Donald trump is competing statewide hoping to trigger a winnertakeall majority. Hillary clinton is fighting to hold onto her double digit lead, while Bernie Sanders takes a day off the campaign trail for a really big trip. Nbc news political director and meet the press Moderator Chuck Todd joins us now. Lets start with Bernie Sanders trip to the vatican. Did that sway in voters in new york . You i think that its hard to i dont think the event had the impact here that i think maybe they thought it could have at this point. Whats interesting is so he jetted off to rome. Shes jetting off to california for a fundraiser. Neither one of them are in new york today. Were calling it a critical primary, like, well, how critical is it . And actually i am starting to question that. I think a week ago Bernie Sanders wanted to make this a bigtime primary. I think both cruz and kasich were hoping to show that trump would show weakness in new york and the fact of the matter is the two new yorkers that more call it home than anybody else in clinton and trump, it looks like theyre going to win with a comfortable majority. They sure had a testy debate last night. Who would you say won . They did, and i think status quo favors the frontrunner. In many ways i give Bernie Sanders credit for realizing it was a do or die moment. He left it all out there. He threw everything at her because the only shot he has up today and you told me Bernie Sanders is the democratic nominee, there would only be two things i would have assumed to have happened. One, he pulled an upset and beat her in new york and then it sort of changed the narrative or some outside force, maybe the email investigation sort of caused her a problem. Thats the only two paths for him. So losing new york and i think thats why he threw it all in there, if it goes to what we think, its hard to see where the sanders path goes from here. Donald trump has called the wall street Journal Editorial Board is bunch of dummies, called for them to be fired. I wake up this morning, hes got an oped in the wall street journal. So what gives here . Well, look, its been a remarkable tenday stretch for donald trump. Think about where we were, the wednesday after wisconsin. Boy, it looked like his campaign was reeling. This antitrump movement looked like it had juice. Ted cruz had won by double digits and there was questions, boy, maybe he can be kept under 50. Brings in some new hands, the new team and the old team seem to be working together better than you think. Donald trump is actually keeping the same message for three days in a row. The oped that you referred to is all about whats interesting here is they have a message that they want to send which is they believe that any attempt for somebody else to win this nomination is a is somehow a theft of trump and is somehow stealing the nomination from trump. I think this week hes laid that groundwork pretty well and its put the rnc on the defensive, ted cruz on the defensive. Its been a remarkable turnaround for trump in nine days. Hes turned around and hes looking for president ial. Gee said he could do it like that. The thing is he can do a lot of things like that, and thats always been the longterm concern, why theres been so much trepidation about sort of going on getting on board the trump bandwagon. What do you have coming sunday . Were going to have both party chairs, reince priebus, Debbie Wasserman schultz. Theyre both perhaps preparing for contested conventions, and then the exclusive with the North Carolina governor pat mccrory who has been in a firestorm, lgbt law there. So First NationalTelevision Interview and he will be in studio in d. C. Sounds good. Thank you, chuck. You will want to tune in not only this weekend but every sunday morning. Chuck todd hosts meet the press at 10 30 right here on nbc 4. Speeding has become a pretty big problem along a busy highway in alexandria. Residents say its putting their lives in danger when they try to cross it. Were talking about the stretch of the George WashingtonMemorial Parkway near bellhaven road along the potomac river. Derrick ward joins us live now from alexandria with a look at what police are doing to try to slow drivers down. Derrick . Reporter that is the whole idea of it. Now, were here at bellhaven road. This is also known as the m of things going on here. Folks trying to get off bellhaven heading north or south on the parkway and people coming off the parkway trying to get onto bellhaven as well, all with no light. Only a stop sign. And people say, well, you add speed in there, it gets particularly dangerous. So u. S. Park police announced today they are mounting an effort to try to make it a little bit safer. If you havent taken a pleasurable ride along the mt. Vernon parkway, you have missed one of the areas most scenic drives. Its best taken in at a safe speed though. Posted speed. Sound advice, especially now. Youre going to see an enhanced presence on the south end of the George Washington parkway and well be looking for people speeding. Reporter the posted limits vary from 35 to 45 miles an hour. Usually we have people going 55 and sometimes 60. Reporter thats a problem because through here at the intersection of bellhaven road and mt. Vernon parkway youre cutting through a residential area with people trying to get shores 69 potomac. Right now were going to cross to go to the parkway and go for a walk, but it also makes you nervous because theres no pedestrian crosswalks. Reporter its a place where drivers and pedestrians have to take special care. Its unforgiving to those who dont. We see a lot of car crashes involving property damage, minor injuries, even a fatality last year. The black suv, 46 miles an hour. 654. 1 feet. Reporter some in the area are happy to seethe enforcement area but put less faith in the overall effectiveness. David has had some close calls of his own. Truly believe we need two Traffic Signals put in. Reporter but on a parkway thats not likely anytime soon. This is a more likely deterrent. Ten miles over the speed limit can get you a 95 fine. And that can go up over 300 very quickly. Reporter but, again, thats only if youre driving very quickly. And police say goal is to get people to slow down. They dont really want to pull folks over. You got no shoulder on a lot of this parkway and, of course, with the move over law, that makes it a bit of a challenge for traffic all the way around. So they really hope that presence makts peopes people sl. Live in alexandria, derrick ward, news4.
