The open seat in Michigan’s 10th congressional district, created by Republican incumbent John James’s decision to run for governor, has produced a competitive general-election matchup between Democratic nominee Christina Hines and Republican nominee Michael Bouchard following the August 4 primaries. The district, anchored in Macomb County with portions of Oakland County, remains a swing area that supported Donald Trump by seven points in 2024 yet features closely divided voter blocs and a history of narrow House margins. Limited public polling shows a tight race, but trader consensus on prediction markets prices Hines ahead at 68.5 percent, citing the absence of the prior incumbent’s personal support, the candidates’ respective profiles as a local prosecutor and an Army veteran, and the broader midterm environment ahead of the November 3 general election.
