Tennessee’s heavily engineered congressional maps held up last week, but with smaller margins than in previous election cycles, according to an analysis of election data by Lookout.
Republicans secured roughly 54% of the vote across Tennessee’s nine congressional races while capturing eight of those seats, which translates to 89% of the total delegation. In the state House, GOP candidates garnered 58% of the ballots cast and claimed 69 out of 99 districts, or 70% of the chamber.
Those outcomes stem from a strategic redrawing of the state House map in 2022 and a U.S. House map enacted during a May legislative session. The resulting districts diluted Democratic voting strength, though Democratic candidates still managed to capture 44% of congressional votes and 41% of state House votes statewide.
Margin compression defined this cycle’s congressional contests, particularly in districts 5 through 9. While Republicans handily swept eight of the state’s nine U.S. House seats during the 2022 and 2024 elections, mid-cycle adjustments narrowed those winning margins significantly.
Democratic challengers lost those five specific districts by less than 5% this year. That represented a sharp shift from 2024, when President Donald Trump carried those same districts by margins of 20% to 25% over Democratic Vice President Kamala Harris. A broader political tailwind also bolstered those tallies, as Democrats won the national popular vote by 13%, contrasting with a 1.5% loss in 2024.
“Tennessee was an afterthought, but this is what can happen in wave elections,” Kent Syler, a political science professor at Middle Tennessee State University, said.
The newly drawn map allowed Republicans to flip the 9th Congressional District, formerly held by Memphis Democratic U.S. Rep. Steve Cohen. Yet the party likely lost the 4th Congressional District, leaving the overall partisan balance of the state’s federal delegation numerically unchanged.
Democrat Victoria Broderick holds a narrow lead over U.S. Rep. Scott DeJarlais in the 4th District by roughly 285 votes, though election officials have not officially called the contest. Approximately 700 provisional ballots remain uncounted in that district as of Nov. 12, with about 600 located inside the Democratic stronghold of Nashville, where Broderick secured roughly 75% of the vote on election night.
Election workers will process those remaining ballots on Monday, Nov. 16, after which authorities can likely certify the outcome. If Broderick maintains her advantage, her victory will stand as the sole Democratic win on Tennessee’s congressional map, effectively neutralizing the legislative intent behind the redraw.
Meanwhile, Democrats made headway in the state legislature by flipping six lower-chamber seats. The party secured 29 official seats in the state House, though that count could rise to 30. In a Memphis district, the death of Democratic incumbent G.A. Hardaway left neither major party with a nominated candidate, allowing write-in contender John Bradley to win the seat.
