with her if she is to be the nominee and at the same time, she is also aware that she's probably doing reasonably well because of the rise of donald trump so keen to position hearses as the antithesis to him in every way. let's take a listen to her acceptance speech last night. take a listen.

>> instead of building walls, we're going to break down barriers and built ladders of opportunity. >> going forward, hillary is going to be in her home state of new york tonight and bernie sanders on his way to maine for the day and michigan this evening. >> john, thanks a lot. with the victories last night, donald trump has widened his delegate lead by a lot. trump has 10 primary and caucus victories, bringing his total delegate count to 285. he needs 952 more delegates to win the republican nomination. randall pinkston is live in west palm beach, florida where trump

addressed his supporters last night. in typical form, he took aim at his challenger and at the democratic front runner. >> yes, typical trump. trump's triumph is a headache for many of the republican party who consider themselves members of the establishment. one in particular, the former governor of new jersey, christie saying that if trump is her party's nominee, she will not vote for him. throughout this campaign, trump has insulted his opponents, even a former republican president, george w. bush, accusing him of not protecting america, but as trump has continued to gain support picking up more delegates, he is beginning to moderate his rhetoric, speaking here in west palm beach last night, trump says that he can unify the party. >> i'm a unifier. i know people are going to find that a little hard to believe, but i am a unifier.

once this is finished, i'm going to go after hillary clinton, assuming that shies going to be allowed to run, which is a big assumption. i don't know that she's going to be allowed to run. i beat hillary in many polls. i don't think marco's going to be able to beat her. in all fairness, i think ted's going to have a very hard time but ted has at least a shot, because at least he's won a little bit. >> of course donald did have some more strident things to say about marco rubio but he was mostly kind to ted cruz who remained in this race, still insisting that they have an opportunity to win the nomination when death toe cleveland. trump heads next to michigan for the debate tomorrow night. stephanie. >> ted cruz was able to hold on. he won three states last night. marco rubio won his first contest. what does it mean for these two

candidates moving forward and looking ahead to march 15? >> obviously for ted cruz, winning texas is several. that is his home base and he proofs he has substantial support there, delegate rich texas. here in florida, it remains to be seen whether marco rubio can do the same. he needs to win his home state here in florida. he only has one victory, marco rubio does and if he can't win florida, it's hard to see any path that gets him to a plausible nomination in cleveland. as long as the contest remains divided among three, four, five candidates, we still have dr. ben carson, john kasich in it, it's a path to victory for donald trump. >> randall, envoy the weather and thank you. >> an attempt to keep it ted cruz off the ballot over his citizenship has been thrown out.

the suit filed by a chicago attorney argued cruz is in eligible to run for president because he was born in canada. a judge threw it out on a technicality. his mother was a u.s. citizen when he was born in calgary. >> a lawsuit against donald trump over his trump university is moving forward. an appellate court rejected trumps request to throw it out. it charged the school used bait and switch tactics, encouraging students to enroll in increasingly expensive classes. the school shut down in 2010. six new jersey newspapers have apparently had enough of governor chris christie. they are calling on him to resign. the papers put out a joint editorial calling him an embarrassment and disgrace, pointing to his endorsement of donald trump and his absence from the state as he ran for president. up next, the supreme court hears a landmark abortion rights case. the texas law that could affect

clinics nationwide. apple takes new steps to fight the f.b.i. request to unlock an iphone.

now that super tuesday is over, one of the next major prizes is ohio. it has a history of picking the winner in november. we explain what the candidates have to do to win there.

>> mr. donald j. trump! >> every serious candidate has always been here and will come again and again. >> i love ohio. >> ohio is a microcosm of the country. you have every single part of the country represented right here in ohio. >> the state mix of urban and rural, wealthy and poor, black and white makes it known for picking presidents more than any other. >> now is probably one of a dozen of battleground states for the presidency. >> only a dozen. >> out of 50 states, there are only 12 where there is a real contest, that's been ohio for years and years and years. demographically, it mirrors the country. >> in the general election, that mirror has long cast a strikingly accurate reflection of what happens in the nation when all the votes are cast. >> ohio has become the gateway to the white house. every single president since

1964, johnson, nixon, carter, the elder bush, the younger bush and obama all had to win here first. the state votes within 1.3 percentage points of the national vote tally in the presidency. >> this year marks a turning point in ohio and the nation. for the first time, millennials, those born after 1980, will match baby boomers as a share of the electorate. >> we've grown up in a time where there's been a lot of economic hardship. >> that goes for young democrats. >> i can afford a republican president to be in office, i am white, male, straight and middle class, but for a lot of people that are in marginalized communities, they cannot afford republican. >> the rather than i think it should be bernie sanders is because of the consistent 40 years of consistent progressive policies. >> millennials like me are very invested in protecting gay rights, protecting the ability to marry the one you love.

