Transcript for Donald Trump Fights Backs in New Hampshire
Tonight the rice to the primaries in New Hampshire is intensifying and it's a war of words between the gop candidates. With the stakes higher than ever trump is doubling down and rousing his supporters. Some showing their support in ways they can never take back. Here's ABC's David Wright. Reporter: Only one candidate here in New Hampshire is doing well enough to rate at the clay dragon tattoo parlor in Seabrook where the owner bob Holmes is doing trump tattoos for free. This is not your first trump tattoo? No, this is my 27th. Reporter: It's a painful reminder of the passion trump supporters feel for him. Anybody getting Ted Cruz tattoos? No, no. Marco Rubio? No. Jeb bush? No. Reporter: Trump as nearly as much support as his next three rivals combined. He'll be center stage at Saturday's ABC news debate. The next president of the United States -- Mr. Donald J. Trump! Reporter: Today he told a town hall in exeter he's looking forward to the debate because his opponents seem to be dropping like flies. Whittling down rapidly, right? Rapidly. Which is good. We have more time to speak. Reporter: His supporters sure think that's a good thing. He's what we need. This is our last chance for this country to get back to being great again. Reporter: Even his opponents can't seem to get enough of him. Over here you've got all the people that are hoping to get into the rally. Over there are the protesters. Look at the range of causes. Palestinian rights, nuclear weapons, protect our wildlife, gay marriage, students against bigotry, all looking for a little bit of attention from Donald Trump. Please join us in welcoming secretary Hillary Clinton and senator Bernie sanders. Reporter: Tonight for much of the democratic debate -- Enough is enough. If you've got something to say, say it directly. Reporter: Hillary Clinton and Bernie sanders for once did their best to ignore him, instead focusing on each other. One of us voted the right way and one of us didn't. Reporter: But out on the campaign trail, he commands more than his fair share of attention. We love you, Donald! Thank you! Make this country great again! Reporter: From the grounds and the the cameras. He's a polarizing figure but draws support from both ends of the political spectrum. I have met a lot of republicans that are fed up, they felt they lost twice in a row and they shouldn't have. I met a lot of democrats, I remember a family in Iowa said to me they were very proud to vote for Barack Obama, and it's the biggest regret of their life. Reporter: ABC news off-air reporter John Santucci has been to almost every trump rally. You can call it a movement, call it a silent majority awakened, he's hit a nerve. If it's a movement what's the movement for? I think it's a movement to basically just blow everybody out. Reporter: When I first met Donald Trump, this time last year -- What's the argument for a trump candidacy? Well, I know what I'm doing. I'm a very capable person. Reporter: Nobody would have predicted he'd eventually be the front-runner. But already he had his platform in place. We have to clean up our border. We have to strengthen the border. . We have to build a wall. Nobody can build like trump. We need a wall. Gold-plated wall? We need a wall that's going to keep people from just walking in like they're doing right now. A message he rode almost to victory in Iowa. We finished second and I want to tell you something. I'm just honored. Good shot! Reporter: The Friday before the caucuses trump sons invited reporters out for an informal session of pheasant hunting. Doesn't Ted Cruz have the duck dynasty vote locked down? I was with Willie Robertson and his brother Jason and Phil last week. Willie came out and endorsed us. Reporter: I asked Donald and Eric Trump how well their dad could handle defeat. There's an impression out there that your dad might be a sore loser. If he loses Iowa, things might come apart at the seams a little bit. Do you think that's fair? I think we're going to win Iowa, I think we're going to win by a lot. He wants to be a guy who wins. Is it hard if you ultimately lose? Sure, anybody would take a knock. I think there's going to be a lot of candidates who are going to be very upset coming out of Iowa. But I think we win, I think we win by a lot, I think we win nationwide, ultimately I think we take the nomination. Reporter: Ever since narrowly losing there, trump has transformed. First he was gracious -- I want to congratulate Ted and I want to congratulate all the incredible candidates. Reporter: Ever since he arrived here it's a new ball game. First spinning defeat as victory. I think we did really well. We did really well. Reporter: Now he's attacking the Iowa winner, Ted Cruz, outright. By doing what he did to Ben Carson, that was a disgrace. Reporter: Accusing him of dirty tricks in robocalls like this to Iowa precinct captains. This is the Cruz campaign with breaking news. Dr. Ben Carson will be planning to Sa suspend his campaign following tonight's caucuses. Reporter: Cruz has said this. When you win in the state of Iowa, your opponents want to tear you down. They want to attack you, they want to throw mud. Over the course of your career there have been famous quotes about success and failure. Some of them not so flattering about failure. Some of them not so flattering even about second place. Which of them best applies to what happened in Iowa? I just think -- I'm happy with the way we're doing. I just want to continue to do well. Our theme, the theme is so important. It's just, make America great again. That's what we're going to do interior make America great again. A slogan you see all over the place in New Hampshire. Most unexpectedly at that tattoo parlor in Seabrook. Today 19-year-old Stephanie conner is getting trump's campaign slogan tattooed on her ribs. You must really like Donald Trump. Yeah. What do you like about him? What I like about him? The way he wants to fix this country. Make things better. I've been covering politics for a long time -- I don't think I've ever seen something like this. You're killing me. I bet you're wishing his slogan was "Yes, we can." Yeah, right? The rest of her life she'll have this souvenir of the 2016 campaign. A most unusual race I'm mortalized in indelible ink. I'm David Wright for "Nightline" in Seabrook, New Hampshire. You do not want to miss the last gop debate before the new Hampshire primary this Saturday night right here on ABC.
