this is the "cbs evening news" with scott pelley. >> pelley: good evening. it is a new reality for republicans after the closest iowa caucus in history, and who would have guessed? in december, rick santorum was polling at 4%, but last night he virtually tied mitt romney for the win, losing by eight votes out of more than 122,000 cast. it was a record turnout. michele bachmann, who won the iowa straw poll this summer, dropped out today after finishing sixth. the ink was barely dry on the ballots when the candidates moved onto new hampshire, where the primary is next tuesday. a suffolk university poll out today gives romney a commanding lead in new hampshire, 43% to ron paul's 14%. newt gingrich is third, rick santorum fifth. our campaign 2012 team is in new hampshire tonight, and we'll start with jan crawford on the romney campaign. jan? >> reporter: well, scott, romney went into conservative iowa, and his victory there is a remarkable turn of events for a candidate who had all but written off that state just a few months ago. >> my goodness, what a squeaker! but it sure is nice to have a win, i'll tell you. >> reporter: romney won iowa with a good strategy. >> thank you, iowa. >> reporter: for months, he had downplayed expectations, but after seeing competitors like newt gingrich fade and hold, including his own, indicating he could finish strong, last week romney went all in. he toured the state with his wife ann while he and other candidates and their super pacs blanketed the airwaves with tough ads aimed mainly at gingrich. >> newt has a ton of baggage. >> reporter: romney won on the issues voters say they care about most. among those who said beating obama was most important, 48% voted for romney, far above the other candidates. he also won voters who picked the economy as their top concern. he flew to new hampshire today to keep his momentum going, and to pick up the endorsement of senator john mccain, his 2008 opponent. in that race, mccain complained about romney's negative ads. we asked mccain about similar complaints this time from gingrich. >> i think candidates always complain. you don't like to see that kind of thing. unfortunately, it is what it is today, particularly with these outside "super" pacs. >> reporter: now, romney has some money and the organization for the long haul, but so far he has not been able to excite the conservative republican base. now, here in new hampshire, where voters very much are in his favor-- he's speaking right now at a packed town hall-- that might not be a problem. but going forward to south carolina and beyond, scott, it could be. >> pelley: new hampshire, right next door to romney's home state of massachusetts. jan, thank you very much. despite that new hampshire poll that we just showed you, romney says he expects rick santorum to put up a fight there. bob schieffer spoke to romney in iowa today for bob's new web show called "face to face." >> rick santorum spent a lot of time, as you know, here in iowa. he's going to now have to build that support elsewhere. but i don't think he's at ground zero elsewhere. he's been working those other places, he's got good support. >> reporter: our election polling unit tells us that support for santorum came from the rural counties of iowa. mitt romney won in the bigger cities. santorum worked the hardest in iowa. with more than 300 appearances in all 99 counties, and having lost by eight votes, he must have wished that he had stopped just one more place. bill whittaker is with the former pennsylvania senator tonight. bill? >> reporter: scott, rick santorum just arrived here in new hampshire. with the primary less than a week away, he knows he must keep up his momentum, beef up his organization and increase his cash flow. >> game on. ( cheers and applause ) >> reporter: even rick santorum staffers were surprised by his near victory in iowa. the trip to new hampshire today was more than a journey of 1,300 miles. the former pennsylvania senator was transported to a new political reality-- from also- ran to real contender to man of the hour. >> with your help and god's grace, we'll have another fun night a week from now. god bless you. ( cheers and applause ) >> reporter: his success in iowa was a combination of hard work, visiting all 99 counties, and good luck as other candidates rose and then fell from favor. but his real strength: born- again christians. they made up 56% of iowa caucusgoers, and santorum won a third of them. but in new hampshire in 2008, only 21% of g.o.p. primary voters called themselves born- again christians. bartender john lewis is a christian values voter. >> right now, if he can garner more support, you're going to see a cascading flow of money come to him. if that happens, he could win the nomination. >> there's a town hall meeting. >> reporter: staffers admit he must broaden his appeal and fatten his coffers. his war chest going into the fall: just $1.3 million, versus mitt romney's $32 million. and with romney 37 points ahead of him in the polls, state campaign co-chairman william cahill says his candidate will need every penny he can get. >> he came into this campaign with a three-state strategy: to get out of the gate in iowa, new hampshire, and onto south carolina. that's the focus right now. the fundraising i know will pick up after last night. >> reporter: but in order to keep the money and momentum going, he knows he must do well here in new hampshire. so, scott, santorum plans to spend every day here in the state between now and the primary. >> reporter: bill, thank you very much. newt gingrich's support collapsed under the weight of those millions of dollars in attack ads that jan crawford was telling us about, and ads sponsored by supporters of romney and ron paul. but today gingrich punched back, and dean reynolds is with the gingrich campaign in manchester, new hampshire. dean? >> reporter: scott, within hours of his fourth place finish in iowa, newt gingrich was arguing forcefully that mitt romney's victory there was really not that big a deal. >> and the fact is, three out of four republicans rejected him. governor romney