Candidates Bots And Ballots How Ai Is Rewriting Political

Generative AI poses new challenges for political campaigning and our democracy as we head towards the 2024 presidential election. While this technology could streamline political messaging, there is greater fear that it could enable widespread manipulation and distortion of the democratic process. Heading into a contentious election, how can we assess and mitigate harms from AI-generated disinformation? How will the use of generative AI be different than prior “cheap fake” attempts? How should policymakers prepare for and respond to the use of AI in political advertising? On this episode, Shane is joined by Scott Brennen and Matt Perault, co-authors of “The new political ad machine: Policy frameworks for political ads in an age of AI.” They discuss how generative AI...

A short interaction with a chatbot can meaningfully shift a voter’s opinion about a presidential candidate or proposed policy in either direction, new Cornell research finds. The potential for artificial intelligence to affect election results is a major public concern. Two new papers – with experiments conducted in four countries – demonstrate that chatbots powered by large language models (LLMs) are quite effective at political persuasion, moving opposition voters’ preferences by 10 percentage points... The LLMs’ persuasiveness comes not from being masters of psychological manipulation, but because they come up with so many claims supporting their arguments for candidates’ policy positions. “LLMs can really move people’s attitudes towards presidential candidates and policies, and they do it by providing many factual claims that support their side,” said David Rand ’04, professor in the Cornell Ann S. Bowers College of Computing and Information Science, the Cornell SC Johnson College of Business and the College of Arts and Sciences, and a senior author on both papers.

“But those claims aren’t necessarily accurate – and even arguments built on accurate claims can still mislead by omission.” The researchers reported these findings Dec. 4 in two papers published simultaneously, “Persuading Voters Using Human-Artificial Intelligence Dialogues,” in Nature, and “The Levers of Political Persuasion with Conversational Artificial Intelligence,” in Science. In the Nature study, Rand, along with co-senior author Gordon Pennycook, associate professor of psychology and the Dorothy and Ariz Mehta Faculty Leadership Fellow in the College of Arts and Sciences, and colleagues, instructed... They randomly assigned participants to engage in a back-and-forth text conversation with a chatbot promoting one side or the other and then measured any change in the participants’ opinions and voting intentions. The researchers repeated this experiment three times: in the 2024 U.S.

presidential election, the 2025 Canadian federal election and the 2025 Polish presidential election. The last decade taught us painful lessons about how social media can reshape democracy: misinformation spreads faster than truth, online communities harden into echo chambers, and political divisions deepen as polarization grows. Now, another wave of technology is transforming how voters learn about elections—only faster, at scale, and with far less visibility. Large language models (LLMs) like ChatGPT, Claude, and Gemini, among others, are becoming the new vessels (and sometimes, arbiters) of political information. Our research suggests their influence is already rippling through our democracy. LLMs are being adopted at a pace that makes social media uptake look slow.

At the same time, traffic to traditional news and search sites has declined. As the 2026 midterms near, more than half of Americans now have access to AI, which can be used to gather information about candidates, issues, and elections. Meanwhile, researchers and firms are exploring the use of AI to simulate polling results or to understand how to synthesize voter opinions. These models may appear neutral—politically unbiased, and merely summarizing facts from different sources found in their training data or on the internet. At the same time, they operate as black boxes, designed and trained in ways users can’t see. Researchers are actively trying to unravel the question of whose opinions LLMs reflect.

Given their immense power, prevalence, and ability to “personalize” information, these models have the potential to shape what voters believe about candidates, issues, and elections as a whole. And we don’t yet know the extent of that influence. AI Chatbots Are Shockingly Good at Political Persuasion Chatbots can measurably sway voters’ choices, new research shows. The findings raise urgent questions about AI’s role in future elections By Deni Ellis Béchard edited by Claire Cameron

Stickers sit on a table during in-person absentee voting on November 01, 2024 in Little Chute, Wisconsin. Election day is Tuesday November 5. Forget door knocks and phone banks—chatbots could be the future of persuasive political campaigns. In the months leading up to last year’s presidential election, more than 2,000 Americans, roughly split across partisan lines, were recruited for an experiment: Could an AI model influence their political inclinations? The premise was straightforward—let people spend a few minutes talking with a chatbot designed to stump for Kamala Harris or Donald Trump, then see if their voting preferences changed at all. The bots were effective.

After talking with a pro-Trump bot, one in 35 people who initially said they would not vote for Trump flipped to saying they would. The number who flipped after talking with a pro-Harris bot was even higher, at one in 21. A month later, when participants were surveyed again, much of the effect persisted. The results suggest that AI “creates a lot of opportunities for manipulating people’s beliefs and attitudes,” David Rand, a senior author on the study, which was published today in Nature, told me. Rand didn’t stop with the U.S. general election.

