now we'll turn to some insight from anthony salvanto, our cbs news in-house expert on delegate math and all of the rules of primaries and caucuses. anthony, looking forward to tomorrow, if donald trump wins florida and ohio, will his nomination be inevitable? >> he'll be all but certain, scott. he won't clinch, but he'll have a commanding lead in delegates and be in a commanding position to get the rest he needs, first because the rules now start to change. the way that states give out winner-take-all contests tends to favor the leader and make it harder for trailing candidates like cruz and kasich to catch up burke 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 blue collar suburban republicans that are voting for him already. so the thinking will go: if they can't find a way to stop him tomorrow, in places like florida and ohio, it's hard to see how they suddenly find a way to stop him at all. >> pelley: now, what happens tomorrow if trump w

anthony salvanto, our director of election, thank you, anthony. on the democratic side, it was a sanders sweep this weekend, bernie sanders won the contest in washington state, alaska and hawaii, picking up 55 delegates, but he is still far behind hillary clinton, who already has 72% of the delegates she needs. the republican governor of georgia broke with his party today, nathan deal vetoed a religious liberty bill that many considered anti-gay. it would have allowed religious organizations to refuse to perform same-sex marriages and to fire anyone who violated their beliefs. several large companies including coca-cola and disney threatened to boycott georgia had the bill become law. a teenager who campaigned against gun violence is its and honoring the women helped america win a war when the "cbs evening news" continues. it just kinda like...wiped everything clean. 6x cleaning my teeth are glowing. they are so white. 6x whitening i actually really like the 2 steps. step 1, cleans step 2, whitens. every time i use this together, it felt like... .

now we will turn to anthony salvanto, our cbs news director of elections, our expert on the delegate count. anthony, you've been looking at whether trump can be deprived of the delegates he needs. >> it won't be easy, scott. trump's delegate lead gives him the clearest path to winning the nomination outright this spring, before the convention. he needs just over half the remaining delegates. now, you compare that to ted cruz, who would need about 80% of them, and that's a tall order. especially because trump keeps piling up republican votes. so far he's collected more than two million more than ted cruz. that's why, scott, all the talk now is of slowing trump down, keeping him from getting the rest of the delegates he needs but not necessarily overtaking him. >> pelley: when will we know? >> the big tests start next week when april's primaries kick off in wisconsin. then we head on to the northeast, where big delegate- rich states like new york and pennsylvania hold their primaries. trump is expected to do well there. but if he stumbles, he'll need to pick up about two-thirds of the d

joining us now is cbs news director of election, anthony salvanto. we're going to try to map out the next week. let's start first, one thing i found interesting in the poll was john kasich challenging trump in ohio doing much better than rubio in his home state of florida, why is that? >> one is home state advantage one may be disadvantage. in ohio say economy is good and kasich has sky high approval ratings as governor. that's an advantage. but comparably in florida rubio's approval rating as a senator are mixed. even among republicans he's got lower numbers than rest of the candidates on being prepared to be president and that's essentially the difference. >> dickerson: all right. let's talk about ohio and florida. big winner take all states next week. let's go through some of the scenarios here. it seems like for the moment given where donald trump has been the question is, is he going to get enough delegates to get the nomination or will he go to the convention with maybe a lead in the delegates but have been stopped. let's walk through some of t
