Frontrunner from trump tower in new york. And ed henry is at the Hillary ClintonConvention Headquarters and molly lion in pennsylvania and jays rosen is in maryland. Lets start off with what the exit polls are telling us so far. Martha mccallum is here to break it down for us. Were talking with voters tonight in three of the five states as they leave the polling places. Weve got connecticut, maryland and pennsylvania polls this evening. People are still out there voting. An early look at what theyre telling us. First up, republicans, this week kasich and cruz announced an alliance to try to keep donald trump from getting to the 1237 delegate number. Were going to be seeing if that made a difference in any of the votes this evening. Late deciders, those who decided in the past week, leaning towards governor john kasich. Heres connecticut, these numbers are also pretty tight with him, towards the front in pennsylvania and in maryland as well. Plus, about a quarter say that their vote was mainly against the other candidates, rather than in support of anyone in particular. Cruz and kasich voters are much more likely to say that their vote was placed against another candidate. Look at the numbers, connecticut 24 , 25 say it in maryland in pennsylvania, its 18 . Almost all of the Trump Supporters new york city big surprise here, say that they placed their vote in favor of their candidate. Donald trump. So thats said, about one in four republicans say they would not vote for donald trump if he ends up being the nominee. When you look at group of people who are nonTrump Supporters, those voting for kasich or cruz, more than half of them say that they would not place a vote for donald trump. To the contested convention, republicans believe if nobody hits 1237, the party should nominate the candidate who has the most votes in the primary. 66 feel that way in maryland. About the same in connecticut. And pennsylvania as well. More than 9 in 10 of trump voters say that they firmly believe that the gop should nominate the person who comes into that convention with the most votes. Not necessarily a majority, 1237, but the most votes. While about half of the nontrump voters say the opposite. They say let the delegates decide. On the democratic side, as usual, sanders is doing well as he does in all of these contests so far, with young people and very well with independents as well. Black voters, seniors, breaking for Hillary Clinton this evening in the early going and the numbers that weve got, large majorities in each state say if push came to shove, they would vote for either Hillary Clinton or Bernie Sanders as the nominee. They are pretty happy with most choices, most think its clinton who has the best chance to defeat clump if he becomes the nominee. Back to you. Well for donald trump, a big night tonight, keeps him mathematically alive to win the nomination outright before the convention. And thereby sidestep what could be a nightmare scenario for him in which he loses on a second or third ballot in cleveland. Chief Political Correspondent carl cameron is in trump tower right now. Trump is trying to keep his momentum rolling. Five states with 118 bound pledged delegates available. For the winner across the board and trump is looking to get between 9095, a big number. In addition there are 54 unbound delegates, unpledged delegates out of pennsylvania. Hes eyeing somewhere in the neighborhood of twothirds of that. If he pulls it off, he can clinch the nomination. Before he has to go to cleveland and the actual convention. Trump is looking to sweep all five east coast states, but still complains that the process is crooked. Its a scam, its a rigged system. Promises by trumps new campaign bosses that he would clean up his act after last weeks new york landslide have not been realized. This was last night in wilkes bri berry. Heres a guy who says im going to stay, like if you have a child who is a spoiled brat. Where they go i dont care, daddy. Get out of the room, daddy. Trumps restored power to Campaign ManagerCory Lewandoski after his recently hired adviser Paul Manafort was recorded suggesting to rnc officials that trump will be more president ial. Senator ted cruz attributes trumps advantages in todays east coast voting states to shared liberalism. They tend to be more on the liberal side of the spectrum. He may have a good night. Right after tomorrow the race is going to shift back west and as it shifts back west there are a lot of states that i think are going to be very good. Particularly indiana next week, a mustwin to stop trump. Cruz slammed trump for his criticism of carrier air conditioners, located in indiana for planning to move jobs overseas where regulatory costs are lower. Donald says im going to punish carrier, im going to use the force of the federal government to punish any company that flees the regulations of the federal government. Thats exactly what barack obama says, its exactly what Hillary Clinton says. Thats what Big Government liberal does. Cruz says hell implement policies to encourage manufacturers to return to the u. S. Not punish them. The kasich Cruz Alliance to try to stop trump in indiana, new mexico and oregon is still very much in play. It could be expanded to include california. In the meantime. Kasich is being accuse of dissolving the alliance almost immediately because he refuses to urge indiana voters to vote only for cruz. He says he Wont Campaign there, he wont spend money and resources, just