Tennessee Republicans passed a new congressional map Thursday that dismantles the state's lone majority-Black congressional district, NBC News reports. The redrawn lines position Republicans to capture an additional House seat and consolidate full control of Tennessee's congressional delegation.

Tennessee is now the ninth state to enact a revised congressional map ahead of the 2026 midterms — a coordinated national pattern that deserves to be read as exactly that: a pattern.
What Tennessee just did is textbook racial cracking: take a geographically concentrated Black voting population, split it across multiple majority-white districts, and dilute it below the threshold at which it can elect a representative of its choice. The legislature doesn’t have to say the quiet part out loud. The map does the work.
This technique is not new. It is, in fact, one of the oldest tools in the American gerrymandering arsenal. After Reconstruction collapsed in the 1870s, Southern legislatures spent the better part of a century perfecting exactly this method — carving Black neighborhoods into multiple white-majority districts — to ensure that the Fifteenth Amendment’s guarantee of voting rights produced no actual representation. The Voting Rights Act of 1965 was designed specifically to break that cycle, requiring states with histories of discrimination to preclear map changes with the federal government before they took effect.
That preclearance requirement — Section 5 of the VRA — is gone. The Supreme Court gutted it in Shelby County v. Holder (2013), ruling that the coverage formula identifying which states needed oversight was outdated. Within hours of that decision, several covered states — including Texas — moved to implement maps and voter ID laws that had previously been blocked. Tennessee, though not a covered state under the original formula, operates in the political world that Shelby created: one where the deterrent effect of federal oversight has been substantially removed.
Tennessee is now the ninth state to enact a new congressional map for 2026. That number matters. Mid-decade redistricting of this kind — outside the normal post-census cycle — is itself unusual and worth naming. The standard practice is to draw maps once per decade, after the census, and live with them. What we are watching instead is a coordinated Republican effort to redraw maps in states where legislatures believe they can improve their position before the next census arrives.
Alabama’s resistance to court-ordered majority-Black districts, Louisiana’s drawn-out legal fight over a second Black-majority seat, and now Tennessee’s erasure of its only such district are not isolated events. They form a single strategic project: maximize white Republican representation in the South before demographic shifts make it permanently harder to do so.
Section 2 of the Voting Rights Act — the remaining enforcement mechanism — prohibits maps that deny or abridge the right to vote on account of race. Litigation is almost certain. But Section 2 cases move slowly, often on timescales measured in years rather than election cycles. Alabama’s redistricting litigation stretched across two election cycles before the Supreme Court finally ordered a remedial map in Allen v. Milligan (2023) — and even then, Alabama’s legislature initially defied the order.
The lesson of that timeline is that a map can do its political work — electing Republicans who would otherwise lose, extinguishing Black representation for a cycle or two — long before the courts impose a remedy. The wrong, if it is ultimately adjudicated as one, will have already produced its intended electoral effect.
Watch whether the Department of Justice files a Section 2 challenge, and watch how quickly any such challenge moves. Watch whether Tennessee’s new map produces the predicted Republican pickup in 2026. And watch whether the total count of mid-decade Republican remaps climbs past nine — because the willingness to redraw maps between censuses, without legal compulsion, is itself a constitutional norm being eroded in real time.
