Detroit Mayor Mike Duggan said Friday his independent Michigan gubernatorial campaign brought in more than $3.2 million over the past six months and has more than $2.3 million cash on hand. 

According to the Duggan campaign, more than 93 percent of its donations came from Michigan. Duggan’s campaign manager Ed Duggan also noted that the campaign has raised nearly $1.4 million over the past 30 days alone. 

“As an Independent campaign, we can’t rely on party infrastructure for our fundraising. We had to build everything from the ground up,” Ed Duggan said in a statement. “Our numbers are a sign of the incredible grassroots energy we’re feeling on the campaign trail. We couldn’t be more grateful for all our supporters who made this possible.”

Mike Duggan, who was elected mayor as a Democrat, launched his Independent bid for governor in December.

The mayor’s latest fundraising numbers come a day after Michigan Secretary of State Jocelyn Benson (D), the front-runner in the Democratic primary, announced her campaign raised more than $3.5 million since its launch in January and has more than $2.4 million in the bank. 

Benson’s and Duggan’s hauls are both more than the $1.5 million Gov. Gretchen Whitmer (D), who is term-limited, raised at this point in 2017 after announcing her first gubernatorial bid in January of that year.

In this year’s Democratic primary, Lt. Gov. Garlin Gilchrist II’s campaign said he raised more than $750,000, while former Genesee County Sheriff Chris Swanson said his campaign has raised more than $1 million. Gilchrist jumped into the primary in March, and Swanson announced his bid in February. 

On the Republican side, former state Attorney General Mike Cox (R), who jumped into the race in April, said his campaign has raised $2.4 million and has $1.9 million in the bank. 

Rep. John James (R-Mich.), state Senate Minority Leader Aric Nesbitt (R), and former state House Speaker Tom Leonard (R) are also running in the GOP primary.
