Christina Hines holds a clear edge in the MI-10 House race, an open swing seat covering southern Macomb County and parts of Oakland County previously held by Republican John James, who is running for governor. Hines secured the Democratic nomination in the August 4 primary with roughly 47 percent of the vote against two challengers, while Trump-endorsed Republican Michael Bouchard won his primary decisively at 72 percent. A late-August poll showed the candidates tied at 45 percent, though some forecasters rate the contest a toss-up or lean Republican. Hines launched her first television ad in early September emphasizing her background as a former prosecutor and mother of three, highlighting cost-of-living and family issues. Traders appear to view the suburban district's demographics and midterm dynamics as favoring the Democrat heading into the November 3 general election.
