William Lawrence holds a 61.5% implied probability in the MI-07 House race against incumbent Tom Barrett at 38.5%, reflecting trader assessment of a narrow Democratic edge in this Lansing-area toss-up district. Lawrence secured the Democratic nomination in the August 2026 primary by defeating two more moderate challengers with strong grassroots turnout and endorsements from Senator Bernie Sanders and labor groups. The district’s even partisan lean, combined with Lawrence’s addition to the DCCC Red to Blue program and focus on local issues like data centers and housing costs, has boosted his positioning. Barrett maintains advantages in fundraising, military record, and recent Republican endorsements including from House Speaker Mike Johnson, though polling averages remain close and forecasters rate the contest a toss-up heading into November 3.
