The Michigan-12 House race shows Person A and Person B locked at 50% each, reflecting trader consensus on evenly matched candidates in a district with longstanding Democratic structural advantages. Highest probabilities cluster on Democratic margins of 45-60%, consistent with the seat's urban-suburban composition and recent midterm turnout patterns, while Republican wins sit near zero. The split pricing across margin buckets signals uncertainty over final vote share driven by localized factors such as economic messaging, early voting volume, and mobilization in key precincts ahead of election day. Late shifts in turnout or ballot counting could still widen or narrow the outcome within the resolution window.
