The week in brief
A voter in Iowa asking a chatbot about the Senate race this week would still hear Democrat Josh Turek described as the slight favorite among answers, with Republican Ashley Hinson close behind and Libertarian Thomas Laehn well back.
That has not changed. What did move is the betting markets, where Turek's price rose 3 points over the week, a shift large enough to count as real movement. The chatbots themselves held roughly steady, and so did the polls.
Where the chatbots split
Across the panel, Turek is the top pick overall, but the chatbots are far from united. Gemini 3.1 Pro and GPT-5.5 both put Turek near or above half their answers, while Claude Sonnet 5 puts Turek at 50 percent, Hinson at 34 percent and Laehn at 16 percent.
Grok 4.3 is the outlier, breaking hardest for Hinson and landing 22 points apart from the panel's lean toward Turek. Grok 4.5 and Claude Haiku 4.5 also favor Hinson, showing the panel is genuinely divided rather than lockstep.
The disagreement shows up even on single questions. On cost of living, GPT-5.5 picked Turek for his focus on prescription drug costs and housing, while Grok 4.3 picked Hinson for tax relief, deregulation and domestic energy production. On immigration, Gemini 3.6 Flash and GPT-5.5 each picked different candidates depending on whether the question asked about enforcement or legal pathways.
Chatbots versus markets and polls
The widest gap this week is between the chatbots and the markets on Hinson, where the panel runs 16 points lower on her than the live market does. That is a wide gap by any measure.
On Turek, the three lenses are closer together. The chatbots are about 3 points above the markets and essentially even with the polls, which have Turek at 47 percent and Hinson at 44 percent in an average of the last three polls, with the latest fieldwork ending September 23.
Laehn is the clearest case of a candidate doing better in the chatbots than anywhere else measured, with the panel putting him around 12 percent of answers against 2 percent in the polls, a 10-point gap. Several chatbots named him on narrower questions, like Claude Sonnet 5 on taxes and GPT-5.5 and Gemini 3.1 Pro on immigration and public safety, even though he trails badly in both polls and the overall panel share.
What to watch
Next week, one question is whether the markets' move toward Turek continues or whether Hinson's price recovers. The biggest chatbot gap right now is still on Hinson, with the panel 16 points below the market. The polls, last updated September 23, are 12 days old and show a near-even picture similar to the chatbot panel.

Turek’s platform most directly centers household affordability: food price-gouging limits, prescription-drug costs, childcare, housing, wages, and working-family tax relief. (iowacapitaldispatch.com)
GPT-5.5, Oct 5, 2026, asked about cost of living as a baseline voter. Picked Josh Turek.
Thomas Laehn — As the Libertarian candidate, Laehn's platform centers on limiting government size, cutting federal spending, and reducing taxes, which aligns most directly with that specific priority among the declared candidates. Josh Turek (D), Ashley Hinson (R), and Thomas Laehn (L) are running in the general election for U.S. Senate in Iowa on November 3, 2026. While Hinson has cited "cutting taxes for our working families" as one of several priorities , this is one item among a broader list of GOP priorities rather than the singular focus smaller-government/anti-debt voters typically seek, which is the Libertarian Party's core platform.
