sanders doesn't have to start walk in few states he starts to start winning everywhere. and by large margins. that won't be easy because right now hillary clinton its leading in the polls in michigan, ohio, louisiana, and florida. four states that vote this month. scott, she is celebrating her big victory here in new york city tonight with a star-studded nd raiser featuring elton john d katy perry. nancy cordes, thank you. awe to make sense of this 'll turn to john dickerson, cbs news political director and anchor of "face the nation." john, a lot of talk among republicans of stopping trump. how practical is that? >> it is a long shot. there is definitely motivation. the anti-trump effort to rank the republican panic on scale of one to 10. he said 11. but harnessing that panic requires politicians and party regulars to organize themselves quickly. there is no leader of this effort. requires them to take a big risk. they don't like to be on the wrong side of public opinion. no guarantee. attacks from the establishment could make trump stronger. >> what is one of the most plausible approaches? >> i guess the shortest long shot would be to deny trump the delegates needed for the nomination. by launching a withering set of ads immediately in delegate rich states, ohio, florida, which volt on march 15th. the hope would be to tear trump down and give some other candidate a chance to win. then there would be no clear winner. and the delegates could be than trump in possibly more controlled environment of the convention. >> looking quickly at democrats. es sanders have a shot against llary clinton at this point? a very, very distant shot. is winning states. e is winning more than he is. e has a delegate lead. less something changes she is the way off to the mination. john dickerson. ank you. in houston, the police have released an incredible video today. it shows a team of thieves ransacking a gun store -- thieves ransacking a gun store. >> the burglary in the southwest houston gun shop was fast and furious. group of men pulled up to the front of the store, in a large pickup truck. smashed the windows. attached a chain to the doors and pulled them off the hinges. ten people rushed in and ran through the store, smashing grabbing handguns by the sackful. at this angle we see one man scoop up four rifles off the back rack. an early investigation shows the thieves got away with at least 50 weapons. scott, so far there have been no arrests. federal officials say, weapons stolen in this burglary will kely end up on the black rket and could be used in olent crimes. manuel, thank you. e "cbs overnight news" will be ght back. > well as donald trump was almost sixty million americans are affected by mental illness. together we can help them with three simple words. my name is chris noth and i will listen. from maine to maui, thousands of high school students across the country are getting in on the action by volunteering in their communities. chris young: action teams of high school students are joining volunteers of america and major league baseball players to help train and inspire the next generation of volunteers. carlos pea: it's easy to

preventable. all: osteo's preventable? right on! if you dig your bones, protect them. all: cbs cares! well as donald trump was pronouncing himself the winner, mark phillips tells us europeans were having trouble pronouncing him at all. >> reporter: they're trying to figure out the name. and they're trying to figure out the man. donald trump was once seen as a peculiar aberration of american politics. even as vaguely amusing. but nobody is laughing now. instead they're scrambling to taking trump lessons from those who know. >> on the phone his behavior was extraordinary, childish. >> head of the scottish government when trump was promising to build a glittering new golf resort there. a promise he never kept. >> then things soured very, very quickly. >> reporter: the european press has been full of apocalyptic foreboding, madness screamed the cover of der spiegel. really? asked the economist. ann mcillvoy, really what is spooking people. that is what he is running on. being changeable. pulling the rug out. being an event. >> reporter: if you want to know what people really think of donald trump, try the bookies where trump's odds are dramatically improving. >> the trump odds shortened up. he was 3:1. now 2:1. >> more likely. >> much more likely. >> 2:1, scott is a good bet. clinton's odds are even better. here is a sobering thought. in recent elections here and in the u.s., the book makers have been belter predictors of the result than the political pollsters. >> mark films reporting to night from london newsroom. mark, thank you. in an important story, the biggest abortion case in a decade was argued before the eight justices of the supreme court. this one is a challenge to a texas law that imposes tough standards on abortion clinics. supporters say the law protects patients. jan crawford is following this. it is the court's first controversial case since the death of justice antonin scalia. but the questions from the justices were no less intense. and reflected deep divisions. regulations raising standards for abortion clinics would force many to close. ultimately obstructing a woman's right to abortion for no good reason. justice ruth bader ginsburg, what it is about is that a woman has a fundamental right to make this choice for herself. the conservatives ask where is the evidence, the law would in fact shut down many clinics. justice sam alito, there is information that they closed for reasons that had nothing to do with this law. texas passioned the law in 2013, amid national outcry over a pennsylvania clinic where a doctor was convicted of killing a patient and three infants in botched late term abortions. the law requires clinics to operate more like surgery centerers and have doctors with admitting privileges at nearby hospitals. texas representative jody laudenberg sponsored the bill. that its what this is all about. women's health. and quality of care. >> reporter: amy hegtrom miller, ceo of the abortion clinic challenging the law said it was a smokescreen. >> this law is cruel. harsh and does nothing to advance medical health for women. >> reporter: the key vote here as in all abortion cases is the moderate conservative anthony kennedy. today he did not tip his hand. he did ask whether the court should send this case back to lower courts to get more evidence. and scott, that would delay a decision in the case until justice scalia's seat is filled. jan crawford at the court night. jan, thank you. today, justice came in two infamous murders near the university of virginia. kris van cleave is at the

