else who's thinking about getting in the race. michael bloomberg. you said yesterday, "i love it," speaking about him getting in the race. why would you love it? >> well, i would love it. i know michael very well. i'd love to compete against michael. and i know him very well. and i think he might very well get in the race. and i would love to have him get in the race. >> one of the reasons -- >> he's very opposite on me with guns and he's opposite on pro life and he's opposite on a lot of things. so i would love to have michael get in the race. to do it, but i hope he does. i would love to compete against michael. as for the democrats, iowa has tightened to a tossup. our battleground tracker shows bernie sanders is up over hillary clinton 47% to 46%. in new hampshire sanders has a comfortable lead, 57% to 38% for clinton. but in south carolina it's all clinton. she leads sanders 60% to 38%. sanders sat down with john dickerson for "face the nation." >> the cook political report looked at the rest of the states after iowa and new hampshire and found they didn't have as many liberals as in those first two states.

distance even if you win in iowa and new hampshire? >> well, john, let me just say that the poll in south carolina was 60-38. if that's the case, it is showing us making huge, huge gains. and i feel confident that if we can win here in iowa, if we can win in new hampshire, and those are going to be tough races, i think we stand an excellent chance to win in south carolina and in nevada. but if you look at the polling recently, and i can tell you because i have been to south carolina. we have a lot of momentum on the ground. i think we're picking up more and more african-american support. frankly, i think we can win there. >> you have a new ad out this week which is you and the simon & garfunkel song "america." what does that ad mean for you? >> what that ad is about is to talk about the fact that as we come together as a country, and we have so much strength, so many extraordinary people, that

there is nothing we cannot accomplish. we are the wealthiest country in the history of the world. we should not have massive levels of income and wealth inequality, the highest rate of childhood povertiy, the only country on earth that doesn't guarantee paid family and medical leave. and when we come together -- that is what it is. it's a beautiful song, and i think the photography is beautiful. let us stand together and tackle the real problems facing our nation, and we can accomplish enormous things. >> here's how bill clinton characterized your campaign. he said, "this other guy's madder than she is," referring to his wife, "and that feels authentic. and besides, his slogans are easier to say." your reaction. >> well, i am angry. and the american people are angry, john. people are angry because they don't understand why they have to work longer hours for lower wages and almost all new income

1%. they are angry because their kids are leaving school $40,000 or $50,000 in debt. and they're angry because they are seeing the united states having a nation in which elderly people are trying to make it on $12,000, $13,000 a year on social security. people are asking why. the country is angry and i share that anger. >> the cbs overnight news will be right back. laundry can wreak havoc on our clothes, ruining them forever. sweaters stretch into muumuus. and pilled cardigans become pets. but it's not you, it's the laundry. protect your clothes from stretching, fading, and fuzz. ...with downy fabric conditioner... it not only softens and freshens, it helps protect clothes from the damage of the wash. so your favorite clothes stay your favorite clothes. downy fabric conditioner. wash in the wow. when heartburn hits fight back fast tums smoothies starts dissolving the instant it touches your tongue at the source

here's the keys. mate. hm, wouldn't mind some of that beef wellington... to see how much you could save on car insurance, go to geico.com. zah! (car alarm sounds) it's ok! as president obama enters his final year in office, he is also looking back. first run for the white house and sat down with the president for "sunday morning." >> it is such an extraordinary privilege to have this job. and look, there are times where you get tired. there are times where you're frustrated. >> you wonder why you did this? >> absolutely.

that i have not walked into the oval office and understood that at no point in my life will i ever have the chance to do as much good and make as much of a difference in the lives of people as i do right now. and that's precious. so i'm going to try to squeeze every last little bit of good work that i can while i still have the chance. >> if you're looking for the world's best cars and the workers who make those cars, you need to be in detroit, michigan! >> reporter: the president's visit to detroit, we are toured the north american international auto show this past week, came exactly a year to the day before his successor, whoever he or she house and the obamas will move out. >> so did they sell you on one of these things? >> i tell you what. this is a spiffy car. >> reporter: the president seems especially conscious of that

here was to browse for a new car. after all, he'll soon have to say good-bye to the one he's been using, which is a far cry, by the way, from any car, let alone the one he used to drive. >> do you remember the first car you had? what did you have? >> the first car i drove was my grandfather's granada, which was not a shining moment for detroit. it was not a great car. >> not a great date car either. >> it was not cool. i had to compensate in my coolness given the fact that i was picking girls up in the granada. >> reporter: although he was all smiles, the trips had a serious message. >> i could not be prouder of this industry and the road that we've traveled together. >> reporter: mr. obama has been struggling to communicate his successes heading into his last year in office. and the u.s. auto industry is one example. both gm and chrysler had record sales last year. a resurgence mr. obama says was