is... is a moderate massachusetts republican to the left of the vast majority of republicans. >> reporter: gingrich underlined that point with a full page ad today in new hampshire's largest newspaper. >> i find it amazing the news media continues to say he's the most electable republican when he can't even break out in his own party. >> reporter: national polls show romney slightly ahead of gingrich, but gingrich suggested romney has hit a very low ceiling-- always somewhere in the 20s nationwide and not improving. >> it becomes more and more obvious that people go to anybody but romney. >> reporter: it's all part of a strategy to raise doubts about romney here, weaken him to the point that a victory will seem unimpressive and give him no spring board to south carolina. in the most recent poll taken in mid december, gingrich was ahead in south carolina, where he's well organized and spoiling for a fight on january 21. his aides admit he must win there to stay in the race. romney supporters are already running close to a million dollars' worth of ads attacking gingrich in both south carolina and florida. last night, gingrich seemed annoyed when he congratulated rick santorum for his race in iowa but pointedly ignored romney, who won. >> i'm wondering why. ( laughter ) >> i know that's a rhetorical question, and a good one. >> reporter: he also suggested romney, a former massachusetts governor, was not up to the job of president. >> if you want to truly change washington, d.c., somebody who failed totally to change boston may not be the right person. >> reporter: now, the gingrich campaign, scott, does not regard the underfunded santorum or the libertarian ron paul as serious contenders for the nomination, and the former speaker expects that over time some supporters of michele bachmann will come his way because he's more in tune with them than romney. >> pelley: dean, thanks very much. as we mentioned, texas congressman ron paul is polling second, but a distant second in new hampshire. his support last night came from young people and from first-time caucus voters, people who said that the federal budget worries them the most. rick perry came in fifth in iowa, and last night he said he was reconsidering his campaign. but today he said he's staying in, and he'll focus on south carolina. joining us now for some insight into all of this is bob schieffer, our chief washington correspondent and anchor at "face the nation." bob, you can't make too much of the results from one state, but what does it mean when you have two republicans who are so different in a dead heat? >> well... and don't forget you have ron paul in there, too, scott, because what you have here, you have mitt romney, who got about a quarter of the vote-- that's what he keeps showing up in the national polls-- but you have two conservatives who got about, you know, twice as many votes when you put the two of them together. that is coming from very conservative voters. still, coming out of iowa with the win, as mitt romney has done, i think he is feeling very good about his chances now. and the reason he is feeling that way is, i don't think he thinks that ron paul is going to wind up getting the nomination, number one. he's just so far to the right of the mainstream of the republican party. and when you look at it here, romney has more money, he has better organization, he is the one that is in the best position now to last through the long haul. i think that's why they feel pretty good about it in his campaign, and frankly i think that's why it's going to be very difficult to keep him from getting the nomination. i think he's the one to beat right now. >> pelley: bob, thank you very, very much. how getting a job may have saved one man's life, a report card on america's war on cancer, and the lost world discovered deep below antarctica-- when the "cbs evening news" continues. and these come together, one thing you can depend on is that these will come together. delicious and wholesome. some combinations were just meant to be. tomato soup from campbell's. it's amazing what soup can do. what's going on? we ordered a gift online and we really need to do something with it... i'm just not sure what... what is it? oh just return it. returning gifts is easier than ever with priority mail flat rate boxes from the postal service. if it fits, it ships anywhere in the country for a low flat rate. plus i can pick it up for free. perfect because we have to get that outta this house. c'mon, it's not that... gahh, oh yeah that's gotta go... priority mail flat rate shipping starts at just $4.95. only from the postal service. a simpler way to ship and return. have given way to sleeping. where sleepless nights yield to restful sleep. and lunesta can help you get there, like it has for so many people before. when taking lunesta, don't drive or operate machinery until you feel fully awake. walking, eating, driving, or engaging in other activities while asleep, without remembering it the next day, have been reported. abnormal behaviors may include aggressiveness, agitation, hallucinations or confusion. in depressed patients, worsening of depression, including risk of suicide, may occur. alcohol may increase these risks. allergic reactions, such as tongue or throat swelling, occur rarely and may be fatal. side effects may include unpleasant taste, headache, dizziness and morning drowsiness. ask your doctor if lunesta is right for you. then get lunesta for $0 at lunesta.com. there's a land of restful sleep. we can help you go there on the wings of lunesta. i just transferred a prescription to cvs, because they have care 1 on 1. that's where the pharmacist stops and talks to me, about safety and saving money with generic prescriptions. laura, let's talk about possible side effects. it's all about me. love that! get care 1 on 1, only at cvs pharmacy. we accept express scripts and 5,000 other insurance plans. ♪ i'm laura, and this is my cvs. it's all mine. flavor, meet food. introducing swanson flavor boost. concentrated broth in easy to use packets. mix it into skillet dishes, for an instant dose of... hell-o!
