Johnny Garrett secured the Republican nomination for Tennessee’s 6th congressional district after winning the August 2026 primary with 43.6% of the vote in an open-seat contest following incumbent John Rose’s gubernatorial bid. The district, redrawn in 2026 and stretching from eastern Nashville suburbs across the Cumberland Plateau, has favored Republicans in recent cycles and carries solid or safe Republican ratings from multiple forecasters. Garrett’s background as state House Republican whip and endorsements from national GOP figures have reinforced his position ahead of the November general election. Democrat Mike Croley, who advanced from a fragmented primary, faces structural headwinds in the solidly Republican territory. Scenarios that could narrow the gap include unusually low Republican turnout, a major late-campaign development, or significant independent vote consolidation, though no such shifts have materialized in the weeks since the primaries.
