Tennessee's 8th congressional district remains a solidly Republican seat held by incumbent David Kustoff, who ran unopposed in the August primary while Democrat Heidi Kuhn won her party's nomination. Historical margins in the district have ranged from roughly 16 to 20 points in recent cycles, and forecasters rate the general election as safe Republican with no competitive polling available this cycle. The clustered pricing across Republican margin buckets reflects uncertainty over turnout, the national midterm environment, and independent candidates' potential impact on vote share. Traders appear to view the precise margin as variable within a typical range for the district, while assigning low probability to a Democratic victory given the partisan lean and Kustoff's institutional support. Scheduled events such as early voting beginning in mid-October could provide additional signals ahead of the November 3 general election.
