Now we will turn for insight to Anthony Salvato cbs director of elections expert on delegate math and all of the rules of the primaries and caucuses. Anthony, looking forward to tomorrow, if donald trump wins florida and ohio, will his nomination be inevitable. He will be all but certain. He wont clinch but a commanding lead in delegates and commanding needs. First because the rules now start to change the way that states give out delegates with more winner take all contests, tends to favor the leader and make it harder for trailing candidates look cruz and kasich to catch up. But more than that, trump will also be heading into a map beyond tuesday that should favor him politically. There will be contests in the northeast in the west. Places that are full of the kind of bluecollar, suburban republicans voteding for him already. So the thinking will go if they cant find a way to stop him tomorrow, in places like florida, ohio, hard to see huh what happens tomorrow if trump wins florida, as seems which is possible. Jut right. Thats what his opponents, cruz and kasich are hoping for. Slow him down if not to catch him. A glimmer of hop to those who want to see this process go on.

Since september, russian war planes have pounded opponents of syrias assad dictatorship turning the tide of the 5yearold civil war. With russian air cover, assads forces have captured considerable territory from the rebels. A partial ceasefire has reduced, but not eliminated the fighting. The ceasefire does not apply to isis, which still controls about a third of syria and iraq. Including the city of mosul with nearly 2 million residents which has been cut off from the world since isis took over in 2014. Well, tonight. Into what is happening there. Outside of mosul. She met refugees who risked everything to escape. It is close to midnight on the front line just outside mosul. And these kurdish soldiers are hundreds of yards into nomans land. So some one coming .

He told us three men were caught escaping just a few days ago. And isis hanged them in the street. Theyre a criminal gang cried and we have been surviving on water and bread. Is there any sign that isis is getting weaker . When they first came, they were tough, said this man. But now they can see that mosul is turning against them. The men told this a plan to fight against isis themselves now theyre free. And to smuggle their wives and children out of mosul as soon as they can. This was just one night on the front line. But what we heard suggested people in mosul are growing increasingly angry with isis. And scott, that could make retaking the city a little easier.

But the campus is in an uproar after the team captain was expelled. Jericka duncan is looking into this. When the yale bulldogs celebrated on sunday they were missing star point guard jack montague.

Scott, i will tell you on the what we are seeing here is a changing of the guard. If trump wins the nomination for the convention and looks like he probably will it is going to turn the Republican Party on its ear. If it goes to an open convention, it will be a bloody fight that could break the party into two parties. And in either case, Republican Party scott, that we used to know it, will be replaced by something new, exactly what that will be, is uncertain. And that is the scariest part of always bodes ill in politics, matters is just that. Do you think trump could win the presidency . He could. Historically, nominees from outside their Party Mainstream do poorly when republicans split over civil rights in 64. Nominated barry goldwatt r they want down to historic landslide defeat. When democrats kicked out Party Regulars and nominated george state but massachusetts. Under the old rule, scott, what this is coming down to is basically a couple of very flawed candidates.
