welcome to the "cbs overnight news," i'm elaine quijano. with 84 days to go before election day, a new cbs news battleground tracker poll shows hillary clinton picking up steam against donald trump. clinton extended her lead in the swing state of florida. traditionally red state of georgia and dominating in new hampshire. john dickerson broke down the numbers on "face the nation." >> we have new battleground tracker numbers from three key states. starting with florida. hillary clinton lead donald trump with 5 points. georgia traditionally red state.

hillary clinton is down just four points. you would expect her to be down by more. donald trump its at 45. clinton at 41. and, new hampshire seems to be moving toward the blue column. hillary clinton lead donald trump, 45 to 36. there are only 85 days left until the election. so we turn to cbs news director of elections, anthony salvanto. give us your feeling about the overall picture of the election. >> when you look across the states. hillary clinton has a big enough lead in enough battleground states if she can hold it into fall, an if, she is in position to get elected to win. you know, what you see in battleground after battleground now. new hampshire is a perfect example. we add that to virginia we saw last week. do the polls and expect them to be close. always close. she has this big edge. if she hold it into the fall we may not call them battleground

for donald trump what this sets up for him. he doesn't have to just flip a close state here and there. in order to win. he now has to, actually actively go out and reverse, big lead in a lot of states. in order to be in position for him to win come fall. >> so a steeper climb for him in these traditional states. or if they fall off contention altogether that means his path to victory is really narrow. >> really narrow. give you an example out of new hampshire of how tough this looks from here. okay, so we asked people who aren't voting for donald trump, would you consider voting for him. with women who he is down 20 points any way. women who are not voting for him. number who say yes, they would consider it is 0. the number who say maybe is 9%. so if you are at 0 in the number of people who will kid you, going forward, that just emphasizes what a tough hill it is. >> so, what's his big challenge,

see it president? >> well he has a couple. one is, he is behind schedule if you will. in rallying his own base. his own partisans. there is republicans who have fallen away. they haven't all shifted en masse to hillary clinton, more undecided. unsure. but he its at, in the mid 70s, about 70-odd percent among americans. compare that to hillary clinton who is up in new hampshire at 93% of democrats. so in a very partisan environment, anyway, you have to get in the 90s with your base. so that just emphasizes the challenge. the question was donald trump and heartburn in republican ranks. your poll numbers suggest that is showingin people in terms of not sticking with him. >> yes, so different from the primaries. in the primaries the voters said they didn't care what republican leaders said and did about donald trump. here you have a much larger electorate that tells you in the polls that they do care some what. >> what is his other challenge? >> he's got when you look at the number of people who are willing to swing, who are going back and forth, it is small, very small. those undecideds have shifted to hillary clinton a small number.

in this race. is 1%. now, that's not to say hillary clinton isn't without some issues of her own. in fact if i told you a couple months ago she would be trailing donald trump in some of the states. on ability to fix the economy. on, honest and trust worthy. you might say she would be trailing. but in fact, it's these honest and,se has been facing showing up in the polls. that in particular weighing him down. >> so, while hillary clinton has lots of weakness, voters are picking temperament as the thing that for them right now, and it's hurting donald trump, that's the thing that is giegd their vote the most? >> exactl. you have seven in ten folks in florida for example, who feel like he does not have the judgment and temperament to be president.

anchor on him. hillary clinton its beating him there as she has been on the commander-in-chief test. so it's -- that's where the campaign has gone. when you see metrics like fixing the economy. you see in some sense, donald trump, the campaign that might have been or that might still be if he were to shift the focus to emphasize on the issues. as long as on temperament and judgment, that is an anchor for him. >> this week, donald trump said some exciting things. then said i was kidding. his -- his more incendiary comments? >> we asked about that. most of them feel it is irresponsible. only a minority feel like he is joking. among his supporters they say they think he is telling it like it is. that's 20-odd-percent. when you see a majority saying they feel like that is, those are irresponsible comments. not joking that goes to judgment and temperament metric that's become the emphasis. anthony salvonto.

joined now by republican senator susan collins who joins us from portland, maine. senator, last week you wrote in "the washington post" you could not the support donald trump. you said you realized that donald trump was never going to change. what tipped it for you? >> the tipping point for me was when he attacked the parents of it was inexplicable to me that anyone, much less a presidential candidate, would not honor the sacrifice and empathize with the family who lost a son in war. instead, he attacked them and attacked their religion. it was still a difficult decision for me because i'm a lifelong republican. and i wanted to and expected to be able to support our party's nominee.

people who are vulnerable and unable to fight back really troubled me. >> so, what you have talked about is, what some of his supporters would say kind of his blunt way of behaving. what is going to be responsible for allowing him to shake up washington. he is not a lifelong politician. maybe he is a little rough. that comes with some good side. why are they wrong in making that case? >> when you look at the hope, and abroad, we need a president who has the judgment, the temperament, the knowledge and the self-control to lead our country and to be the symbol of our country. >> to watch more go to cbsnews.com and click on "face the nation." we'll be right back. workout clothes are not just for working out anymore. designers are turning casual
