Redistricting Shakes Tennessee Primaries as Incumbent Ogles Loses and New Maps Test GOP Strength

In Tennessee’s Thursday primary, incumbent Republican Andy Ogles lost his seat to challenger Charlie Hatcher, marking the first major test of the state’s newly drawn congressional map. The map was redrawn in May after the US Supreme Court weakened protections for minority voters under the Voting Rights Act, allowing Republican lawmakers to reshape districts. Tennessee was one of roughly ten states that reconfigured its map since 2025 as part of a partisan push to gain an advantage in the 2026 United States midterm election.

Each district on a congressional map translates to one seat in the House of Representatives, and how a district is drawn can affect who is ultimately elected. With Republicans holding a slim majority in the House, the chamber is considered vulnerable to flip to Democratic control. The new congressional map, redrawn in May after the Supreme Court weakened Voting Rights Act protections, dismantled the state’s sole majority‑Black district in Memphis, a longtime Democratic stronghold. Republicans already hold eight of the state’s nine congressional seats and are aiming for a clean sweep of all districts in November.

The primary results set the stage for those midterm showdowns by finalising the Democratic and Republican nominees for November’s ballot. In District 5, former Agriculture Commissioner Charlie Hatcher defeated Trump‑endorsed incumbent Andy Ogles, who had faced criticism for anti‑Muslim remarks. Ogles has represented Tennessee’s 5th District since 2023. In a March social media post he wrote, “Muslims don’t belong in American society. Pluralism is a lie.” Hatcher, a fifth‑generation Tennessee dairy farmer who publicly supports Trump, will face Democrat Chaz Molder in the general election.

In the governor’s race, Senator Marsha Blackburn defeated US Representative John Rose to clinch the Republican nomination. Blackburn is racing to succeed Governor Bill Lee, who is barred by term limits from seeking re‑election. In November, she will face Memphis City Council member Jerri Green, who won the Democratic primary. Blackburn enters the general election with a significant partisan advantage in a state that has become one of the Republican Party’s most consistent strongholds; Republicans have held the governor’s office since 2011 and won every US Senate election in Tennessee since 1994. If elected, Blackburn would become Tennessee’s first female governor.

The primaries also highlighted the battle for District 9, where the new map has set up a heated contest after breaking apart the Memphis‑based majority‑Black district. While no incumbent appeared on the ballot in that district, the reshaped boundaries are expected to influence voter alignment and party fortunes in November. By weakening the Democratic‑leaning Memphis‑based district and creating more Republican‑tilted seats, the map may help the GOP protect its House majority and pursue a sweep of Tennessee’s congressional seats. Conversely, Democrats will need to overcome the structural shifts in Districts 5, 6 and 9 to make gains in November. The primaries thus serve as an early indicator of how redistricting, driven by partisan strategy, could shape the balance of power in the upcoming midterm elections.

Observers will watch the November results to see whether the new lines hold.
