The states in orange are trumps wins to date. Blue, are ted cruz. Two term governor. John kasich won his first only primary last night. His home state ohio. But apparently, the showme state, missouri, didnt see enough last night. They cast 1. 5 million votes. Both trump and cruz and clinton less than 2,000 votes each. Too close for an official result yet. Even so, cbs news estimates that trump now has more than half the delegates he need for the nomination. Heres major garrett. This was an amazing evening. Reporter the swing state split decision witled the field to three candidates. While we are on the right side this year. We will not be on the winning side. Reporter after losing in his home state. Marco rubio dropped out. Trump is on pace to win. Ted cruz and john kasich said they will fight for delegates to the end. Only two campaigns have a plausible path to the nomination. Ours and donald trumps. Nobody else has any mathematical possibility whatsoever. It is unlikely that anybody is going to achieve enough the gop frontrunner issued this predicts if he doesnt get the nomination at a contested convention. I dont think you can say that we dont get it automatically. I think you would have riots. I think you would have riots. Reporter this morning, former House Speaker john boehner floated another idea. Draft current speaker, paul ryan. His spokeswoman shot that down quickly saying he will not accept a nomination. Committee chairman Reince Preibus told us. There isnt going to be a game played where some one goes into the convention with majority of delegates and some how now that person is not the nominee. I dont see that happening. Reporter delegates are bound to their candidates for the first ballot. Preidus acknowledged the party can rewrite the rules at its discretion. I can imagine that the nomination rules would have to be looked at. Obviously. Second, third ballot type rules. You wouldnt have contemplated in the last convention. The now threeman race was headed for a primetime debate monday. Trump and kasich pulled out forcing its cancellation. The night before contests in utah and arizona. With 98 delegates at stake. Major garrett, thank you. You probably remember the tense moment saturday when a man rushed donald trump. Well today that man, thomas demassimo was charged with a federal crime, entering a secret service restricted area. Now to the democrats, Hillary Clinton won at least four more states last night. She now has nearly 2 3 of the delegates she need for the nomination. Here is nancy cordes. Thank you, North Carolina clinton had more thanking to do than her own campaign had expected. She swept four states by as much as 31 points. A feat sanders did not acknowledge at his rally. Important election. We will win. Reporter in a statement the vermont senator insisted he is still on a path to win the nomination. And that the primary calendar favors us in the weeks and months to come. But, thats also what he said before last nights blowout. In a memo today, the Clinton Campaign laid out the odds against sanders. Nearly half of the remaining pledge delegates are in just three states. California, new york, and pennsylvania. Senator sanders would have to win them by 20 points. And rack up a string of victories just to pull even. In short they argued, clintons delegate lead is nearly insurmountable. We are moving closer to securing the Democratic Party nomination and winning this election in november the clinton camp knows there is a fine line between confidence and arrogance. They say they will not be but it is his decision. Scott when she faced a similar choice in 2008, clinton stays in all the way to the end. Nancy cordes, thanks. Now with confidence and not a hint of arrogance well turn to john dickerson, our cbs news political director and anchor of face the nation. Trump lost a big one in ohio last night. How damaging was that . Well not winning the 66 delegates means trump has to du better in the future. Before last night he had won 44 of the delegates now. He need to win 52 of the remaining delegates. Up for grabs. But, rules in later contests give winners a greater share of the delegates. That will help him and there was evidence last night, particularly in florida, where he got 48 of the vote, that his results improve as the field shrinks. So he has shown capacity to do better in the future. Now if republicans wanted to deny trump the nomination is there a way they could do that in the coming contests . Delegates to deny him the majority of delegates. That means beating him outright in the states where they are winner take all. He may be weaker, montana, nebraska, south dakota. In the states where he is strong. That distribute delegates proportional. They have to come in close second to shrink the delegate prize. That is going to be hard to do. Kasich and cruz, keep splitting the nontrump vote. Maurko rubio dropped out last night. The face of the new Republican Party. Hispanic, young, what happened. He was selling the wrong product. That youth, that outreach expansion to new voters and that optimism. It was a year when voters wanted a champion for their anger. And also, his greatest legislative achievement, pushing a comprehensive Immigration Reform bill, thats part of what had stirred up that voter anger in the first place.

And her campaign this morning, wont describe her lead as insurmountable. They do point out it is twice as large as president obamas ever was. In 2008. Thank you florida. Thank you ohio. As clinton celebrated sanders didnt even mention his losses to a crowd. More than 7,000 in arizona. But, he made it clear, he plans to go on. Phoenix, are you ready for a Political Revolution . According to cbs news exit poll results, voters in all five states said clinton would make a better commanderinchief than sanders. And that her plans are more realistic. Every candidate owes it to you to be clear and direct about what our plans will cost and how we are going to make them work. Thats the difference between running for president and being president. [ cheers and applause ] reporter the sweep was a huge relief for clinton who openly worried earlier in the day that voters were getting complacent. People think they know who is going to win. They may not be turning out. We cant afford that. The surprise loss in michigan may have given them the volt they needed. The wins in ohio and illinois will blunt sanders argument clintons strength is largely confined to the south. 2 million more votes nationwide. She is now nearly 2 3 of the way to the democratic nomination. And had harsh word last night. There is great anger for the likely gop nominee who was just a few miles away at maralago.

