The Tennessee Republican-led Senate and Gov. Bill Lee approved a new congressional map on Thursday that dismantles the state's only majority-Black district [1].

This redistricting effort fundamentally alters the electoral landscape of the state. By splitting the 9th Congressional District, the map removes a reliable Democratic stronghold and redistributes those voters into areas where Republican candidates hold a significant advantage [2].

The 9th District, which is centered on Memphis, had served as the only majority-Black district in Tennessee [1]. Under the new map, this district is split among several Republican-leaning districts [3]. The move follows a recent U.S. Supreme Court ruling that removed specific Voting Rights Act protections for majority-minority districts [4].

Republicans in the state legislature said the goal is to ensure a GOP advantage in all nine [2] of Tennessee's House seats. The approval took place at the state Capitol in Nashville and has sparked immediate protests and sharp debate among lawmakers [5].

Opponents of the map said the move intentionally dilutes the voting power of Black citizens in Memphis. By fragmenting the 9th District, the new boundaries make it more difficult for minority communities to elect a representative of their choice. This shift effectively erases the state's lone majority-Black representation in the U.S. House of Representatives [3].

Gov. Bill Lee signed the map into law following the Senate's approval. The timing of the vote on May 7 [6] places the new boundaries in effect ahead of upcoming election cycles, ensuring the GOP can leverage the new map to secure more seats in the congressional delegation [4].

“The new map gives Republicans an advantage in all nine of the state's House seats”

This redistricting reflects a broader national trend where state legislatures are leveraging Supreme Court precedents to weaken minority-majority districts. By dismantling the 9th District, Tennessee Republicans are not only seeking a mathematical advantage in the U.S. House but are also testing the limits of the Voting Rights Act in the post-Supreme Court ruling era.
