That is the overnight news for this monday. For some, the news continues. For others, check back with us later for the morning news and cbs this morning. This is the cbs overnight news. Welcome to the overnight news, im jeff glor. The first votes will be cast tonight in the race for the white house. The people of iowa will gather in fire houses, church basements, homes and more to caucus. The latest polls show the race tightening. For the democrats Hillary Clinton has a threepoint lead over Bernie Sanders. 45 to 42 . For the republicans in the top with 28 . Is he followed by ted cruz with 23 . And marco rubio with 15 . John dickerson discussed the race with both trump and rubio for face the nation. In iowa, your campaign is based on the idea youre a winner. Does that mean you have to win iowa . I dont have to win it. Right now, you and i are sitting in New Hampshire. As you know, i have a substantial lead in New Hampshire but i think it would be really good to win iowa. Id like to win iowa. Im doing really well with evangelicals in iowa but im also doing tremendously well im doing great with the tea party. Im doing great with all groups. I now have a fairly substantial lead in iowa. I think we have a good chance of winning iowa. Weeks ago it was tighter in iowa. Now youre ahead by a little more. Why do you think that is . I think ted cruz has been severely affected by the Goldman Sachs loans, which he didnt disclose and was on his personal financial form and his citibank financial forms he didnt disclose. Couldnt it be a mistake . Its two loans, give me a break. Hes supposed to be robin hood. Dont forget, he said he sold his assets. Much more important is the whole fact he was born in canada. And he was a citizen of canada until 15 months ago. Theres much law right now and a lot of constitutional lawyers are coming out. Laurence tribe is middle ground, saying its untested. Many top constitutional lawyers are coming out saying ted cruz cant be president because of the fact he was born in canada. I think that has a huge effect. Things, and i talk to people who attend your ral lis and they like youre uncompromising. I also talk to washington insiders, some lawmakers, who are overcoming their skepticism about you thinking hes going to compromise, hell make deals in which is right . I think everyones right. Honestly, i think theyre both right. Im tough to make a deal with. But im a dealmaker. When i see ted cruz standing in the senatat and nobody else is with him, hes standing all by himself, you have all of these other politicians, senators and congressmen generally and hes trying to hes by himself its wonderful. I can understand how a radio show host could say, oh, isnt that wonderful . Not going to get anything done. Have you to get things done. Ted doesnt have an endorsement from one United States senator. He would say thats great because you have said such terrible thinss about them in washington. Theyre not bad people. A lot of are very good people. Some are people that wont get it done. Passeds is a horror show. It is should have never been passed, et cetera, et cetera. When ted doesnt have one senator, like mike lee whos a very conservative guy, good guy, why isnt he getting endorsements . I get the endorsements from sarah palin, Jerry Falwell jr. I have incredible even sheriff joe endorsed me. Those arent senators. Those are no, but still very important people. As an example, sheriff joe, arizona, toughest guy. He endorsed trump. You know what that means . Im toughest on the border. Why do you think have you a lot of working people at your rallies. You have more than any other candidate, you live a life most distant from them. Why do they support you . Because im a job producer. Ive produced tens of thousands of jobs over my lifetime. Right now im producing thousands of jobs. That includes health care, education for families. You know, et cetera, et cetera. Builder in brooklyn and queens. I grew up with people working on houses and whatever. I relate to them. I love those people. Those are my people. I love them. I really do. I love the policemen. I love the firemen. For whatever reason, it is strange even to get to your job, you dont ride three buses and have a second job and all that. No, i have the ultimate bus. Its called a 727. Now its a 757, actually, when you think of it. One of the reasons that ill win and i think none of the other guys will win is because im going to get states that theyll never get. I have a good chance of getting new york, as an example. I have a good chance of getting virginia. Ill get pennsylvania. Ill get ohio. Ill get michigan. Ill get florida my numbers just came down. Im at 48. The sitting senator is at 11 or 12, and a former governor is in the 8s. You may be getting a lot of the lastminute votes going your way. How does it feel . Well, weve always felt great about our campaign here. We continue to feel that its monday night. Ted cruz is clearly the night. He has 10,000 volunteers on the ground. Hes spent an exother tant amount of time here. And has gotten every endorsement he wanted. We know its a tough hill to climb but we feel good about our campaign and very positive about wh