Gop frontrunner donald trump is warning of riots around the Republican National convention this summer if he is denied the nomination. Trump now has more than half of the delegates he need to become the nominee. And he said he follows a couple votes short and the convention decides on some one else there could be trouble.

Candidates believe they have a pathway to getting to majority of delegates before cleveland. We will be ready for anything. Reporter sources tell cbs news officials in the rnc, donors as well as the candidates, john kasich and ted cruz. Help is on the way. Are already planning for the possibility. Today the Democratic Party is the party of the American People. Traditionally Political Parties have a clear nominee let me make one further i accept your nomination. I proudly accept your for the presidency of the united states. Donald. Learn not to interrupt. The campaign defied the rules. At contested convention, delegates submit bal lots until some one wins a majority. There can be multiple round of voting. First round, delegates are bound by the results of their states primaries and caucuses. Once you get into additional rounds. Delegates no longer have those obligations and could throw their support behind some one who never officially entered the race. Campaigns will be working behind the scenes to shift delegate support. Some times that means candidates are jockeying, you know for the months leading into the convention. The last time the Republican Party held a convention without a clear nominee was 1976. Gerald ford beat out former governor Ronald Reagan on the first ballot to secure the nomination. Political historian says an open convention brings with it the risk of creating a deeper divide within the Republican Party. Its hard for me to believe that Trump Supporters are just going to allow some kind of deal making to go on between the other candidates. The cbs overnight news will president obamas nomination of Merrick Garland to fill a vacant seat set off a firestorm of controversy. Senate republicans insist they wont hold hearings on the nomination much less give garland an up or down vote. The next term of the Supreme Court could face cases involving health care, immigration, climate rules, and gun rights. And it is the constitutional right to bear arms that has a their ground. We have two reports on this. Starting with Anthony Mason and the Second Amendment. At the heart of the debate over guns in america, is a single inscrutable sentence. The Second Amendment of the bill of rights. The wording itself is unusual. Isnt it . Its unusual, its short, its clogged with commas. Reporter Michael Waldman heads bren noncenter for justice at New York University law school is author of a biography of the Second Amendment. The Second Amendment says, a well regulated militia, being necessary to the security of the free state, the right of the people to keep and bear arms, shall not be infringed. What does that mean . Reporter the most disputed clause in the constitution is the phrase about militias which were of great concern when the bill of rights was written in 1792. At the constitutional convention, in philadelphia, there was a very big controversy about how to al low military power. Professor of constitutional says the states fear the new government would try to disarm the 13 state militias which required every white male over 16 to own a musket. They were very worried the states were deprived, would be deprived of their purr to resist federal tyranny. The militia is our safety. Patrick henry argued. We can hatch no security without it. While guns were common place then. So were gun regulations. New york and boston, prohibited the firing of guns within city limits. And in the notes for the constitutional convention, waldman says. There is literally not a word about it protecting an individual right for gun ownership for self protection, hunting, or any of the other things we think about now. There is one side that believes that this amendment refers specifically and only to militias. Well, i know people say that. If you look at what the words say. Yeah. It says the right of the people to keep and bear arms. It does not say the right of the states. Or the right of the militias. It says the right of the people. The debate over the Second Amendment came to a head here at the Supreme Court in 2008. In a case filed over the capital gun laws, called district of columbia vs. Heller. In a 54 vote the court affirmed an individuals right to keep and bear arms. Striking down d. C. s ban on handguns in the home. The inherent right of selfdefense, Justice Antonin Scalia wrote in the majority opinion has been central to the Second Amendment right. But scalia added, the right is not unlimited. Also, leaving room for gun regulation. Area. It is absolutely a continuing gray area. Absolutely a continuing gray area. Another gray area. Is how the court might rule on future Second Amendment issues. After the sudden death of judge scalia in february. So. You know. A lot depends on, on on who replaces justice scalia. Most people who live in urban areas cant imagine why anyone would need a room full of rifles and handguns. For millions of americans who live in the wide open spaces firearms are a way of life. Heres ted koppel. Reporter if you ever wondered where the deer and the antelope still roam, this is it. It is still a storybook west, you know to so many people. Reporter the big fellow, looks like he has been riding all his life and bears a striking resemblance to teddy roosevelt, thats bob modell. Few miles outside of cody, wyoming. Boys those are some of bobs ranch hand getting ready to feed the horses. When they head up into the mountains they will be carrying rifles for, protection against wolves and coyotes or to put down a horse thats broken a leg. Even down here, a couple of the men carry handguns. Will you never know when you may need it. Reporter it is an enormous piece of land. Modell owns 5,000 acres and then there is another 195,000 acres of public land surrounding his ranch. So you are sitting on roughly 200,000 acres of my land. I am. Well you are welcome. I appreciate that. I would say to you i am a good steward. I use it for grazing my livestock. And i am also, a licensed big game outfitter. And youre lucky to have me, you know, watching after your you know when when people who dont hunt look around a place like this and when you see all of the head up on the wall, they say, what the hell is that guy talking about . Conservation, theyre killing them. Hunters played an Important Role in conserving not only wildlife, but, our resources upon which the wildlife live. There is no getting around it. Guns are big in wyoming. More guns per capita than any state in the country. As for the residents of park county, thats where cody is located, well, heres the sheriff, scott stewart. If they have guns in the home. Low end will be four to five. High end is going to be anywhere from 100 to more. And how many people in those counties do not have guns . I would say that, a very minority. Still when it comes to the rate of gun related murders, average. Share stewart will tell you he is all right with all those guns out here. A handful of deputies. Some times, you have a deputy on one side of the county. Get a call. 40 miles away. Chances are he is not going to get there to intervene in any conflict that is maybe going on. What you are telling me is people need to be able to take care of themselves. Absolutely. Guns are woven into the tapestry of all of the old wyoming families. That, of retired senator, Allen Simpson for example. How long have you simpsons been out here . Great grandfather came to jackson in 1884. My grandmother lived to be 100. She was born in salt lake in, in 1874. Two years before the custer battle. She always carried a derrigner in her purse. First. The senators son. With his son. Mack. They call him, big mack. Does this sort of match what your dad did with you, i mean, what al did with you . Absolutely, ted. What i am doing here with the boys is exactly what we did. There is a real effort to instill gun safety. People in other places dont understand how careful we are. How much we understand and how we learn from a young age. Age 13. Dillon ramero is a crack shot. An expensive sport. His father had him draft a contract outlining what he is prepared to do in order to keep shooting. Keep a gpa, 3. 95. Not do any drugs or alcohol. Ever, pretty much. And just stay out of trouble with the law. My teachers. Respect him and my mom. Dillon started shooting when thats how old ella is now. But she and her dad bo allen have already been at this for a while. What is the first time you shot a gun . I think when i was 5. You are an old hand. Doing this a long time. You like coming out shooting with your daddy . Yeah. Respect starts now. Respect of life. Respect of country. Respect of game. Everything starts now. That all starts. When theyre impressionable. Haley. Haley, turn around so you can see the camera. I want to know one thing. Did you have a good time. Did you enjoy this . Would you like to do it again . At this point, some gun control advocates in our major heads in disbelief. Folks out here though, couldnt care less. They dont give a [ bleep ] what people think about them back there. While theyre killing each other every day more than they are out here. Why do we have to listen to that . Out on a pheasant shoot says collin simpson, says people and their guns get along just fine. A community event. A family event. The memories that i have, with my father and my brother and my two boys, and my wife and my, my, i mean you name it. Those are wonderful memories.