as cruz wont in new mexico and oregon, he refuses to be the candidate to urge voters to vote for somebody else and hes getting badgered by reporters for it. Carl cameron, just around the block at trump tower. Hillary clinton is hoping to virtually seal up the democratic nomination tonight. Chief White House Correspondent ed henry is at clinton headquarters in philadelphia right now. Megan, good evening. The good news for Hillary Clinton is shes coming to philadelphia with the nomination, all but hers, the bad news, Bernie Sanders is showing almost no sign that hes willing to work and help elect her in november. Hillary clinton is so confident of victories in the five Eastern States that today she jumped ahead to indiana. Which votes next tuesday. To show its full speed ahead. As president i will go to bat for all of our trades. For our steel workers, our iron workers, everyone who is absolutely looking for that kind of champion. While it was perhaps one last stand for Bernie Sanders. Campaigning here in philadelphia, at the redding market. Sanders bristled at questions about whether hes going to drop out. Vowed to fight on to california on june 7th and chafed at clinton boasting last night on an msnbc town hall that shes wrapping this up. Well sanders was reacting to clinton being defensive about her lead, even though shes winning. But i am ahead and lets start from that premise. While we talk about what happens next, okay . Clinton seemed to lose her cool. As Rachel Maddow tried to ask whether she would press sanders to get out of the race if hes clearly behind after california. If youre ahead in the vote, if youre ahead in delegates. I am ahead in the vote. I am way ahead in the vote. Look, i have the greatest respect for senator sanders, but really what he and his supporters are now saying just doesnt add up. I have 2. 7 million more votes than he has. I have more than 250 more pledged delegates. That came after sanders blew off a question about whether hell get his supporters to rally around clinton, if shes the nominee. Putting the onus back on her. Were not in a movement where i can snap my fingers and say to you or anybody else, what you should do. And if secretary clinton wins, its incumbent upon her to tell millions of people who right now do not believe in establishment politics now the tension continued late today when the sanders camp put out a harsh fundraising letter, showing clintoned a Donald Trumps wedding and charging that the clinton camp has been using language to attack sanders thats normally reserved for quote traitors. Tough stuff, megan. What do you make of whats happening tonight. The five primaries in which donald trump looks well positioned. The cruz camp, kasich camp says youve got to look beyond tonight this thing is not over. Your thoughts . Well, thats true. Even if theres a trump sweep tonight. As it seems possible there will be. Theres two races going on. Trump is running to win the nomination outright. The other two are running to deny him that win. Neither of them can win it outright, theyre mathematically ruled out. Theyve got a somewhat easier task. They just have to hold him to under 1237, hes trying to get there. And obviously, he cant get there tonight, and theyre hoping that if they can deal him a blow next week, out in indiana, that it will make it very hard, hed have to have a completely massive sweep in the remaining states to get there. Hes likely to take a big step forward tonight and theres no getting around that. Hey, brett, what about the momentum . And if he has big wins tonight and heading into indiana, no matter what happens there, lets say he comes up short by 50 to 100 delegates by the 1237, by the end of california. How much does that momentum heading into the Convention Get him the additional delegates . I mean there are all kinds of estimates, is it significant . Bret, think of it this way, trump has been held under 50 everywhere until last week. In the voting percentages. He won by a distinct majority last week. It will be important to see what kind of majorities he rolls up tonight. If he rolls up big majorities in three or five of these states, that may indeed generate momentum. His opponents have been saying the guy is getting half the delegates, but only got 38 or 40 of the vote. That will begin to change if he rolls that up tonight. I think it gets harder and harder to stop him even if hes headed off into indiana and doesnt quite get to 1237. I dont think when you get to the convention, if hes close, that the party as a whole would want to risk alienating his voters by denying him the nomination or refusing to come up with the delegates to give it to him. Because they cant afford to lose the number of voters they think they would lose if it had looked like he had been cheated. Well be back to you in just a bit as our special coverage continues tonight. A new York Supreme Court judge has ruled that a fraud case against donald trump over his former school, will go to trial. The new York Attorney general accuses now Defunct Trump University of using what he calls baitandswitch tactics. Trump has denied wrongdoing. His legal team is seeking a jury trial. Possibly in the fall, and says trump could testify. There are a few downballot races well be keeping an eye on. In maryland, democratic congressman Chris Van Hollen and Donna Edwards are fighting it out to win the nomination for novembers election to replace retiring senator barbara mikulski. Voters in baltimore