Redistricting in May 2026 altered Tennessee’s 9th Congressional District boundaries, prompting longtime incumbent Steve Cohen to withdraw and leave the Democratic primary open. This shift elevated state Representative Justin Pearson, who announced his continued candidacy and draws support from progressive networks and local visibility in the Memphis area. Activist DeVante Hill remains in contention after ballot-access issues were resolved by the state party, while other entrants such as state Senator London Lamar add to the field. Traders assign Pearson the highest probability at 56.5 percent, Hill 10.6 percent, and Cohen 4.3 percent, reflecting the impact of the open-seat dynamic, candidate filing timelines, and limited recent polling data ahead of the August 6 primary.
