in the race for the republican presidential nomination. romney scored a narrow comeback victory in the michigan primary holding off a strong challenge by rick santorum. in yesterday's other primary in arizona as expected romney posted a convincing win. but romney eeked out a hard fought victory in his native michigan where he and santorum had been running neck and neck. susan mcginnis has details. in northville, michigan. good morning, susan. good morning, betty. mitt romney just narrowly escaped what would have been a very embarrassing defeat here in michigan, his home state. winning here and in arizona gives him new momentum heading into future races and it's calling into question rick santorum's longevity. >> mitt romney moves on with renewed momentum. to next week's super tuesday. >> thank you. >> last night he went two for two. he won the primary in arizona and narrowly defeated rick santorum. in michigan. >> we didn't win by a lot but we won by enough and that's all that counts. >> with two more states in the win column, romney is refocusing his efforts on beating president obama. >> in a second term, he would be unrestrained. by the demand of reelection. we can't afford four years of barack obama with nothing to answer to. >> rick santorum finished in second place in both states. his campaign says the tight race in michigan proves this is a two-man race. >> a month ago they didn't know who we are. but they do now. >> one of the biggest issues for voters was a candidate's ability to defeat president obama. recent polls show in a head to head matchup in michigan, the president would beat mitt romney. >> newt gingrich bypassed michigan and arizona to get a jump-start on the ten states in play on super tuesday. he's looking for georgia to be his first win since south carolina in january. >> the odds are pretty good we'll carry georgia. >> ron paul hasn't won a state yet. >> we're still winning a lot of delegates and that's what counts. >> the gop candidates have to win 1144 delegates to clinch the nomination. mitt romney leads that race. so plan on seeing more of newt gingrich as next tuesday comes close. he's concentrating on super tuesday, especially georgia. betty? >> all right, susan mcginnis in northville. thank you. >> in both states, exit polls show the economy was the number one issue in both states. in michigan, romney scored well with more moderate voters and party loyalists. as reported, romney easily won over michigan voters who said electability was their main concern. he also won among female voters. romney beat santorum among catholic voters in michigan. chief washington correspondent bob schieffer has more on yesterday's election results. >> well, mitt romney said we didn't win by much but we won by enough. which was the quote of the night. that pretty much sums it up. if he had not won, it was a small victory. but let's say he lost by the same margin. he would have had to spend all of the next couple of days explaining why it was as a candidate with the most money with the best organization why it was that he lost in his home state. and there would have been questions. people would have asked look, if he can't win in michigan, where is he going to be able to win down the line. so it wasn't a big win, but it was a win. and winning is always better than losing. now the romney campaign can move on to some of these big states where he'll be contesting on super tuesday, like ohio, tennessee, georgia. you may see santorum do very well in ohio, which is one of the biggest prizes. newt gingrich is concentrating on georgia. but at least mitt romney can now put michigan behind him and move forward. i'm bob schieffer, cbs news, in new york. well, in a surprising move, long time republican senator olympia snow announced she will not seek reelection in maine. snow is abandoning her campaign for a fourth term because she is tired of the polarizing atmosphere in washington. now, this is a setback for republican efforts to regain control of the senate. snow, a moderate was known as an independent voice while serving 33 years in congress. now to severe weather in the plains states. a powerful storm is being blamed for a death in missouri and recover efforts are under way in kansas following an apparent tornado in kansas. reports have surfaced in central kansas but significant damage is reported in the small town of harveyville. that storm struck last night. at least nine people were injured. one man is in critical condition after he was buried under a collapsed home. his own home, in fact. power lines and trees have been knocked down. governor sam brownback declared a state of emergency for the county. meanwhile, another dose of winter weather is moving across the upper midwest this morning. the storm system stretches from the dakotas to wisconsin bringing cold weather and some heavy snow. the storm is expected to dump up to a foot of snow in minnesota, parts of wisconsin and the dakotas. freezing rain is expected to make travel obviously difficult. prosecutors have until tomorrow to bring charges against the ohio teenager accused of opening fire in a high school cafeteria. 17-year-old t.j. lane will probably be charged with three counts of murder. prosecutors say he chose his victims at random. manuel gallegus has the report. an overflow crowd gathered outside the church of st. mary to mourn the deaths of three teenage boys, russell king jr., demetrius hewlin and daniel parmertor. >> the pain is beyond belief. losing a child. >> daniel parmertor's mother first heard about the shooting on the radio. >> i had a sick feeling in my stomach. i didn't know why. i did. i really did. i was scared for him. i don't know why. >> he was funny, lovable kid. >> the suspected killer, 17-year-old t.j. lane, arrived in juvenile court wearing a bulletproof vest. off camera he sat quietly with his grandfather and two aunt and spoke only to say he understood his rights. >> yes, sir, yes, i do. >> the prosecutor said lane admitted taking a .22 caliber gun and knife into the school and to firing ten shots in the cafeteria. >> he chose his victims at random. this is not about bullying. this is not about drugs. this is someone who is not well. >> law enforcement officials say lane will likely be charged as an adult with three counts of aggravated murder. thursday, grief counselors will be at the high school. parents are encouraged to return with their kids before it reopens friday. >> the healing, start the healing process. be with the community and show the support. >> law enforcement officials say the school staff reacted quickly. >> student with a gun. and prevented the attack from getting worse. >> this small, close community is still in shock. manuel gallegus, cbs news, ohio. >> coming up on the morning news, the state of virginia moves ahead with another controversial abortion law. plus, let the rumors begin. it appears apple is ready to unveil the ipad 3. but first, scott pelley has a preview of tonight's "cbs evening news." putting america back to work. how one company is bringing back jobs by taking them from china. that story tonight on the "cbs evening news." what a bargain!
