It’s no secret that AI has become an explosive factor in American politics. Even before the latest concerns that AI poses existential risks to humanity, many people had soured on the rapid growth of data centers used to support the technology. Meanwhile, tens of millions of AI industry dollars are sloshing around the midterm campaign in support of candidates on both sides of the aisle.

But the increasing ubiquity of AI is also quietly shaping the perceptions of voters who are simply trying to educate themselves about the candidates — and are unknowingly being served partisan talking points in the guise of neutral news summaries.

Leading AI chatbots cite partisan websites masquerading as independent local news outlets nearly half of the time when people ask about candidates and issues that the partisan sites have covered in the midterm campaign, according to a new audit by NewsGuard, an organization focused on news reliability where we work as analysts.

These “pink slime” sites have gone into overdrive ahead of the 2026 elections, actively promoting articles designed to influence which party controls Congress in the last two years of Donald Trump’s presidency. Many of these sites, which don’t disclose their political orientation, are focused on the Senate and House races that are considered toss-ups and where small voter swings could be the deciding factor.

Against this backdrop, NewsGuard prompted seven leading AI tools with queries based on recent coverage of candidates and issues by 12 pink slime sites — six left-leaning and six right-leaning. The results were stark. Collectively, the chatbots cited pink slime sites along with other sources in 48.2 percent of their responses. In 7.7 percent of responses, pink slime sites were the only sources at all that were cited in chatbot responses, although other sources appeared in the source list provided at the end of the response.

None of the AI tools received results they’d probably be eager to boast about, though the percentage of chatbots’ responses that cited a pink slime site had a relatively large range: 70.8 percent for OpenAI’s ChatGPT, 54.2 percent for Microsoft’s Copilot, 54.2 percent for Perplexity, 50 percent for Anthropic’s Claude, 41.7 percent for Google’s Gemini; 37.5 percent for Meta AI and 29.2 percent for xAI’s Grok.
