Reporter trump in florida tonight, where theres a by lingual battle to deny him a win. Florida senator marco rubio, his campaign on life support the only thing that could save him a home state victory. Were going to get elected president and were going to turn this country around. Reporter but today, rubio saying his Campaign Goes on, even without a win tonight. Well, our plan is to continue forward in this campaign, as i said. My campaigns never been built on winning in one particular state. Tom, a lot of eyes on john kasich in ohio, as you know. If he wins, could help slow down trump . Reporter thats right, david. Even if donald trump wins florida tonight, but he loses ohio, its going to be much harder to wrap up this nomination, and it could possibly lead to a contested convention come july. David . Tom, well see you a bit later. To the democratic side tonight. Can Hillary Clinton lock in the nomination or at least get far closer, or is there a sanders surprise brewing like michigan .

Her sights set on the crucial battleground of ohio. Clinton telling me, shes optimistic about the night ahead. But not confident . Supporters might want to hear you say. Okay, im confident. I think optimistic is basically the same thing. Im confident. I feel very good about the campaign. Reporter is tonight the night you could close this deal . I feel good about where we are and i think at the end of the night, well end up, again, significantly ahead in delegates. Reporter but when i pressed her you lose the midwest tonight, do you still declare victory . You know, you keep asking me these questions, which ive answered repeatedly. I will end up this evening with more delegates. This is about delegates. Reporter for Bernie Sanders, everything is on the line. Hes outspending clinton in state. Good morning. Reporter but the vermont luck. He needs delegates. How are you feeling about tonight . Reporter clinton already looking ahead to the general election and donald trump. When you are inciting mob violence which is what trump is doing in those clips, theres a lot of memories that people theyre in the dna. People remember mob violence that led to lynching. Reporter trump says he hasnt even started to hit clinton yet. This could be a general campaign that is very ugly and very personal. Does that give you any pause . No, not a bit. Reporter your face doesnt even move. No, not a bit. He can run whatever kind of campaign he wants. I have really thick skin and its not about me. Its about every american and what were going to do together. Cecilia with us live tonight, as well. Cecilia, we saw there, she said shes feeling optimistic. You pressed her, is she confident . She said yes there, but what are inside the campaign . Reporter well, david, they are realistic about her chances in the midwest, especially in ohio, where they expect Bernie Sanders to do well, especially with young voters and white voters there. But look, they are hoping to win in North Carolina and here in florida, where they are hoping to have a big Victory Party tonight. David . Cecilia, thank you. Hour. Five key States Holding primaries. But as we pointed out, the stakes enormous in ohio for both parties. Lets get right to george, who will lead our coverage in primetime tonight, and george, the front panel of the cincinnati inquirer. The words ohio, its up to you. So, george, what happens if donald trump wins in ohio, what happens if he loses . David, its a president ial election, it is always up to ohio, no question about that. And tonight is no exception. If donald trump wins tonight, winner take all in ohio, he has a big lead in florida, as well. He will have the argument that hes won the biggest states, got the most delegates and the momentum. Hell have a real shot of wrapping this up before the convention in cleveland. If he loses, if he doesnt get the 66 delegates, he is going to need to get 60 of the delegates Going Forward in order to wrap up this before the convention. The olds of a contested convention go way up. It will be hard to see how any of the candidates remain in this race can get the delegates they need before cleveland. In the meantime, on the democratic side, george, how important is ohio for hillary if she wins ohio tonight on top of North Carolina and florida, shell have a huge delegate lead. Almost insurmountable. If she loses, even though she may still add to her lead tonight, she will be signaling weakness in a state that democrats need to win come november. All right, george stephanopoulos, thank you. Well see you just a few hours from now in primetime. In the meantime, we want to get to jon karl, because jon, you are seeing ing ing Something Else in the exit poll day ta data .

You see 27 of Republican Voters today say they would not vote for donald trump in the fall. In the general election. The key thing here is, though, look at the other candidates.