are choosing a new mayor. In pennsylvania, former congressman joe sestak rematch with pat toomey in the fall. Focused on the election here at home, north korea is getting ready for a nuclear test. Were told it could happen any time and represents another escalation in the communist countrys nuclear saga. Rich edson is live at the white house. North korea continues testing Ballistic Missiles, continues to develop its Nuclear Weapons program. The Administration Says the United States will continue to bolster its defenses in that region as president obama acknowledges such a volatile regime is a massive security challenge. North korea, a Nuclear Country with an erratic leader is threatening to attack the United States and its allies. Pentagon Officials Say there are indications north korea is preparing a fifth nuclear test. Its fourth was in january. Defying u. N. Security council resolutions, they continue to test Ballistic Missiles, apparently launching one saturday from a submarine. The administrations response . Sanctions and Missile Defense. Even as we try to resolve the underlying problem of Nuclear Development inside of north korea, were also setting up a shield that can a the relatively lowlevel threats that theyre posing right now. The Obama Administration and longtime ally, south korea are, negotiating a plan to deploy a Ballistic MissileDefense System on the korean peninsula. Though even with Missile Defense and international sanctions, one regional analyst says the u. S. Needs a more aggressive strategy to deter north korea. The administration has put in place Security Council sanctions, china is implementing them more than before. Although there are loopholes, its kind of late. Republicans have moved to north korea sanctions bill through congress. And say it is up to the white house to address the regimes continued aggression. I think weve acted. It would be nice to see what the president had in mind beyond that. The president is quite confident in the defense capabilities we have to protect the american people. And to protect our allies in the asia pacific. It means we need to continue to monitor the threat thats emanating from north korea. It means we need to be nimble. And adjust our strategy accordingly. But there has been a significant commitment of resources. China says it is firmly opposed to any u. S. Missile Defense System on the korean peninsula. The Administration Says it is reassuring the chinese that that system is only design dodd keep north korea in check. Meg megan. What does north koreas continued aggression mean for the u. S. . Syndicated columnist Charles Krauthammer joins us from washington. Your thoughts . It seems to me the big threat is not necessarily their new test, their nuclear test. Theyve had them. They have nukes, obviously. Whats really worrying, the doomsday scenario is they miniaturize a warhead, they put it on a missile and the worst part is what we just saw the announcement, were not sure if it was real event or not. But if they can launch it from a submarine, that means they become invulnerable. You put a missile on a submarine, somewhere in the oceans, it cannot be found. And that means they would pose a perpetual threat this is why we have our nukes on submarines. Lurking around the world, near our shores that could hit the United States. Right now it needs a longrange missile to hit a city in the u. S. Youre in the submarine, you dont need that. Thats a threat and thats why the fact that the democrats have fanatically opposed Missile Defense until very recently, all through the 80s and 90s, after reagan had proposed it, is the reason that we are way behind where we ought to be. Yes, we have to build up our nuclear Missile Defenses. But we are way behind and we have to do it. Especially if they go to submarines. The charles, the next president , whoever he or she is, is going to face a dangerous world. Saturday they had the submarine test by north korea. Then you have last week iran conducting a longrange rocket test. Something to put a satellite into space. China conducts a test, launching a new longrange Ballistic Missile last week. And russia tests a new intercontinental Ballistic Missile, using hypersonic glider technology, thats all within a week. Look, i think history will remember the Obama Administration for a few things. One of them will be, that it did nothing in fact, it facilitated proliferation in an age when we cannot afford it. The russians and the chinese, we can handle that. Theyve had nuke force half a century. And we have deterred them. The iranians could be undeterrable and obama has been the facilitator. They will go nuclear within a decade. There is nothing in the agreement that will stop that. And the north koreans, every Administration Since the 90s has not succeeded in stopping them. But at least we ought to be developing our defenses. The fact that they are on their way, they are completely undeterrable. As are the iranians. Means that were going to be entering an age where theres no security in deterrence. Its going to have to be in defenses. Charles, thank you. Were just getting started. In our special night of election coverage. Will donald trump make a clean sweep tonight . Rocket towards the republican nomination . Or can cruz and kasich hold him back . When we come back, other news, including one of Hillary Clintons almostforgotten emails about benghazi. Theres only one egg that just tastes better. So fresh from the farm. Delicious. Perfect.