Garland joined the federal Appeals Court in 1997. Liberal who builds consensus. Before becoming a judge, he spent much of his life in public service. His tenure at the Justice Department was defining. He supervietzed the prosecution of the 1995 Oklahoma City bombing. We promised that we would find the perpetrators that we would bring them to justice and that we would do it in a way that honored the constitution. He says thats at the core of his believes. Fidelity to the constitution and the law has been the cornerstone of my professional life. If the senate sees fit to confer to the position for which i have been nominated today i prop is to continue on that course.

Senator sanders would have to win them by 20 points. And rack up a string of victories just to pull even. In short they argued, clintons delegate lead is nearly insurmountable. We are moving closer to securing the Democratic Party nomination and winning this election in november the clinton camp knows there is a fine line between confidence and arrogance. Calling on sanders to drop out but it is his decision. Scott when she faced a similar choice in 2008, clinton stays in all the way to the end. Nancy cordes, thanks. Now with confidence and not a hint of arrogance well turn to john dickerson, our cbs news political director and anchor of face the nation. Trump lost a big one in ohio last night. How damaging was that . Well not winning the 66 delegates mean trump has to do better in the future. Before last night he had won 44 of the delegates now. He need to win 52 of the remaining delegates. Up for grabs. But, rules in later contests give winners a greater share of the delegates. That will help him and there was evidence last night, particularly in florida, where he got 48 of the vote, that his results improve as the field shrinks. So he has shown capacity to do better in the future. Now if republicans wanted to deny trump the nomination is there a way they could do that they have to win enough delegates to deny him the majority of delegates. That means beating him outright in the states where they are winner take all. He may be weaker, montana, nebraska, south dakota. In the states where he is strong. That distribute delegates proportional. They have to come in close second to shrink the delegate prize. That is going to be hard to do. Kasich and cruz, keep splitting the nontrump vote. Maurko rubio dropped out last night. The face of the new Republican Party. Hispanic, young, what happened. He was selling the wrong product. That youth, that outreach expan tugs new voters and that optimism. It was a year when voters wanted a champion for their anger. And also, his greatest legislative achievement, pushing a comprehensive Immigration Reform bill, thats part of what had stirred up that voter anger in the first place.
