Tennessee's 8th congressional district remains a solidly Republican seat heading into the November 2026 general election, with incumbent David Kustoff positioned as the presumptive nominee after filing as the sole Republican candidate. Recent May 2026 redistricting by the state's Republican supermajority shifted boundaries to incorporate more suburban Memphis areas while preserving a strong overall GOP tilt, as reflected in the Cook Political Report's Solid Republican rating. Multiple Democratic primary contenders are competing for the August 6 nomination, but the district's partisan voting index and historical results limit their general election prospects. Traders have priced in the Republican advantage based on these structural factors, the incumbent's prior 72 percent victory margin, and the absence of competitive challengers or major developments that would alter the race dynamics before the general election.