disappeared after a concert in 2009. they say it takes a village raise a child. know it takes one to bury a ild. morgan any mother jill, welcomed the plea deal. >> i would say the primary emotion is relief. this has been finding justice for morgan has been a burden on our family for six and a half >> in exchange for pleading guilty, matt to is spared the death penalty. instead he will serve four

the wall in the overpass and exploded into flames. police captain paco valderama. >> he drove straight into the wall there was opportunity to correct or get on the roadway. that didn't occur. >> reporter: the death of the former ceo of chesapeake energy comes one day after department of justice charged him with rigging bids on oil lease is a claim he denied. mcclendon was considered a pioneer in the oil and natural gas drilling business. the boom made chesapeake energy billions of dollars. in 2010, he cold lesley stahl on "60 minutes" that america was sitting on an energy gold mine. >> in

forced out as ceo of chesapeake in 2013. authorities say, mcclendon was going faster than 50 miles an seatbelt. but do not know if the accident was intentional. >> it will take our investigators one to two weeks to completely finish the investigation and re-create the accident. but at this point in time it looks pretty cut and dry. >> investigators have pulled out the suv's black box. scott, they're hoping the box will tell them more about the circumstances of the accident. >> thank you, omar. an urgent call for action next. a government advisory board sounded an alarm about ovarian

surprising gaps in what we know about ovarian cancer starting with the basic definition. though it is called ovarian ovary in the fallopian tubes or uterus. >> these are all tumors. >> dr. douglas levine heads the research lab and was one of the report authors. >> it is a collection of many different diseases. the subtypes of ovarian cancer all occur in or around the ovary, but they have very different origins. >> why is that important? >> when you figure the orgins it tells you information important about treatment, prevention and mechanisms of developing cancer. >> reporter: prevention is key. right now no effective way of finding ovarian cancer early. one reason the disease is so deadly. 34-year-old morgan melnekov, got genetic testing last fall and learned she was at increased risk. >> i was not going to gamble with my life knowing they would early stages. >> so she opted for preventative surgery. in her case that meant removing the ovaries, fallopian tubes and hysterectomy. >> i had to diet. frustrating as a patient. >> you can screen for breast cancer. you can screen for colon cancer. why is ovarian cancer different? >> the cells turn into cancer and spread quickly. we have a limited window opportunity to identify cancer cells. >> often no symptoms or they're vague. here its what alarming. more than half women with ovarian cancer do not get standard of care, treatment by an ovarian cancer specialist. >> dr. jon lapook. thank you, doc. >> today, u.s. and malaysian officials say debris that washed up on mozambique last weekend is believed
