captioning funded by cbs it's wednesday, march 16th, 2016. this is the "cbs morning news." a three-man race. donald trump stacks up victories in the republican chase for the white house, knocking marco rubio out, but john kasich's win in ohio puts a new obstacle in the billionaire's path to the nomination.

huge drives towards becoming the democratic nominee winning four of the night's contest and closing in on a sweep. commuter chaos in the nation's capital. washington, d.c. shuts down its subway system for an entire day with little notice to hundreds of thousands of passengers. and the madness begins. three weeks of basketball mayhem hits off with the first of 67 ncaa tournament games. good morning from the studio 57 newsroom at cbs news headquarters here in new york. good to be with you. i'm anne-marie green. well, the morning after critical presidential primaries in five states, hillary clinton has solidified her grip on the democratic nomination. while the republican race seems headed to a convention showdown. donald trump scored big wins in at least three states, including a blowout in florida, and is resist neck and neck with ted cruz in missouri.

to bernie sanders, taking at least four of yesterday's contests and is winning narrowly in missouri, a race that is still too close to call. thanks to last night's victories, clinton picks up 400 new delegates and gives her 1,500 to date which is two-thirds of what is necessary to secure the nomination. don champion is following the democratic race in miami. don, good morning. >> reporter: good morning, anne-marie. certainly the kind of night the clinton campaign needed after that shocking loss to bernie sanders in michigan last week. clinton rebounded, once again, be handing the vermont senator some heavy losses in the south, while also slowing some of his momentum in the midwest. >> this is another super tuesday for our campaign. >> reporter: hillary clinton scooped up delegates all over the map. her biggest victories in florida and ohio. in florida, where more than half

50, clinton won handedly, getting more than three-quarters support. concerns over her past view on trade deals did not seem to hurt her in ohio, where she won amongst voters making less than $50,000 a year. >> our campaign is for the steel worker i met in ohio on sunday night who is laid off but hoping to get back to work. >> reporter: clinton once again received overwhelming support from minority voters, getting more than 70% of the hispanic and latino vote in florida. voters in all five states believe she has a better chance than sanders of winning the general election. clinton turned her attention to the gop front-runner. >> when we hear a candidate for president called for rounding up 12 million immigrants and banning all muslims from

he embraces torture, that doesn't make him strong, it makes him wrong. >> reporter: despite his setbacks, sanders remained undaunted. >> she has a super pac where among other special interests have received $15 million from wall street. >> reporter: looking ahead at the upcoming calendar, sanders believes the votes in the west will be favorable to his campaign, but as clinton proved last night, she is capable of winning around the map. >> don champion in miami, thanks - back to the republicans now. as major garrett reports, it was a big night for donald trump, but not everything he hoped for. >> reporter: despite wins in florida, illinois and north carolina, donald trump did not land the knockout blow that would made him the presumptive nominee.

john kasich won and making a contested convention in cleveland more likely than not. >> all i can say is thank you from the bottom of my heart, but i want you to know something, we are going to go -- we are going to go all the way to cleveland and secure the republican nomination! >> reporter: it was kasich's first primary win and last stand. he said a loss in his home state would have ended his campaign. he won with a late surge of support from moderates and voters who made up their minds the last few days. yesterday did end the campaign of florida senator marco rubio. >> while it is not god's plan that i be president in 2016 or maybe ever, while today my campaign is suspended, the fact that i've even come this far is evidence of how special america truly is. >> reporter: it wasn't supposed to be this way for rubio. once described as the republican savior, rubio was crushed by trump in his home state.

trump has a solid lead in delegates and despite what has been a nasty personal campaign, says he is looking forward to unifying the republican party. >> we have a great opportunity and the people that are voting are democrats are coming in, independents are coming in and very, very importantly, people that never voted before. it's an incredible thing. >> reporter: so far, trump's closest competition has come from texas senator ted cruz. he finished close to trump in north carolina. >> god bless the great state of north carolina. >> reporter: where he spent time and money. >> every republican has a clear choice. only two campaigns have a plausible path to the nomination -- ours and donald trump's. >> reporter: there are now three republican candidates left in a race that looks like it will continue all the way to cleveland in july. major garrett, cbs news, palm beach, florida.

than 600 delegates pst of the 1,237 needed for the nomination. though there are more than a thousand delegates up for grabs, any kind of run by cruz or kasich would deny trump an outright victory. cbs news political and "face the nation" moderator john dickerson says kasich's win in ohio will slow down trump but it's still not clear if it will matter in the end. >> the question on the republican side is whether that speed bump grows into something more. for those who have been a part evident anti-trump movement they see glimmers of hope that they can deny donald trump the number of delegates that needs, 1,237, to get the nomination before the nominating convention in cleveland. in they can deny him that number, then they can work it out in cleveland and have a fight either among ted cruz, who is second in the number of delegates accumulated, or perhaps maybe a long shot spot for john kasich. we will see how much they can

john kasich in the days going forward. for hillary clinton, on the democratic side, it was a big win in two different ways. one, she added to her already dominate delegate lead with the big victories, particularly in florida, but also for her, she was able to win to the states that give her momentum, not only winning in the south but also in ohio. so more contests to go for both parties probably still all the way into june. for cbs news, i'm john dickerson in new york. coming up "cbs this morning," we will have more on the possibility that donald trump is headed to a contested convention in july. president obama could announce his nominee to replace antonin ska calia on supreme court as early as today. the first indian american could
