Michigan Senate Polls: Late Macomb County Surge Threatens Gary Peters
A late surge for Republican challenger James Vance in Macomb County has cut into Democratic Senator Gary Peters’ lead just days before the election.
With just seventy-two hours left before polls open, Michigan’s high-stakes Senate race has tightened into a dead heat. Incumbent Democratic Senator Gary Peters is clinging to a razor-thin lead. But a late-breaking surge for his Republican challenger, wealthy businessman James Vance, has sent shockwaves through Democratic circles. The epicenter of this shift is Macomb County, the historic bellwether that’s long decided statewide elections in the Great Lakes State.
According to the latest Epic-MRA poll released Saturday morning, Peters holds a narrow two-point lead over Vance, leading 47% to 45% statewide. That’s well within the margin of error. Just ten days ago, the same poll showed Peters up by a more comfortable five points. The sudden tightening is almost entirely driven by working-class voters in Detroit’s northern suburbs.
The Macomb County Shift
Macomb County has always been a political battleground. Famous as the birthplace of the “Reagan Democrats,” its voters are notoriously independent. They lean conservative on social issues but remain fiercely protective of labor and manufacturing.
The new data shows Vance leading Peters by nine points in Macomb, a major jump from his three-point lead in the county earlier this month. This late momentum suggests that Vance’s relentless focus on economic anxiety is hitting home.
“We are seeing a massive wave of undecided voters breaking toward Vance in the final stretch,” said veteran Michigan pollster Richard Czuba. “These are people who feel left behind by the current economy. They worry about the future of the auto industry and the cost of everyday goods. Right now, they want a change.”

Vance has spent millions on television ads targeting Macomb County families. His campaign has hammered Peters on inflation and federal electric vehicle mandates. It’s a message tailored specifically to the thousands of auto workers who call Macomb home.
Two Campaigns, Two Different Paths
For Peters, the path to victory has always relied on a massive turnout in Wayne and Oakland counties, combined with strong support in college towns like Ann Arbor and East Lansing. His campaign isn’t panicking, but the latest numbers have certainly increased the urgency.
At a rally in Warren on Friday afternoon, Peters stood alongside union leaders, urging supporters to get to the polls early. He warned that a Republican-controlled Senate would roll back protections for workers and cut funding for local infrastructure.
“This race is about who actually has your back when the chips are down,” Peters told the crowd. “We’ve brought manufacturing jobs back to Michigan. We’ve protected pensions. We can’t afford to hand the keys over to a corporate executive who wants to undo all that progress.”
Meanwhile, the Vance campaign is radiating confidence. They believe the momentum is entirely on their side. Vance spent his Saturday morning greeting voters at a diner in Sterling Heights, where he promised to bring a business-minded approach to Washington.

“The career politicians have had their turn, and look where it got us,” Vance said in an interview after the event. “People are tired of struggling to pay for groceries while Washington spends trillions. Macomb County is ready to send a message, and we’re going to win on Tuesday.”
The Ground Game in the Final 72 Hours
With the race this close, the outcome will likely come down to ground operations. Both parties are pouring unprecedented resources into get-out-the-vote efforts.
- Democrats are focusing heavily on mobilizing Detroit’s Black voters, a crucial constituency that Peters needs in high numbers to offset losses in rural areas and Macomb County.
- Thousands of volunteers are knocking on doors across the city, coordinating rides to early voting locations, and reminding residents of what’s at stake.
- Republicans are countering with an aggressive chase of absentee ballots and a massive push for in-person voting on Tuesday.
- They’re targeting conservative strongholds in western and northern Michigan, while hoping the Macomb surge holds through Election Day.
This late scare is a familiar feeling for Peters. Back in 2020, he narrowly survived a challenge from Republican John James, winning by less than two percentage points. That race also saw a late surge from the Republican challenger that caught Democrats off guard. History seems to be repeating itself, and Peters is leaving nothing to chance this time around.
The stakes couldn’t be higher. Control of the U.S. Senate may very well hinge on Michigan. If Vance pulls off the upset, it would represent a major blow to Democrats and a sign that the political realignment of working-class voters is continuing to accelerate.
For now, both candidates are living on the road. They’re crisscrossing the state, chasing every last vote. But all eyes remain fixed on Macomb County. Whichever way those suburban voters swing on Tuesday will likely determine who represents Michigan in Washington for the next six years.
