how does it s sanders and clinton? scott: well, clinton very wisely her campaign went after them way early in this game. delegates it is tough math to understand. super delegate are not tied to a state result. they can vote however they want. clinton camp went after them a long time ago, got them to say yes, i am on your side. so she holds a huge margin, something like 15 to 1 at the super delegate count. they can change their mind. they are not bound to the endorsement they have given. anything can happen but if you look at the numbers she is ahead in that. leon: but anything can happen. that is what we have seen happen this campaign season. thank you, scott. check back with you later on. take care. alison: a couple of other notes here. on the republican side birthday. no excuse for rest. turned 63 but still held a rally in south carolina. you might think as the home to the president of the united states the white house would have had one of these for years. but this sign expressly prohibiting guns and dangerous weapons at

clinton in the pre-primary polls. when we asked democratic voters today most important quality, honest and trustworthy was number one. nancy cordes is covering the race for us. nancy. >> reporter: scott, hillary clinton and her husband launch aid series of attacks this week aimed at cutting into the sanders advantage on that honesty question. it's a risky strategy that can cut both ways. and there's no sign yet that it paid off. how are you feeling today? >> i'm feeling great. visit to a polling place in concord today-- >> feel the bern! feel the bern! >> reporter: and was mobbed by supporters anticipating a win. >> and it looks like there is going to be a large voter turnout. >> reporter: clinton made four stops, starting at dawn in manchester. ( cheers ) sounding upbeat, but realistic. how are you feeling about a comeback, secretary clinton? >> you know what, i'm just here to thank all of the people who have worked so hard for me. i've got a lot of longtime friends who have been working day and night for me. >> reporter: the clinton camp has tried to write off the sanders lead as nothing more than loving thy neighbor. after all, his home state of vermont is known here as "new hamps

is still looking into clinton's use of a private server, but, scott, the clinton campaign views this as a rare positive development in a year-long controversy. >> pelley: nancy cordes with the clinton campaign. nancy, thank you. today in the water emergency in flint, michigan, the e.p.a. said that lead levels are dropping and home filters appear to be working. but that isn't true everywhere as our adriana diaz discovered. >> we have this information sheet from e.p.a. >> reporter: e.p.a. agents have fanned out in flint, targeting homes where lead levels remain sphub -- stubbornly high. joe ragnone's tap water has the city's second highest amount of lead on record. it's classified as toxic waste. >> does it look like that water >> that looks like regular water? >> right. only to find out you got over 5,000... >> reporter: parts per billion. >> parts per billion. this is the reason why we never really even considered our water being bad. >> reporter: old and corroded led pipes in some homes are still releasing lead into the drinking water. since january 1st, 364 homes of the more than 5

conditions. >> raul, i'll get you in on that because john who is with us, his column was hillary clinton rips scott walker to make the bigger point. that's the point john was making there, you can have a dual track if you're bernie sanders and that may be his playbook if you're hillary clinton. >> she also landed a solid punch when she mentioned the fact based on bernie sanders' projections for his health plan, he needs a buy-in from governors. she mentioned scott walker as the kind of governor who would never go along with this point. undermining one of sanders' most popular points. one thing that is clear from the debate, if you're watching it, you know we're not in new hampshire anymore. this whole debate was filled with appeals to latino voter whose are about one third of the population in nevada, 17% of the electorate. also to african-american voters who are 28% of the population in south carolina. hillary clinton went out of her way, i thought, to mention deiondra hamilton, killed by milwaukee police. you see this references. they're eyeing these states and trying to make this push that they

clinton. nancy cordes is covering. nancy. >> reporter: scott, all you need to do is look at clinton's to understand why she lost big to sanders. eight years ago, in 2008, clinton's come-from-behind victory was due in large part to her success with women. she won among women by 12 point. but tonight, she lost women to bernie sanders by seven point, and that was driven mainly by younger women, under the age of 45, who went for sanders by a pretty stunning margin, scott, 69% to 29%. younger voters overwhelmingly went for sanders, and the clinton campaign knows they've got a lot of work to do to inspire younger voters and younger women in particular. the clinton camp anticipated this loss, and about a half an hour ago, they put out a memo from the campaign manager. he says the campaign is going to do better as it heads south, states with larger african american communities, hispanic communities. clinton leads big among minorities, and he argues, "that type of support was not created it has been forged over more than 40 years of fighting for and alo

wrong. >> reporter: at the debate, clinton was asked if she would release transcripts of her wall street speeches, and s said she'd look into it. i asked her today, scott, what there is to look into. that it's going to have to wait until after next tuesday's primary. >> pelley: nancy cordes with the key interview tonight. nancy, thank you. hillary clinton and bernie sanders will be john dickerson's guests on "face the nation" this sunday. donald trump is leading republicans in new hampshire, orloor tro in hth tn wdainit f t ton t.hidf tumoeesri t wndasta t aitn ir caoinheka tneaiiooohe r tkul cdohgn t me y ng crn aee.more 4,0 intz thihn msgnet hat totciesffse>>secseribyos>>daeneftr cry. u d ohe and peve aedyerehugaitovinea qephrien walng!ohheenll igfyut>>ulploove csf. pla,ashinrm is ssaiden wheaiveom oy.20ee d>>len hud hpeno oth le roy y bewesis comhaia, onotete h ofheebht alania tou aha aorng., though so far they allowed across. rebel groups have told us they also control of the main ng wtupa tiehel t hel b theb a trapping civilians. russia began launchingtrik syria in ptember, and iped llkif bou f e. mwi nonidin.ryantoout hich to syitasiengboreuieene

clinton could survive a loss here in iowa, but it wouldn't be much fun. sanders is leaving in his neighboring state of new points in the polls, and if he win, scott, clinton won't have chance to redeem herself until south carolina at the end of the month. >> pelley: nancy, thank you. it's worth remembering that only 30 delegates are at stake the tonight. it takes many hundreds to win either party's nomination. john dickerson is our cbs news political director and anchor of "face the nation." he's in iowa talking to iowans. john, iowa's conservatives are about as conservative as they come. tailor-made for cruz. what if he comes in second? >> it would be a blow. his campaign is always predicated on starting and doing well in iowa. that is because it's tailor-made for him there. there are so many evangelical voters here and conservative voters. his entire campaign is built around this idea that he can build a conservative revolution. if he can't do that here, it calls the whole thing enter question. but he has about $20 million cash on hand, and there are future contests in south carolina and then a number of southern states on first of march that would do w
