**William Lawrence (D) leads trader pricing at 63.5% in the Michigan 7th congressional district race against incumbent Tom Barrett (R) at 37.5%.** The district, centered on Lansing and rated a toss-up by Cook, Sabato, and Inside Elections, flipped to Barrett in 2024 after Elissa Slotkin’s Senate run. Lawrence secured the Democratic nomination in the August 4 primary with roughly 43-44% against two moderates, capitalizing on grassroots organizing, data-center opposition, housing affordability, and climate priorities. Recent activity includes Lawrence’s October town-hall tour and DCCC Red-to-Blue inclusion, while Barrett highlights his military and state-legislative record, police endorsements, and fundraising edge exceeding $6 million. Polling remains tight, with one August survey showing Lawrence ahead by 2 points. Traders appear to weigh the challenger’s primary momentum and district competitiveness more heavily than the incumbent’s structural advantages ahead of the November 3 general election.
