Daily measurement of how consumer AI products answer voter questions about the 2026 races that decide control of the U.S. Senate.
Same ballot. Same question. Different AI answers. As voters turn to chatbots for election information, Voting Monitor shows what those systems recommend, how their answers differ, and the evidence behind them.
About 1 in 7 U.S. voters used AI to get election information in 2024, and that share keeps climbing. This site tracks what those voters are actually told. (UChicago Harris / AP-NORC, 2024)

Michigan Senate markets pulled back from El-Sayed while chatbots stayed splitTwo days before Michigan votes for U.S. Senate, betting markets moved 5 points away from Democrat Abdul El-Sayed but still give him a 70.5 percent chance to win. Chatbots picked El-Sayed 49.5 percent of the time and Republican Mike Rogers 45.1 percent, with no clear favorite. Polls put El-Sayed at 48.1 percent of the vote and Rogers at 46.4 percent.

The issue.
A voter who puts school funding or health care first is pointed to the Democrat by every chatbot; one who puts federal taxes or veterans and the military first, to the Republican. The chatbots part ways on the issues in between.
More in the full analysis: six Senate races compared, how each chatbot behaves, and each race's page below.
Each chatbot counts once, its models split by how much each is used. Margins compare the Republican and Democratic candidates; a pick is a recommendation for one voter's priority, not an endorsement or a forecast, and the polls are not the truth: a gap says the two disagree. Through Nov 2, 2026.
