Joel Brennan, a former top official in Gov. Tony Evers' administration, announced Thursday that he is running to succeed the two-term Democrat, joining a crowded primary field for the 2026 election.
Brennan, president of the Greater Milwaukee Committee, told The Associated Press that he would be a governor who both fights President Donald Trump's "chaos and dysfunction" and works across the aisle with Republicans in the state.
"You don't grow up in a family of 11 kids without learning how to fight," Brennan, the 10th of those 11 children, said in an interview. "But there's a difference between just fighting and getting something done."
Brennan said he wants to build relationships with both Democrats and Republicans to "roll up our sleeves and work together."
Other Democrats in the race include Lt. Gov. Sara Rodriguez; former Lt. Gov. Mandela Barnes; state Sen. Kelda Roys; state Rep. Francesca Hong; Milwaukee County Executive David Crowley, the highest elected official in the Democratic stronghold; and former state economic development director Missy Hughes.
Republican U.S. Rep. Tom Tiffany, a staunch Trump supporter, is the highest-profile GOP candidate. He faces a challenge from Washington County Executive Josh Schoemann.
An August primary will narrow the field ahead of the November general election.
Wisconsin is a politically divided state that went for Trump in 2016 and 2024 and former President Joe Biden in 2020. All three elections were decided by less than a percentage point.
Brennan, 55, said he can differentiate himself from his rivals with his 25 years of experience in the private sector and also as Evers' top aide for the first three years of his administration. He said he will tap his network of connections around the state to raise money and build a team that can win.
"It seems as if there's an opportunity that I may bring something to this field that others don't," Brennan said. "None of us can say that we have been governor, and each one of us will have to prove that we have the temperament and have the ability to do things on day 1."
Brennan was secretary of the state Department of Administration from 2019 to 2022. Since then he has been president of the Greater Milwaukee Committee, a group of about 200 leaders from business, financial institutions, law firms, nonprofits and others working to improve the economy and civic life of southeastern Wisconsin.
Previously he spent 11 years as executive director of Milwaukee's Discovery World, the state's largest science museum.
