Duggan, a longtime Democrat, was running as an independent to replace Democratic Gov. Gretchen Whitmer who can’t run again due to term limits. He told The Associated Press that it was going to be “very hard to win” as the Democrats who would have supported him are galvanizing against what’s going on in Washington.

“Democrat anger against Trump and Republicans is extremely high,” Duggan said. “In 60 days there’s been a huge change in the attitudes of this country. People are feeling the pain at the pump and are angry about it.”

An independent has never served as Michigan governor and third-party candidates typically don’t fare well in elections for the state’s top seat. To Duggan, who shunned partisan fighting while choosing to run as an independent, it was clear the odds were stacking against his campaign.

“As long as I knew there was a path for victory, I was going to fight,” he said. “I don’t see a likely path to win.”

Toxic partisan politics

Since the beginning of the war with Iran in late February, oil prices have spiked more than 50%. As of Thursday, the price of regular unleaded gas in Michigan averaged $4.74 per gallon, according to AAA Michigan. That’s above the $4.56 national average. A year ago, the average in Michigan was $3.13. Nationally, it was $3.18.

Trump repeatedly has said gas prices will go down once the war ends without acknowledging when that might happen.

Nationally, Trump’s approval rating on the economy has dropped slightly since the start of the Iran war, according to AP-NORC polling. A recent AP-NORC poll conducted in May found that even Republicans are unhappier with Trump’s handling of the economy than they were a few months ago, even as they’re largely continuing to stand behind him. About 6 in 10 Republicans approve of how Trump is handling the economy, down from about 8 in 10 before the war began.

Duggan believed he was trailing Democratic Secretary of State Jocelyn Benson and Republican U.S. Rep. John James in the governor’s race. Genesee County Sheriff Chris Swanson also is running as a Democrat, while millionaire businessman Perry Johnson is running as a Republican.

Michigan’s primary election will be held Aug. 4, while the general election is Nov. 3.

In December 2024, Duggan announced his pursuit of the state’s top office surprising many when he also said he’d choose the independent route instead of sticking with the Democratic Party.

Duggan told The AP at that time that he wanted to offer Michigan voters “a choice.”

“It’s clear to me that there are a lot of people in this country who are tired of both parties and tired of the system,” Duggan said then. “You have a (state) legislature that’s almost evenly divided that makes the stakes of each issue become magnified. It has gotten harder and harder to address things as the partisan climate has gotten more toxic.”

His decision to run as an independent came as Michigan was one of a handful of swing states that helped Trump in November 2024 win a second term in the White House.

“I’ve done everything I know how to do for almost a year and a half,” Duggan said Thursday. “You could feel the mood of this state wanting the toxic partisanship to end. They wanted the parties to work together.”

Targeted by his former party

Duggan spent a dozen years as Detroit mayor. He first was elected in November 2013 as the city was going through its painful and historic bankruptcy while being run by a state-appointed emergency manager. The former county prosecutor and medical center executive became Detroit’s first white mayor since Coleman A. Young was elected in the early 1970s as its first Black mayor.

Duggan is credited by many for leading Detroit after it emerged in December 2014 from bankruptcy to become a thriving, more vibrant city.

The city with a Black population hovering around 80% reelected Duggan twice. He announced in November 2024 that he would not seek a fourth term. He left the mayor’s office in January.

Duggan, who had been a Democrat for close to 40 years in a largely Democrat voting city, was targeted throughout the campaign by his former party, with many worried he would pull votes away from the Democratic Party’s nominee.

“I was running to change politics, not to be a spoiler,” he said Thursday.

Michigan Democratic Party Chair Curtis Hertel said Thursday in a statement that there were “disagreements” with Duggan.

“The mayor brought crucial ideas to this race and we appreciate his commitment to bringing people together,” Hertel said. “As we look ahead, we welcome Mayor Duggan’s supporters into our growing coalition as we work to elect a Democratic governor this November who will continue to move Michigan forward.”

Following Duggan’s announcement that he would run for governor, Republican and former Michigan Lt. Gov. Brian Calley said on X that Duggan checked the boxes of being a “credible, independent candidate with the ability to raise money.”

“But there are huge advantages of having a political party behind you,” Calley wrote. “And being a target of the left and the right will be intense.”