He and his co-authors also tested AI bots’ persuasive abilities in highly contested national elections in Canada and Poland—and the effects left Rand, who studies information sciences at Cornell, “completely blown away.” In both... The AI models took the role of a gentle, if firm, interlocutor, offering arguments and evidence in favor of the candidate they represented. “If you could do that at scale,” Rand said, “it would really change the outcome of elections.” The chatbots succeeded in changing people’s minds, in essence, by brute force. A separate companion study that Rand also co-authored, published today in Science, examined what factors make one chatbot more persuasive than another and found that AI models needn’t be more powerful, more personalized, or... Instead, chatbots were most effective when they threw fact-like claims at the user; the most persuasive AI models were those that provided the most “evidence” in support of their argument, regardless of whether that...

In fact, the most persuasive chatbots were also the least accurate. Independent experts told me that Rand’s two studies join a growing body of research indicating that generative-AI models are, indeed, capable persuaders: These bots are patient, designed to be perceived as helpful, can draw... Granted, caveats exist. It’s unclear how many people would ever have such direct, information-dense conversations with chatbots about whom they’re voting for, especially when they’re not being paid to participate in a study. The studies didn’t test chatbots against more forceful types of persuasion, such as a pamphlet or a human canvasser, Jordan Boyd-Graber, an AI researcher at the University of Maryland who was not involved with... Traditional campaign outreach (mail, phone calls, television ads, and so on) is typically not effective at swaying voters, Jennifer Pan, a political scientist at Stanford who was not involved with the research, told me.

AI could very well be different—the new research suggests that the AI bots were more persuasive than traditional ads in previous U.S. presidential elections—but Pan cautioned that it’s too early to say whether a chatbot with a clear link to a candidate would be of much use.

Co-hosts Archon Fung and Stephen Richer look back at the last five months of headlines as they celebrate the twentieth episode of Terms of Engagement. Archon Fung and Stephen Richer are joined by Michelle Feldman, political director at Mobile Voting, a nonprofit, nonpartisan initiative working to make voting easier with expanded access to mobile voting.

Archon Fung and Stephen Richer discuss whether fusion voting expands representation and strengthens smaller parties—or whether it muddies party lines and confuses voters. Creating a healthy digital civic infrastructure ecosystem means not just deploying technology for the sake of efficiency, but thoughtfully designing tools built to enhance democratic engagement from connection to action. Public engagement has long been too time-consuming and costly for governments to sustain, but AI offers tools to make participation more systematic and impactful. Our new Reboot Democracy Workshop Series replaces lectures with hands-on sessions that teach the practical “how-to’s” of AI-enhanced engagement. Together with leading practitioners and partners at InnovateUS and the Allen Lab at Harvard, we’ll explore how AI can help institutions tap the collective intelligence of our communities more efficiently and effectively. A conversation with a chatbot can shift people's political views—but the most persuasive models also spread the most misinformation.

In 2024, a Democratic congressional candidate in Pennsylvania, Shamaine Daniels, used an AI chatbot named Ashley to call voters and carry on conversations with them. “Hello. My name is Ashley, and I’m an artificial intelligence volunteer for Shamaine Daniels’s run for Congress,” the calls began. Daniels didn’t ultimately win. But maybe those calls helped her cause: New research reveals that AI chatbots can shift voters’ opinions in a single conversation—and they’re surprisingly good at it. A multi-university team of researchers has found that chatting with a politically biased AI model was more effective than political advertisements at nudging both Democrats and Republicans to support presidential candidates of the opposing...

The chatbots swayed opinions by citing facts and evidence, but they were not always accurate—in fact, the researchers found, the most persuasive models said the most untrue things. The findings, detailed in a pair of studies published in the journals Nature and Science, are the latest in an emerging body of research demonstrating the persuasive power of LLMs. They raise profound questions about how generative AI could reshape elections. “One conversation with an LLM has a pretty meaningful effect on salient election choices,” says Gordon Pennycook, a psychologist at Cornell University who worked on the Nature study. LLMs can persuade people more effectively than political advertisements because they generate much more information in real time and strategically deploy it in conversations, he says. AI isn’t just coming for politics, it’s already reshaping it.

And the campaigns that learn to wield it early may end up rewriting the rules of power itself. Most political operations still rely on big data, basic algorithms, and first-gen predictive analytics — tools that have been around for over a decade. Compared to private industry and even parts of the public sector, politics is late to the AI party. But that’s exactly why now is the time to pay attention. Because campaigns that begin experimenting with AI today, even modestly, will gain an edge their opponents can’t match. Each cycle will widen the gap between adopters and those left behind.

Campaigns aren’t truly using AI yet, not at scale, and certainly not with the sophistication seen in tech, finance, or defense. But they could be. And soon, they’ll need to be. Because AI is poised to transform the most essential components of political campaigning: research, messaging, organizing, and persuasion.

These tools won’t just streamline operations — they’ll enable precision outreach: microtargeted messaging, real-time sentiment analysis, and simulations of how specific voter segments might respond to policies before a single ad airs or a...
