Tennessee's congressional map, redrawn by the Republican-controlled legislature in 2026 following a Supreme Court decision, dismantled the state's sole Democratic-leaning district centered in Memphis and redistributed voters across boundaries that produce Republican advantages of 10 points or more in every seat. All nine districts now carry solid or likely Republican ratings from nonpartisan analysts, with forecasts projecting zero Democratic victories even amid a national environment tilted toward Democrats. Recent polls in the most competitive races, including the open 5th and 9th districts, show Republican nominees maintaining double-digit or high-single-digit leads, consistent with the state's overall partisan lean and turnout patterns. This structural positioning underpins the market's heavy weighting toward zero Democratic seats, as traders assess limited pathways for gains despite candidate recruitment and modest polling movement in targeted areas.
