Tennessee’s sole congressional Democrat won’t run again after redistricting - The Washington Post

Rep. Steve Cohen announced he will not seek reelection after his majority‑Black district in Tennessee was broken up into three Republican‑leaning districts, a direct consequence of recent redistricting. That decision mirrors the higher‑stakes dynamic described in the Philadelphia primary story, where weakened Voting Rights Act protections and aggressive mapmaking are reshaping who runs and which seats remain competitive. Cohen’s retirement is an example of how redraws are producing immediate political fallout for incumbents and the balance of representation.
