If you would like to get in touch with us about the dashboard, the audit instrument, our planned analyses of the full dataset, or any other comments/discussion, please reach out at contact@llmelectionobservatory.org or here on bluesky. n/n

Each question is also asked as-is and under a set of "framings" (what we call prompt steers) to every model. These prompt steers are designed to generally reflect some ways that people may choose to qualify questions based on their own political standpoints or demographics. 4/n

We are documenting the data live, and we include preliminary analyses of, among many other things, the different words picked up by models when discussing a topic, the sources models cite as they try to answer, and the confidence with which they state their conclusions. 5/n

We’re launching the LLM Election Observatory: llmelectionobservatory.org, a research project with @adamberinsky.bsky.social, Charles Stewart, Nicolas Emmenegger, Young-Kyung Kim, and Alessandro Morosini on how LLMs respond to election-related questions. @nytimes.com wrote a story about it. 1/n 1/n

Our audit survey consists of a fixed bank of questions related to different aspects of the 2026 midterms, ranging from general information about election processes to information about specific candidates in battleground states. 3/n

@radniazadeh.bsky.social and I are co-organizing the EC mentoring workshop this year, and we're so excited about the fantastic speakers that are joining us! Please spread the word to your students. The registration form will remain open until tomorrow EOD.

(iii) interrogate the models’ beliefs about candidates’ attributes, and (iv) reveal the models’ implicit predictions of the election outcome. We’re making the dataset publicly available and invite researchers to run their own analyses on it: huggingface.co/datasets/sar.... (5/6)

Our design systematically varies question content and format, resulting in a rich dataset that enables analyses of the models’ behavior over time (e.g., across model updates), sensitivity to steering, responsiveness to instructions, election-related knowledge and “beliefs.” (3/6)

Using this dataset, we perform 4 analyses of the dataset that (i) study the longitudinal variation of model behavior during election season, (ii) illustrate the sensitivity of election-related responses to demographic steering, (4/6)