>> i'm for donald trump, because i want to make america great again, you know that, and build the wall, build that wall, donald. >> because of how it is. >> thank you. >> all of the candidates will campaign here aggressively. they know if their dream of the white house is to become a reality, they must win here. al jazeera, columbus, ohio. in 30-mile an hours, the supreme court will hear its first abortion case in almost a decade. it is looking at whether a texas law with strict new rules for clinics puts an undue burden on women. >> demonstrators have gathered here to make their voices heard in what's been called the most significant abortion case in nearly a quarter century. this case revolves around a 2013 texas law that put in place restrictions on abortion providers in that state. at issue today are two restrictions specifically, one

requires abortion doctors to have an official affiliation with nearby hospitals. the second requires abortion providers to meet a series of elaborate hospital grade standards. now that first restriction is in now that first restriction is in place already, in texas, the second is not. already, pro abortion rights activists say it has had a devastating effect on abortion providers in that state. we spoke to one activist early this morning. this is what she had to say. >> what it's really doing is just forcing providers to close their doors, and no longer provide services to women who need them. this isn't about increasing women's health and safety. it's about putting them in a precarious situation where they don't have access to care. june the court is down to eight justice, all eyes are on anthony kennedy to see how he will vote in this case. >> al jazeera with an update at the supreme court. jesse hill is a law professor at case western reserve university

and she filed an amicus brief in this case. earlier i asked her which way she thinks justice kennedy will vote. >> that is a big question mark in this case. justice kennedy famously joined the other justice to kind of uphold and save the heart of row v. wade in the 1992 case, planned parenthood v casey. since that time, he's been very hard to read on this issue. in 2007, he joined the conservative wing of the court in another abortion case in a really big loss for abortion rights supporters, and so it's really hard to read him right now. he's been very supportive recently of individual dignity and autonomy concerns in the same-sex marriage context and it's, you know, the plaintiffs, i think are really hoping and that's my amicus brief also talks about the idea that

dignity and autonomy are really important concepts here, too. if it were a 4-4 split, that means the lower court decision is confirmed by an equally divided vote, that means the law stays in lace and basically all but a handful of clinics in the accident would close. >> professor hill said whether the court considers scientific data and medical research on the relationship between women's health and access to abortion could affect the court's decision. she understands the appeals court that upheld the texas law did not do that. apple is raising the legal stakes in its battle with the f.b.i. the government admitted mistakes when it handled the san bernardino shooter's phone. >> apple has now filed a formal appeal of a judge's order that it help the f.b.i. unlock one of the san bernardino shooter's phones. al apple said it's out of an

abundance of caution. as a a judge reviews arguments in the case. the appeal came the same day both sides testified on capitol hill. f.b.i. director james comey refrained from painting apple as more concerned about profits than national security. >> the companies are not evil, the government is not evil, you have a whole lot of good people who see the world through difference lenses, all care about things. >> he admitted the f.b.i. and local officials made mistakes trying to get into the phone days after the shootings, putting through a password reset request that made it more difficult to get in. comey insisted the f.b.i. is not looking to get a back door into all iphones. >> there's already a door on that iphone. essentially we are asking apple take the vicious guard door away, let us try to pick the lock. >> the company lawyers said it cooperated with law enforcement on both criminal and terrorism cases. he said what the government is asking now would set a precedent that threatens millions of phone users. >> the f.b.i. has asked the court to order us to give them something that we don't have, to create an operating system that does not exist.

the reason it doesn't exist is because it would be too dangerous. >> members of congress from both parties say they understand why apple is resisting the order. some now call for a blue ribbon commission of experts to figure out a solution. the long term impact of an invisible gas leak, residents return to porter ranch, but some worry it's still not safe.

>> residents living near a now

capped natural gas well near los angeles are finally being allowed to go home. they were forced out as a leak spewed methane into the air. some fear it's still not safe to return. >> months after being forced away, joni spears has returned to organize what's left in her home. >> how do you explain this to your kids? >> they're going through a lot. they know that we have to make the right decisions for them and i think they've been preparing themselves to leave, but i think not knowing where we're going and what we're doing, it's frightening. >> spears is not convinced it's safe to live her anymore. the gas company has sealed the

well and residents started returning last week, but her health had improved while away and now she says she feels ill again. >> since i've come back the last several days in this past week, i've begun getting really sick again. >> other residents have reported health issues since returning to the porter ranch area and county officials say they'd actually like more time for additional air testing, including inside homes. >> what's the residual? what is left over in the air? what is left over in the atmosphere, in people's homes? what's been trapped in the sediment rock for almost four months? >> the most damaging natural gas leak took operation at one of the largest gas storage facilities in the country. most people had no idea there were 400 wells just over the hills from their homes. it sparked protest, a demand for accountability and lawsuits. >> you know, there are many lawsuits, i've heard up to 75. we've got our own lawsuit that we filed on behalf of the people

of the state of california working very closely with the city attorney's office. >> some residents will move past this and resume life in porter ranch, but spears plans to sell this house, despite her love for her neighborhood. >> i think it's probably in my opinion one of the most breathtaking places in l.a. county. where i saw this view when we were ready to purchase this house, i couldn't believe i was going to get to look at this every day. it makes me sad that this can happen in our country. >> the consolation for people who plan to move, housing prices appear to be holding steady. in fact, construction continues on million dollar homes right below the gas storage site, the disaster not a big factor apparently for some buyers, though others may think twice. melissa chan, al jazeera, porter ranch, california. that will do it for us. thanks for watching. i'm stephanie sy. the news continues next live from doha. have a great day.

hillary clinton and donald trump close in on one on one showdown, but other challengers say the race isn't over
