Scott DesJarlais holds a commanding position in the TN-04 House race due to the district’s strong Republican partisan lean, his status as incumbent, and a substantial fundraising edge over challenger Victoria Broderick. The seat’s underlying voter composition, reflected in presidential results and modeled leans around R+20, has produced consistent Republican margins even after 2026 redistricting added a portion of Davidson County. DesJarlais secured his party’s nomination with 66 percent in the August primary, while Broderick advanced with under 38 percent on the Democratic side, and no public polls show movement toward competitiveness. Race ratings classify the contest as safe or solid Republican. An upset would require an unforeseen late development such as a major scandal, health event, or turnout surge exceeding historical patterns in the redrawn areas.
