Transcript for Gov. John Kasich: 'I'm considering' running for President, taking it 'very seriously'

winner in Ohio is Mr. Bush. Crucial state in presidential politics. No Republican has ever been elected without the state of Ohio. The state of Ohio is going to Barack Obama. The most campaign events by both candidates in Ohio. It was as fiercely contested a state as we had in the nation. Donald Trump wins the state of Ohio. One of his core four. You've seen it right there. A big victory for Donald Trump. Ohio always such a key in presidential races. We're going to start with the governor of Ohio, Republican John Kasich. Governor, thanks for joining us. Thank you, challenge. I'll start out with some congratulations with the Buckeyes big win over Michigan. You'll be out of office in a few wins. You ran for president last time around. You ran back in 1999 as well. How seriously are you thinking about taking it on this time? Very seriously, George. These are earnest conversations that go on virtually every day with my friends and family. We need different leadership. There isn't any question about it. I'm not only just worried about the tone and the name calling and the division in our country and the partisanship, but I also worry about the policies. The rising debt. The inability to deal with immigration. The problems we have as America alone in the world. What I consider a rotten deal with the Saudis to look the other way. These are things, George -- I'm worried about our country, not just in the short term. I didn't mean -- I'm worried about our country in the long term. The question for me is what do I do about this? Is it -- you know, what exactly -- do I run because I've determined that I can win? Or is it important for me to make such a good showing that I can send a message that can disrupt the political system in this country? I have to think about it. I think about it seriously. As you know, I still travel. I'm out there trying to do what I can do. I don't know when I will have to make a decision, but let's not -- let's be clear, I'm not being coy. I'm just trying to do this for some kind of -- it's not a game. This is serious for me. You're up against a formidable challenge. You complained in New Hampshire that the Republican party has been hijack by president trump. He's got about a 90% approval rating inside the party. Does a challenge inside the party have any practical chance for success? All options are on the table for me. Let me ask you a statement -- let me ask you to think about this. At what point does somebody stand on principle and say the direction we're going is wrong? You want to be able to make a statement. Maybe I do that by running again or, you know -- frankly in the last election I was the last man standing with very little money and very little name recognition. It grew over time. What I ask myself is what do I owe my country? What can I do to help my country? Is this -- does it mean -- do I run for office again or are there other ways I can impact the flow of events? I listened to the last interview with the senator. I thought she did a very good job. It's the same old stuff. It's the politics and mumbo jumbo and we this and that deal. We've got to get out of this mire and it's going depend on raising the public to say we deserve and want better. I don't know where it's all going to lead, George. It's a serious consideration every day. Does better mean working across party lines? You talked about running on a bipartisan ticket. Including perhaps with governor John hickenlooper. Is that something that's truly viable? Is that what you think Americans are looking for? George, I don't know that -- let's say that Donald Trump is nominated and Elizabeth Warren is nominated and you have this ocean of people in the middle. Is there a legitimate opportunity for a third party to be able to score a victory or have a profound impact on the future of American politics? That would be something I would talk to you about off line and get your view. We don't know at this point. Everybody's looked at it in the past and said it's not possible. You've seen it before and there seems to be a ceiling. You know what, no one thought a guy like Donald Trump would be elected president. No one thought we would have electric cars. No one thought we could talk on phones and see the person we were talking to. This is a time of change. You've can't change tomorrow based on today. Hickenlooper, love him, but the name is too long. You couldn't fit it on a bumper sticker. You have your Ohio colleague Sherrod brown coming up next. He's a Democrat. You can't both be from the same state. That's out of the question. Do you have a time table? I don't. We have to see how events develop. The whole top of your show is about what is likely to happen. We don't know what is going to happen. What we think is going to happen tomorrow never happens tomorrow. It's so different. I have to see what makes the most amount of sense for me personally and the people around me. That's what I gotta do. Is it fair to say if Robert Mueller comes out with more indictments and as Allan Dershowitz said a devastating report for Donald Trump that would open up a path for you for a primary challenge? George, there's all different things that can develop here. As you know in politics -- that's why we love politics. What we know today is not necessarily what we see tomorrow. We sit. We plan. We raise a little bit of money. We keep my team together. I learned -- I spend my time working on the issues. I want to finish as governor strong. This was a heck of a year for Republicans in Ohio. I think the road map I laid out with my team, which is no one gets left behind. We cut taxes for those at the top. We also provided the first income relaxation provisions for people at the bottom. We can make sure no one is left behind. We expanded medicaid so the mentally ill and drug addicted could get help. No one is left behind. The top, the bottom, people feel they can participate. It showed in Ohio where it didn't show in others. It's a road map, not just for Republicans, but Democrats as well. Governor Kasich, thanks for your time. Thank you George.