bailout during the first year of his administration. >> we cannot and we must not and we will not let our auto industry simply vanish. >> reporter: it wasn't a popular idea. critics thought the new president was overreaching, even cocky. but in hindsight, he says, that's just what the economic crisis demanded. >> i might have benefited from being young and a little brash probably should have been. there was probably some benefit to me thinking we can fix this. and we'll figure it out. >> reporter: by some measures mr. obama did figure it out. he's overseen shrinking unemployment, a growing job market. >> we are done. [ applause ] >> reporter: a reduction in the number of americans without health insurance.

both climate policy and relations with cuba. but his foes say those gains have been overshadowed by the rise of isis, the trouble in syria -- >> active shooter situation is still under way. >> reporter: -- and terrorism at home. and what stands out even to his supporters has been his inability to be the unifying force that he had promised. >> the one thing that gnaws on me is the degree of continued polarization. this has gotten worse over the last several years. and i think that in those early months my expectation was that we could pull the parties together a little more effectively. >> reporter: do you wish in hindsight that maybe campaigning on that notion of changing the tone in washington, do you wish you hadn't campaigned as hard on that promise? >> well, here's the thing. that's what the american people believe. and that's what i still believe. >> i believe in change because i

the american people. and that's why i stand here as confident as i have ever been that the state of our union is strong. >> reporter: his final state of the union seemed an attempt to remind america that despite the exasperating negativity the last seven years has not been as dismal or dysfunctional or as racially divided as his critics maintain. >> hands up, don't shoot! >> when i hear people say, for example, in the aftermath of ferguson and some of the other cases that race relations have deteriorated, they're terrible, i have to say, well, maybe it's just because i'm getting older, but they're not worse than they were after the rodney king incident in l.a. and they're certainly not worse than they were back in the '50s

if you could run for a third term, would you? >> no, i wouldn't. number one, michelle wouldn't let me. this is a great sacrifice and a great privilege, but it takes a toll on family life. this is a process in which the office should be continually renewed by new energy and new ideas and new insights. and although i think i am as good of a president as i have ever been right now, i also think there comes a point where you don't have fresh legs and that's when you start making mistakes or that's when you start thinking that you are what's important as opposed to the mission being more i'm very confident i'll be able to say that things are a lot better now than they were when i came into office. and you know, that's a pretty good eight years' worth of work. it enhances my body's natural moisture

swing of it a bit quicker. and when i know she's feeling like that, it makes me feel like we're both... when she enjoys it, we enjoy it even more. and i enjoy it. feel the difference with k-y ultragel. let's get these dayquil liquid gels and go. but these liquid gels are new. mucinex fast max. it's the same difference. this one is max strength and fights mucus. mucinex fast max. the only cold and flu liquid gel that's max-strength and fights mucus. let's end this. that's a lot of dishes& no problem. i'll use a lot of detergent. dish issues? get cascade platinum. one pac cleans tough food better than 6 pacs of the bargain brand combined.

a new exhibit at the natural history museum of london invites visitors to explore other worlds. the artist took raw data from nasa and the european space agency and transformed it into the art of the solar system. jonathan vigliotti took a spin around the show. >> reporter: explosions in the sky light years away are coming into focus never seen before, from the very active volcanoes on a jupiter moon to the rings

they are spectacular interstellar aspects of our solar system usually reserved for space missions, now on display for all to see at london's natural history museum. american photographer and writer michael benson gave us a preview of his other worlds exhibition before opening it to the public. >> i'm quite proud of this one because saturn is just a show stopper. >> it is. >> and it's right at the end of the show. so i hope people will leave on a high note. >> reporter: a show stopper not just for the unbelievable clarity and detail but also for the unusual process that gave benson an up close and personal glimpse of worlds often cloaked in mystery. each photo is actually a composite of a series of specialized images capturing different details. this series of photos are taken not by benson or any human for that matter but snapped by nasa spacecraft over the span of the agency's 60-year history.

putting together a jigsaw puzzle so typically you'll see an even more astonishing thing as you assemble it. >> reporter: it's a jigsaw puzzle that took benson years to complete. the end result is an exhibit of 77 stunning composites. a perfect fusion of art and >> reporter: dr. joe makowsky is history museum. >> in a technical sense this is very clearly an art exhibition for the natural history museum. we hope that people who appreciate art will come here for that. we hope people who come here for science will be pleasantly surprised by the art. >> reporter: and with all things art there is some interpretation. many of the original photos are received at nasa in black and white. benson uses historical and scientific data to determine the most accurate tones. >> sometimes i say oh, darn, i have to reprint this? >> reporter: benson's work is casting new light on space, much like ansel adams' photography revealed america's wild national

