Youve been doing the math, how might this play out for trump and his rivals . Lets start with what the delegate count is going to look like after super its over here on the board over here.

And then he has a chance to accelerate it, and essentially two weeks later. How does he do it . If he wins all of these winner take all states, by beating kasich, all delegates in florida by beating delegates. Basically halfway to the magic number of 12 1237. However, if john kasich can beat trump in ohio and marco rubio can beat trump in florida, look at how the delegate map changes. We did the math here. What does this mean, lester, is the bottom line . Theres two scenarios left in the republican nomination race. Donald trump wins this nomination by march 15th, were headed to cleveland in a contested convention. There is no other scenario. All right. Chuck, thank you. High drama tonight in the battle between apple and the fbi. The company filed a motion today to throw out a judges order for it to help the fbi killers. Saying the feds are seeking a dangerous power, all of it as apple insiders say the company is now working on a new version that would be impossible to unlock by anyone but the user. Our justice correspondent Pete Williams has details. Reporter apple has always made security a selling point. These are the new iphones. Reporter when it released the iphone 6, snowden was warning about government surveillance, apple made a point saying it would no longer help police get information out of the new phones when they were locked, even when served with a search warrant. Now apple is trying to make the phones more secure, working to develop an iphone that cannot be unlocked by anyone but the user, not by the police, not even by apple itself. Its fighting the fbi which wants apple to modify the software in the phone to disarm the security and let agents try to unlock an iphone used by one of the San Bernardino attackers. The fbi director told lead that must be pursued. We must do a competent investigation following the murder of 14 people in San Bernardino. And well use whatever lawful tools are available to us. Reporter apple said the fbi is trying to force it to create a brandnew version of the iphone by changing the software, and it says the government cannot do that. You cannot ask a private citizen to create a product for it. And it cannot ask apple to change the iphone in ways that was never intended to be used or to be employed in. Reporter apple today told a judge in San Bernardino that what the fbi wants would create a back door, leaving personal information vulnerable to hackers, identity thieves, hostile foreign agents and unwarranted government surveillance. Next week both apple and the fbi will face off in a hearing on capitol hill. They both say it should be up to congress, not the courts, to settle this fight.
