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.

What decides the answer
The issue.
A voter who puts school funding or health care first is pointed to the Democrat by every chatbot; one who puts veterans and the military or federal taxes first, to the Republican. The chatbots part ways on the issues in between.
Four chatbots, four habits

The candidates AI lifts
1.1% → 18%
Bill Redpath (Libertarian, Ohio Senate) polls at 1.1% and gets 18% of the chatbots' picks. Most of those picks come from voters who put federal taxes or balanced foreign policy first.
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 1, 2026.
