Tennessee voters went to the polls Thursday to settle several high-stakes congressional primaries, the first electoral test of a redistricting cycle that redrew the state's political map to the GOP's advantage—and effectively eliminated the last Democratic seat in the state's House delegation.

The most closely watched contest is in the 5th Congressional District, where President Trump has thrown his weight behind incumbent Rep. Andy Ogles, a Republican. But Governor Bill Lee has broken with the president, endorsing his former state Agriculture Commissioner Charlie Hatcher. That clash sets up a proxy battle over Trump's influence in a district that leans heavily Republican, and the outcome could signal how much weight a presidential endorsement carries in intra-party fights.

Project 2025 co-author placed in Interior watchdog role, Dem charges
Rep. Jared Huffman alleges Dennis Kirk, a Project 2025 co-author, was installed in the Interior Department's inspector general office, potentially compromising its independence.

Ogles, a first-term congressman and former county mayor, has leaned into his Trump alignment, while Hatcher has emphasized his executive experience and ties to the governor. The race has drawn national attention, with outside spending pouring in from both wings of the GOP. A governor's break with Trump over an endorsement is unusual, and it has amplified the stakes for both camps.

In the 9th Congressional District, which covers Memphis, the GOP primary is wide open after longtime Democratic Rep. Steve Cohen announced his retirement following nearly two decades in office. Cohen, the state's only Democratic House member, saw his district redrawn by Republican lawmakers to include more conservative suburbs, a move widely seen as an effort to flip the seat. State Sen. Brent Taylor has secured Trump's endorsement and leads a crowded field that includes state Sen. Todd Warner, retired Army Sgt. Jeremy Thompson, and businesswoman Charlotte Bergmann.

The redistricting process itself has been a flashpoint nationally. Similar fights have erupted in other states, with courts and legislatures clashing over maps. In Missouri, for instance, officials blocked a referendum on a Trump-backed map, while in Maryland, Governor Moore has backed national reform even as he signed a new map. Tennessee's map, drawn entirely by Republicans, has been criticized by Democrats as a partisan gerrymander, but it has withstood legal challenges.

Polls closed at 8 p.m. EDT, with results expected shortly thereafter. Turnout was reported to be moderate, with early voting numbers suggesting strong interest in the 5th District race. Both campaigns had urged supporters to turn out, and the outcome could hinge on which faction—Trump's base or the governor's establishment wing—is more energized.

The broader implications extend beyond Tennessee. The GOP's redistricting advantage has been a key factor in the party's efforts to maintain control of the House, and races like these will determine which Republicans advance to the general election in November. A win for Hatcher would be a rare rebuke of Trump's endorsement power, while a Taylor victory in the 9th would set up a likely GOP pickup in a district that has been Democratic for decades.

For Democrats, the loss of Cohen's seat—whether in the primary or the fall—would mark a significant setback in the South. The party has struggled to compete in the region, and the redrawn lines in Tennessee underscore the challenges ahead. Some Democrats are looking to internal battles within their own party as a sign of the broader struggle to define a winning message.

As the night unfolds, all eyes will be on the 5th and 9th districts. The results will not only shape Tennessee's congressional delegation but also offer a fresh gauge of the political currents running through the GOP ahead of the midterms.
