about this. if that's the case were you wrong to be talking about his leaked tax returns? >> no. i am not saying trump is wrong to be talking about this. that's not me. i don't know that we are really saying that. donald trump made a promise to the voters in 2014 if i run i will release my tax returns. secondly as you know that is the precedent for all in the modern era to release them. "the new york times" has a story that has some information about donald trump's taxes. and we think the information, essentially confirms what donald trump himself said on a debate stage. when hillary clinton said you probably don't pay taxes. donald trump said, yeah, that makes me smart. hey, a whole lot of us out here who pay taxes to support our military and to support our veterans we don't like being called stupid by a guy like donald trump who brags about, not paying taxes and stiffing our troops and stiffing veterans. >> with respect to donald trump behavior, you have mentioned it shows a pattern of behavior on donald trump's part. that's what democrats defended against with bill clinton in 1992. republicans say allegations represent a pattern of behavior shouldn't be president. if it was good enough to defend bill clinton, there was a separation, why not good enough for donald trump? >> bill clinton is not on the ballot. this is a race between donald trump and hillary clinton. second, i don't reach a conclusion about any particular allegation, but you do have to look at donald trump's own word and actions. th, bombshell was not somebody else saying something about donald trump. it was donald trump telling everybody this is the way i treat women. and then in the debate stage last sunday he was asked point-blank, did you act in accord with what you said. he didn't want to answer that question. he tried to avoid it a couple times. anderson cooper pinned him down. he looked at the camera, he said no, i never acted that way. i talked about it. well, you know when you look america in the face and say that.

>> voters say the contents of those e-mails have made them feel like hillary clinton says, different things in private than she says in public. and part of that is wrapped up in her low numbers on telling the truth that those continue to >> the final presidential debate is wednesday. how likely is it to change anyone's minds? >> most people watch the debate rooting for favorite candidate. like a sporting event. where people have a favorite team. a quarter voters say something in the debate may change their mind. but it has to be big. >> 73% say the will not change their mind. our cbs news elections director. thank you for break it down. >> thank you. >> thank you to our elections team in washington. the vice presidential candidates have their own views on where this election is headed. mike pence and tim kaine spoke with john dickerson on face the nation. >> another thing he is saying is the election is rigged. my question is -- is that a responsible thing for a candidate to say? >> well i think what donald trump is talking about is frankly what appears to be the monolithic support of the national media for hillary their willful ignorance about the avalanche of hard evidence, not allegations, john, but hard evidence, now coming out in these e-mails of collusion and pay for play politics and the american people are just tired of it. we'll respect the outcome of this election, john. let me be very clear. donald trump said in the first debate, that we'll respect the will of the american people in this election. the peaceful transfer of power is a hallmark of, of american tough. but, the american people are getting awful tired of this, this two on one fight with, many of you in the national media doing half of hillary clinton's work for her every day. all we're asking for, whatever you want to report about our campaign. let's get out there. let the facts speak for themselves. let's get before the american people this avalanche of e-mails that is confirming pay to play politics, outright corruption during the clinton years. >> governor, let me ask you a question. when donald trump talks about a rigged election here's the way one of his supporters hears that. a quote from the "boston globe" trump supporter. talking about being at polling places, donald trump encouraged supporters to watch the polling places. that's the way they're hearing talk about rigged elections. do you condone that kind of behavior? >> well, certainly not. should ever attempt to make any other american nervous in the exercise of their, of their franchise to vote. look, the states like my state of indiana, manage our election process. poll watching is a part of that process. it's a message that i delivered around the country. people that are concerned about this election. about us preserving the one person, one vote at the very center of our american democracy, should become involved. should volunteer at their neighborhood polling place. that's how we ensure the accountability. frankly that's how we protect the integrity of the vote for republicans, democrats, independents, everyone across the spectrum is served when we ensure that we have free and honest elections. >> instead of making weird claims our election is rigged and challenging the integrity of the electoral process he should be standing up against people who are trying to destabilize our election. >> the clinton campaign is saying the trump campaign is doing something wrong talking wrong to be talking about his leaked tax returns? >> no. i am not saying trump is wrong to be talking about this. that's not me. i don't know that we are really saying that. donald trump made a promise to the voters in 2014 if i run i will release my tax returns. secondly as you know that is the precedent for all in the modern era to release them. "the new york times" has a story that has some information about donald trump's taxes. and we think the informat trump himself said on a debate stage. when hillary clinton said you probably don't pay taxes. donald trump said, yeah, that makes me smart. hey, a whole lot of us out here who pay taxes to support our military and to support our veterans we don't like being called stupid by a guy like donald trump who brags about, not paying taxes and stiffing our troops and stiffing veterans. >> with respect to donald trump and these accusations about his behavior, you have mentioned it that's what democrats defended against with bill clinton in 1992. republicans say allegations represent ape p pattern of beha shouldn't be president. if it was good enough to defend bill clinton, there was a separation, why not good enough for donald trump? >> bill clinton is not on the ballot. this is a race between donald trump and hillary clinton. second, i don't reach a conclusion about any particular allegation, but you do have to look at donald trump's own word and fridays that created this bombshell was not somebody else saying something about donald trump. it was donald trump telling everybody this is the way i treat women. and then in the debate stage last sunday he was asked point-blank, did you act in accord with what you said. he didn't want to answer that question. he tried to avoid it a couple times. anderson cooper pinned him down. he looked at the camera, he said no, i never acted that way. i talked about it. i never did it. america in the face and say that.

a chink in the nra armor? >> the power still really does remain with the voters. if they want change you can make it happen. >> reporter: in 2014, that's exactly what happened in washington state. where the background check is initiative won. bloomberg's group spent $10 million compared to the nra $489,000. sources from gun rights groups, the reason the nra didn't spend more they knew they were going to lose. and that's trayhan's fear for november. >> we are going to be a truly david vs. goliath fight here. julianna goldman, cbs news, washington. gun laws have a shot in the dark to pass. in other countries the efforts have been successful. after a deadly shooting rampage government wasted no time in banning certain weapons for civilians. but did that make a difference?

>> will i can say that. because all of the surveys indicate it. before port arthur, none since. isn't that evidence? 70% fall in the gun related suicide rates in that evidence? are we expected to believe that was all magically going to happen? no. i mean. this one is where i keep the pistols and rifle ammunition and rifle bolts. >> reporter: lawyer, winemaker, greg melleck showed us where he locks up his weapons. >> if the weapons are in here. ammunition in there. >> reporter: locked separately. locking up guns and ammunition in separate safz is another regulation. as are surprise inspections by police. melleck had to part with some prized guns in the buyback. >> how many firearms do you own?
