>> how he escaped with only a scratch. ♪ fireball and on fire. the incredible streak still alive. the warriors' nail-biting win. a double-overtime victory. >> throw it in. >> big hoop dreams with their 28th straight. setting their sights on that legendary record. >> austin takes a 20-second time-out. we're on, ron. we're on. ron is asking, are we on? he's been in television for several decades and doesn't know that when the red light is on, we are on. >> verify it. trust, but verify. >> the red light is on. >> let's do a show. a fascinating new dynamic shipping up in what has been to say least a lively republican race for president. >> political theater at its finest. we haven't seen much of this from donald trump. there is no podium. in iowa, you can see him fielding questions right there from the voters. it was there that he spent much of his time taking on the man who has now emerged as his numero uno contender in that key state. we're talking about texas senator ted cruz. the attacks not as over the top as we have seen in the past. so let's get it out to mary bruce this morning. on the ground in des moines. hi, mary. >> reporter: hi, paula. good morning. it was a night of firsts here for donald trump. he held his first ever town hall here in des moines. and for the first time, took direct aim at ted cruz. >> what a nice job. thank you. >> reporter: this morning, donald trump is soaring in the polls. and drawing new battle lines in the republican race. >> it's not a contest between the two of us just so we understand. >> reporter: jabbing ted cruz for the first time. >> everything i say, he agrees with me. no matter what i say. i do like ted cruz, but not a lot of evangelicals come out of cuba. oil pays him a lot of money. he's got to be for oil, right? the oil companies give him a lot of money. so -- but i'm with you. i'm with everybody. >> reporter: the texas senator is gaining on trump in iowa, where corn is king. >> if ted cruz is against ethanol, how does he win in iowa? because that's very anti-iowa. i don't know how he wins in iowa. i don't know. >> reporter: this farmer tells us, cruz won't cut it here. >> i think if anybody else gets elected, i think it will be a disaster. i don't think anybody else can do it but him. >> reporter: you think it's trump or bust? >> that's what i think. >> reporter: trump says he'll take care of his chief rival. >> will you name him your vice president, or -- or -- >> he's a good guy. he is a good guy. i would say we would certainly have things in mind for ted. [ chanting ] >> all: the people united. >> reporter: earlier, at a lunch in new york, trump took more heat for his call to ban muslims from coming into the u.s. >> all: no trump, no kkk, no racist usa. >> reporter: a clear majority of americans oppose the idea. likely primary republican voters are split. >> right now, i have no problem with that. i like the idea. >> i wish he would focus more on problems with the immigration system in general. >> reporter: now, with 51 days until the iowa caucuses, trump promised he'll spend a lot more time here. joking everyone will be sick of him by then. in typical trump fashion, he also said if he doesn't win here, this will have been a big waste of his time. dan? >> that sounds like a trumpism. mary, thank you. let's get more from matt dowd who is joining us from austin, texas, this morning. matt, good morning. >> good morning, dan. >> so given the vigor with which trump has attacked his other rivals in the past, it seems like, it seems to me like he's handling ted cruz with some kid gloves. what gives here? >> i think it's a couple of things. first, i don't underestimate donald trump's ability to slow ramp up to a high burn. so get prepared. i think he's already started this. it may get hotter later on. two, there's a big overlap between trump voters and ted cruz voters. and so i think donald trump, who is very smart about politics, is aware of that. the third thing is ted cruz, though he's said a few things, has gone out of his way to bear-hug donald trump. so i think donald trump is weighing the best way to draw the contrast. >> all right. let me ask you about a big story that's brewing this morning. republican party leaders appear to be very worried right now about the convention this summer. usually, conventions are simply coronations for the nominee. now there's talk that the republicans may be facing what's called a brokered or a contested convention. what does that mean? >> so i think it's actually better to call it a contested convention. the time of brokers are gone. there's really no brokers in the gop. what that means is no person gathers enough delegates before the convention is held to have a majority. and so that's -- i think the number is 1236 delegates. and so the idea is, nobody gets enough because of how the system works before mid march. i think there is some fear, and some expectation by some, that that may be the case. i think it's a small chance. but it's an increased chance that we're going to see this. and that point is, dan, nobody knows what would happen in the midst of that if nobody