>> i don't buy that scenario. i've heard that. and i wouldn't buy that scenario because if you look back in history how things have played out, i don't think they thought ross perot would elect bill clinton. now that we see some polls with bobby kennedy jr., would be helping -- would be helping joe biden because it takes votes from donald trump. i've never been a spoiler in anything. i've never tried to. i compete the best i possibly can. i compete to win. okay? and i am going to work, right now, to try to win the middle back. they've got to decide, i want things different. i want to make a change. >> norah: how do they do that? >> getting involved. saying, listen, you would be surprised at how things can happen when there is a movement saying, you are not giving me an option. >> norah: what is causing the election of increasingly more partisan people? less moderates. why isn't the system electing moderates? >> well, the system is closed. it's a closed system. the business model is basically, you control all from birth to the finality of it, so if it is starting at the grassroots level back in your home, could be a home district. senators are statewide, congresspeople are districtwide. it is basically designed that we are going to have this ideology no matter what, whether it is you, me, or whoever, but someone will come from we consider more extreme has a better chance of winning than someone that is more moderate or conservative. >> norah: senator romney told me, "i really think that independent candidates are likely to elect donald trump, and i think him being elected again would be devastating for our country and its character." do you agree with that? >> i agree with the second part, not the first. [laughs] he and i have talked about this many times. i think the best you can say that is going to help or hinder one or the other. >> norah: so you and mitt romney have talked about whether an independent candidate would help elect donald trump? >> we can't help but talk about it because that is all you hear about in the press. we have agreed to disagree. >> norah: are you concerned, then, if next year's presidential election is donald trump versus joe biden? >> very concerned. sure. >> norah: why? >> it would be detrimental for a person who i tried to work with as president -- >> norah: donald trump. >> right, and i couldn't get there with donald trump. but to, basically, this visceral hatred and degradation of human beings and talking about people that make up america, you know, you can't -- you can't be a person who believes the only fair election is the one you win. you can't be a person who believes the only laws pertain to everybody but me. there is no privilege like that in america. it wasn't designed that way. >> norah: well, we are going to have much more of our conversation tomorrow on "cbs mornings." now to tonight's "eye on america," we go inside a high school classroom as students grapple with how to understand the war between israel and hamas, and with so many kids getting their news from social media, cbs's nicole sganga reports on how teachers are tackling the conflict. >> and we are going to talk about some of the conflict. >> reporter: for students in stewart parker's ap human geography class, today's lesson is also today's news. >> gaza, israel, west bank... >> reporter: that has these high school freshman diving into the history of one of the world's most enduring conflicts. >> in israel, the cultural makeup is mostly jewish and muslim. >> reporter: and separating fact from fiction. >> how many of you have seen images of the conflict while you are looking at your social media feed? >> reporter: at winter park ninth grade center, just outside of orlando, parker knows this subject doesn't stay within his classroom walls. students don't get the complete picture by scrolling through instagram reels or tiktok. >> no, not at all. >> reporter: a recent survey found more than half of generation z teenagers polled get their daily news from social media platforms. images of the war filling their screens. >> especially in, like, the gaza strip, i saw, like, images of videos of, like, ambulances rushing kids younger than me out. >> reporter: leaving students like riley derrick and grace caron scrolling through an avalanche of information. some of it inaccurate. so you are noticing mis- and disinformation on your own social media feeds? >> for sure. >> reporter: how do you avoid it? >> sometimes you can't. >> reporter: a new study by the anti-defamation league reveals 70% of participants reported seeing misinformation or hate related to the conflict while on social media. >> this is the world we are taking in, and we can make impacts and try to improve it. >> a lot of people don't agree on the same religion, a lot of the time. >> reporter: parker says his students give him hope. >> since they are constantly on their social media, they see problems, but they want to fix them. >> that is more likely to cause pacifism and peace among groups of people. >> reporter: the changemakers of tomorrow. for "eye on america," nicole sganga, winter park, florida. >> norah: now to combating climate change, the white house unveils what it calls the most ambitious climate agenda in history. that's next. ♪ ♪ ♪ ♪ bitious climate agenda in history. that's next. ♪ ♪ when i first learned about my dupuytren's contracture, my physician referred me to a hand specialist. and i'm glad he did, because when i took the tabletop test, i couldn't lay my hand flat anymore. the first hand specialist i saw only offered surgery. so, i went to a second hand specialist who also offered nonsurgical options — which felt more right for me. so, what i'd say to other people with dupuytren's contracture is this: don't wait — find a hand specialist trained in nonsurgical options, today. i found mine at findahandspecialist.com. salonpas, makers of powerful pain relief patches for 89 years... believes in continuous improvement... like rounded corners that resist peeling, with an array of active ingredients... and sizes to relieve your pain. salonpas. it's good medicine. kayaking is my thing. running is awesome. but her moderate to severe eczema would make her skin so uncomfortable. now i'm staying ahead of it. dupixent helps heal your skin from within. so, they can have clearer skin and less itch. serious allergic reactions can occur that can be severe. tell your doctor about new or worsening eye problems such as eye pain or vision changes including blurred vision, joint aches and pain, or a parasitic infection. don't change or stop asthma medicines without talking to your doctor. ask your doctor about dupixent.
