Duggan ends independent campaign, reshaping Michigan's gubernatorial field

Former Detroit Mayor Mike Duggan has ended his independent bid for governor of Michigan, clearing a path for the remaining candidates in a race that already featured a Flint political leader.

Duggan announced his withdrawal in May 2026, less than six months before the November general election. The former mayor cited fundraising challenges as the reason for his exit.

"The numbers just aren't there," Duggan said, according to reporting from Daily Detroit.

Duggan told his campaign team that national fundraising networks for independent candidates remain too immature to support a competitive statewide bid in 2026. His campaign website noted that governor races are now funded "overwhelmingly from well-established networks of national party money."

What it means for Flint voters

The withdrawal reshapes the Democratic primary field, where Chris Swanson, the Genesee County Sheriff, is one of three candidates seeking the nomination.

Swanson, who serves the Flint area, has been building his campaign around law enforcement experience and public safety. Campaign finance filings through December 31, 2025, showed Swanson had raised $1,448,651 and spent $1,178,225, leaving $270,425 in cash on hand, according to the Michigan Secretary of State.

The Democratic primary field includes:

  • Jocelyn Benson, Michigan Secretary of State, who is term-limited from running for re-election to her current post
  • Chris Swanson, Genesee County Sheriff
  • Kim Thomas, an auditor whose ballot signatures are facing scrutiny

Garlin Gilchrist, the lieutenant governor, had been a Democratic candidate for governor but withdrew from the race in January 2026 to run for Secretary of State instead.

Republican field remains crowded

On the Republican side, the field includes five candidates:

  • John James, U.S. Representative from Michigan's 10th congressional district
  • Perry Johnson, businessman and 2022 gubernatorial candidate
  • Mike Cox, former Michigan Attorney General
  • Aric Nesbitt, Michigan Senate Minority Leader
  • Ralph Rebandt, pastor and 2022 gubernatorial candidate, whose ballot signatures are also facing potential questions

James told reporters over the Memorial Day weekend that he had already reached out to Duggan following the withdrawal.

"I've already reached out so we are really staying focused on what people around the state are telling me they want," James said at the St. Clair Shores Memorial Day Parade, according to The Macomb Daily.

Polling showed Duggan as a factor

A poll conducted by the Lansing-based Glengariff Group in April 2026 showed Duggan drawing significant support in the three-way race. The survey found Jocelyn Benson at 34.2%, John James at 29.2%, and Mike Duggan at 23%.

Duggan's exit is widely viewed as benefiting Benson, who already held a lead in the polling. Multiple aggregate polls through May 2026 showed Benson leading all potential Republican challengers by wide margins.

Election timeline

The Michigan primary election is scheduled for August 4, 2026. The general election will take place on November 3, 2026.

Incumbent Governor Gretchen Whitmer is ineligible to seek re-election, having served two terms. The race to succeed her has drawn significant attention from both parties and national observers, with Michigan identified as one of five Democratic-held governorships up for election in 2026.
