Tennessee Just Showed How the Supreme Court’s Redistricting Ruling Works in Practice
Tennessee's Republican legislature on Thursday enacted a new congressional map that carves up the state's only majority-Black House district—becoming the first state to move after last week's Supreme Court decision weakening Voting Rights Act protections.
The new map divides Memphis-based District 9, held by longtime Democratic Rep. Steve Cohen, into three districts that stretch hundreds of miles east into rural Republican territory. The Nashville metropolitan area is further divided into five districts. Governor Bill Lee signed the map into law within hours.
The legislature acted in a special session called by Lee specifically to redraw districts ahead of Tennessee's August 6 primaries. The state House passed the map without a single Republican speaking in its defense. Democrats walked off the floor in protest. Demonstrators in the galleries chanted loudly enough that the House speaker called the vote mid-disruption. Democratic Sen. Charlane Oliver stood on her desk holding a banner calling the redistricting "Jim Crow."
Tennessee is the first domino. Louisiana has already postponed its congressional primary to allow time for a new map. Alabama has legislation awaiting a final vote. South Carolina, prodded by Trump, has taken initial steps. Since Texas redrew its districts last year at Trump's urging, eight states have adopted new congressional maps, with Republicans estimating they could gain up to 13 seats.
## The Power Logic Is Simple
None of this is subtle. The Supreme Court ruled last week that Louisiana relied too heavily on race when creating a second Black-majority district—effectively saying that decades of Voting Rights Act precedent requiring the creation and preservation of minority-opportunity districts was overreaching.
Within days, Tennessee's governor called a special session. The new map was drawn, debated, passed, and signed into law in under a week. The speed is the message: this is not a deliberative process about fair representation. It is a power consolidation exercise with the legal constraint removed.
The structural logic is straightforward. Tennessee has nine congressional seats. Under the current map, eight are held by Republicans and one—the Memphis-based District 9—by a Democrat. The new map is designed to produce nine Republican seats. A state that gave Trump roughly 65% of the vote will have zero Democratic representation in Congress.
What makes this different from ordinary gerrymandering is the combination of speed, coordination, and legal cover. Trump personally urged states to redistrict. The Supreme Court provided the legal opening by gutting the specific Voting Rights Act standard that had preserved majority-minority districts for decades. And state legislatures are moving in sequence, each citing the court's ruling as justification.
This is sovereignty in its rawest form: the power to define who gets represented and who does not. The voters in Memphis's majority-Black community did not change. Their interests did not change. What changed was the legal framework that required their votes to be concentrated enough to elect their preferred candidate.
The design of the new districts tells the story clearly. Districts that once fit geographic communities now stretch across time zones and media markets—Nashville to the eastern mountains, Memphis to rural farmland hundreds of miles away. These shapes make no sense as communities. They make perfect sense as vote-dilution mechanisms.
For the rest of the country, the Tennessee map is a preview. The Southern states moving next all have similar structures: concentrated minority populations in urban areas, Republican-dominated state legislatures, and willing governors. The Supreme Court's ruling removed the main legal tool that prevented exactly this outcome.
The mechanism is neither hidden nor complicated. When the court says race-conscious redistricting is suspect but partisan redistricting is not, and when racial geography and partisan geography overlap almost perfectly, the result is predictable. You can achieve racial vote dilution through partisan line-drawing and claim the intent was merely political.
That distinction—"we're not targeting race, we're targeting Democrats"—is now the legal safe harbor. Tennessee just demonstrated how fast states can exploit it.
