>> no, john, we started the campaign 60 points behind secretary clinton. in the last couple weeks, a little bit, we have come in, in an enormous way. we are running against the most powerful political organization in the united states of america. i am very proud of the campaign that we have run. we have won 16 states right now. in almost all of the contests we win, the younger people, by that i mean not just kids, but you, know people, 45 years of age or under. i think the ideas we are talking about are what the american people and people in the democratic party want to hear. we are the future of the democratic party. so i am very proud of where we are and we look forward to fighting this out through california. >> one of the issues you talked about so much is income of inequality. and pr did analysis and found in places where income of inequality was high, hillary clinton was winning in those places you. were asked about this on meet the press. you said poor people don't vote. in states like ohio, florida, new york, michigan which you won. those who would be, earning less than $30,000 ended up voting more for hillary clinton. that doesn't seem to be the case. >> well for a start. one of the challenges we have as a nation is that we have one of the lowest voter turnouts in general of any major country on earth. 63% of the american people didn't vote. those numbers were worse for young people and for low income people. i believe that, what we are trying to do in this campaign, john, with some success, is bring people into the political process. and obviously we, have got to do better. but i would hope that -- if i am the nominee, that on election day you are going to see a very, very large voter turnout. and if that is the case, i think think we can change the dynamics of american politics, so it is not just big money interests, who help elect candidates through, throughout ray just campaign contributions, but what we have is a vibrant democracy where all people participate. >> senator sanders, thank you so much. >> thank you very much. >> watch the full interviews go to cbsnews.com. and click face the nation. we will be right back. you wanna see something intense?
