Tennessee's Republican-controlled legislature approved a new congressional map on May 6, 2026, that substantially alters the Memphis-based 9th District by reducing its Democratic core, producing a projected Republican advantage in the general election. Incumbent Democrat Steve Cohen announced on May 15 that he would not seek re-election under the revised lines, leaving Democrats to navigate a crowded August 6 primary that includes state Representative Justin Pearson. Republicans have fielded state Senator Brent Taylor and other contenders for the same primary, capitalizing on the redrawn boundaries that shift the seat from its historical Democratic tilt. Traders have priced the Republican outcome at 81.5 percent, consistent with the map's impact on turnout patterns and the absence of an established Democratic incumbent. The general election remains scheduled for November 3, with ongoing lawsuits challenging the map as a potential variable.
