Detroit Mayor Mary Sheffield endorsed Michigan Secretary of State Jocelyn Benson for governor on June 15, 2026, lending the Democratic front-runner one of Sheffield’s first formal endorsements since taking office. The announcement adds notable local momentum to Benson’s campaign as the 2026 primary season advances.
Why It Matters
Sheffield’s support carries symbolic and political weight in Michigan’s largest city. Detroit’s voters are a critical constituency in any Democratic primary, and Sheffield — who succeeded Mike Duggan as mayor — has been deliberate about how she uses her endorsement power. Her decision to back Benson signals alignment on a range of urban policy priorities, from prescription drug access to housing costs.
Sheffield emphasized that major decisions affecting Detroiters ultimately flow through the state capitol. “A lot of the issues that you all care about…all of these things go through Lansing,” she said at a joint press conference with Benson.
What Happened
Sheffield announced her support for Benson at a press event, citing three policy areas as central to her decision: a proposed statewide expansion of Rx Kids, property tax reform, and affordable housing initiatives. Sheffield launched Rx Kids — a program providing cash assistance to families with young children — in Detroit early in her administration, and she pointed to Benson’s commitment to scaling that program across Michigan as a key factor in winning her backing.
Benson, who has been campaigning for roughly a year and a half, welcomed the endorsement as part of a broader coalition-building effort. “We’re going to be doing events like this all across the city, and really demonstrating that power of sisterhood, that power of friendship,” Benson said.
The Primary Field
Benson enters the endorsement with a commanding position in the Democratic primary. Her only declared opponent is Genesee County Sheriff Chris Swanson, whose profile remains significantly lower in the race. The field took on a different shape weeks earlier when former Detroit Mayor Mike Duggan withdrew from an independent gubernatorial bid, removing a candidate who could have complicated general-election dynamics for Democrats.
Sheffield’s predecessor, Duggan, had positioned himself outside the Democratic Party structure during his gubernatorial campaign before stepping aside. Sheffield’s endorsement of Benson effectively consolidates Detroit’s Democratic establishment behind the Secretary of State heading into the primary.

What’s Next
Benson indicated the Detroit press conference is one of several planned events aimed at building visible coalitions ahead of the primary. Expanding the Rx Kids model statewide would require legislative action and funding mechanisms to be worked out in Lansing — making the governor’s office central to any such effort. Property tax relief and affordable housing proposals face similar pathways through the state legislature.
As endorsements continue to accumulate and advertising campaigns take shape, the Democratic primary will test whether Benson’s early advantages in name recognition and institutional support translate to a strong primary performance. Michigan’s political landscape in 2026 also includes ongoing intraparty tensions, including disputes over Democratic Party processes that have drawn attention in recent months.
