WISCONSIN — A new poll reveals Wisconsin voters remain largely undecided about who they want for governor in 2026, with former Lt. Gov. Mandela Barnes leading Democrats at 16% and U.S. Rep. Tom Tiffany topping Republicans at 30%.

The Badger Battleground Poll, conducted by Platform Communications from Sept. 28-30, surveyed 500 people by cell phone and landlines. The results show wide-open primaries in both parties, with significant numbers of undecided voters.

Barnes, who lost a close U.S. Senate race in 2022, leads the Democratic field as he still thinks about running in 2026. Current Lt. Gov. Sara Rodriguez follows at 8%, while Milwaukee County Executive David Crowley is tied with Attorney General Josh Kaul at 7%. Kaul has not announced whether he will seek the governor's office.