>> obviously i didn't haul my box camera on a tripod to saturn, and i wish i had that possibility. >> reporter: as a kid benson grew up wanting to go to space. instead he's bringing the solar system back to earth. >> i think it's part of growing up as a species to recognize where we are in the universe. that's part of what i'm doing, you know, i think, is trying to bring the message. or with the help, a little bit of help from nasa and the european space agency. >> reporter: jonathan vigliotti, london. 2016 is still young, but already some of the biggest names in rock music have passed away. anthony mason sat down with rock and roll hall of famer graham nash to talk about the loss of two contemporaries. >> reporter: january's been a cold month for music lovers. the eagles' glenn frey suddenly gone. just a week after david bowie.

their fellow musicians. >> yeah. because who's next? >> reporter: talking with graham nash about another topic this week, we kept coming back to the shock of it. >> there was something particularly jarring about both of them. i don't know what. >> because it was completely unexpected. >> yeah. >> i mean, glenn was what, 67? >> yeah. >> wow. bowie's 69. >> are you feeling the clock any more after this month? >> i've been feeling the clock a lot in this last six months. teach your children well >> reporter: nash has had a 50-year career in music. hey, cherry ann starting with the hollies. are you thinking and then with crosby stills & nash. and young. >> i mean with all due respect, anthony, we have talked many times and you know my next birthday, in less than two weeks i'll be 74 years old. and it's stunning to me that i

that i still have for communicating. it's amazing to me. and i'm just going to go right along with it until it, you know, comes to an end. look up here >> reporter: bowie's end, and just days after he released his latest album, "blackstar." but after a while glenn frey died just months after the eagles had wrapped up a two-year tour. >> it's really weird. i listen to cbs news a lot, you know, on the hour in my car. >> yep. >> and you hear, you know, co-founder of the eagles glenn frey died today and ba-daba-da-bada. and then i put myself in there, rock and roll hall of famer graham nash died today. and it will be gone and in five minutes it will all be over. it's kind of interesting. so what do you do with the time left?

as an artist and as a human being to have the best time you can. >> yeah. >> as we face our future. >> right. don't even try >> reporter: artists hope their music lives forever. but rock stars don't. we've been reminded of that this month, when an eagle left us and

steve hartman stopped at a roadside restaurant and brought us back a story as sweet as honey. >> reporter: what makes tim's place restaurant in albuquerque, new mexico so special is that it is indeed tim's place. >> hello. how are you doing today? welcome to my place. >> reporter: tim harris was the first restaurant owner in the country with down syndrome. for the last five years he has lived for his business. which is why his customers were shocked when tim announced recently that he was closing. >> my customers cried a lot. into my arms. >> going to miss you.

man to give up a job he loves more than anything? >> oh, yeah. >> reporter: a girl he loves more than anything. >> i cannot wait. >> reporter: that blur in the "i love tim" t-shirt is tiffany johnson. they met at a down syndrome convention. >> i was like oh, my god, he's like -- oh, my god. >> did you go up to him and say something? >> i was too scared to. >> too scared to? >> because i never met a guy like tim. >> reporter: tiffany says it was the weirdest feeling. >> i got hit by the love bug. >> reporter: eventually tim got bit by it too. >> will you be my girlfriend? >> you know i will. yes. >> reporter: he made her his steady and decided to move to denver to be closer to her. tim plans to open a new restaurant there. but it's still going to be hard leaving what he knows. in fact, he cries every time he thinks about it. >> it's just very sad. really sad.

he's deeply grieving about the idea of this transition. >> reporter: tim's father, keith. >> while at the same time being as excited as i've ever seen him with tiffany. >> i'm lucky to have someone that loves me. >> every time i feel sad my girlfriend makes me a lot happier. >> i'm trying not to start crying. >> when you look her in the eye what do you see? >> i see love. i see joy. and i see that i have a future. >> reporter: why on earth do we call them disabled? >> i just love him. >> reporter: when on the important things they can be so much more able than us. >> i love you. >> reporter: steve hartman, on the road in albuquerque, new mexico. >> that is the overnight news for this monday. for some of you the news continues. for others check back with us a little later for the "morning news" and "cbs this morning."