goes into the convention with a majority of the delegates. >> it would be history and a full employment act for people like matt dowd. thank you. >> we would love it. we would love it. >> it would be an interesting week. no question about it. matt, thank you. a reminder. on the other side of the race right now. one week from tonight, be sure to watch the new hampshire democratic debate. "your voice, your vote" right here on abc. saturday, december 19th, at 8:00, 7:00 central. paula, over to you. >> thank you, dan. if we're not talking about politics in this country, we're talking about the weather. a lot of extremes. a lot of rarities. here in the east, a lot of us are ditching the winter coats because of record-high temps. if you're in the center of the country, a new storm is about to blast you. with severe weather and snow. rob is tracking it from central park. hi, rob. no coat i see. >> as you said, no coat, paula. it's not required here. you can hear the birds chirping. it feels like spring out here. unbelievable amounts of warmth not just for the east coast, but really for the eastern two-thirds of the country. records are going to fall in many, many cities. look at some of these numbers today. as we pump up the heat. unseasonably warm temperatures. mid 70s. 70 as far north as d.c. 65 new york city. 75 atlanta. tomorrow, we're looking for these numbers to kind of nudge a little bit farther to the east. temps getting over 70 potentially in philadelphia. you see the front, that will be the trigger for some severe weather here beginning early this afternoon. from austin to dallas, up through hopewell, mississippi. we'll get to rounds of weather. another round tomorrow. let's time it out. move it with the clock. we're getting moisture from the gulf of mexico. strong jet stream energy. snow behind this across the inner mountain west. the two bouts of convection will take place earlier today. and then later on tonight, from dallas to houston. and then pushing off to the east tomorrow from shreveport up through paducah and maybe chicago. no jackets required here. i'm breaking a sweat, dan and paula. hopefully, i can come back in the studio where the air conditioning is on. unreal. >> sara speaks bird. and what those birds are saying is, what the heck's going on, marciano? why is it so warm? >> lots of profound stuff going on in the bird speak. >> they are confused. no doubt about it. >> i'm sure they are. get back in here. we'll see you in a couple of minutes. we gotta switch gears now. because there are new developments this morning in the california terror attack. investigators are searching for the killers' missing hard drive. divers pulled objects from a lake that's been at the center of the search. this is all about trying to understand more about the motives of these husband and wife killers. and who, if anyone, may have been helping them. kayna whitworth is on the story. >> reporter: this morning, after two days of searching, fbi investigators are focusing on a hard drive missing from syed farook's home computer, which may contain a trove of evidence about how the san bernardino terror attack was planned and carried out. >> we're searching for any evidence that has to do with this crime. >> reporter: that hard drive, one of the items divers are searching for at the bottom of this lake. >> whether they're able to get all the information from these devices, that's a question as to what type of damage the water has done, and/or, if they tried to damage the devices. >> reporter: overnight, the fbi confirming to abc news, they pulled items from the lake. but cannot verify if they're related to the terrorism investigation. the fbi still questioning enrique marquez. syed's friend and neighbor. whose assault rifles authority say syed farook and tashfeen malik used to kill 14 people. officials say marquez is cooperating. >> enrique was a smart kid. >> reporter: the owner of morgan's tavern, where marquez worked as part-time doorman for three years, remembers him as quiet and polite. >> he checked i.d.s. he had a congenial personality that people felt comfortable around. >> reporter: one of the bar's regular patrons said marquez made allusions about terrorism. >> and he would just talk about, there's so many sleeper cells. and when it happens, it's going to be big. >> reporter: and even bragged about his recent marriage to syed farook's sister-in-law. which authorities say may have been a ruse to help her stay in the united states. >> he said he married her for the visa. >> reporter: marquez worked at morgan's tavern for three years. you might recall it was three years ago, back in 2012, that authorities told abc's brian ross that perhaps marquez and farook were planning something but got cold feet. paula? >> thank you, kayna. terror just on everyone's mind right now. now to gun rights groups planning to stage a mock mass murder near a texas college today. their goal is to wipe out firearm-free zones on campuses at a time when this hot-button issue is on everyone's minds. kendis gibson has the details. from austin. >> help! >> where's the shooter?
