Michigan's 7th congressional district, centered on the Lansing-East Lansing area with portions of surrounding counties, remains a competitive swing district. Republican incumbent Tom Barrett flipped the seat in 2024 with a narrow 50.3% margin after previous Democratic control. The August 4 Democratic primary features leading candidate Bridget Brink, a former U.S. ambassador to Ukraine, ahead in recent polling against other contenders. Traders assign the Democratic Party a 67% implied probability of winning the November 2026 general election, reflecting the district's toss-up status, historical voting patterns, and typical midterm dynamics challenging the incumbent party. The Republican primary features Barrett seeking renomination in a race still viewed as winnable by either side depending on nominee strength and turnout.
