The Tennessee Republican primary handed President Donald Trump a mixed result Thursday night, with one endorsed candidate cruising to victory and another losing his seat outright. It was also the state’s first election run under a redrawn congressional map built to help the GOP pad a narrow House majority.

The night’s biggest surprise came in the 5th District, where former Agriculture Commissioner Charlie Hatcher unseated two-term Rep. Andy Ogles despite the president’s public backing.

An Incumbent Falls Despite Heavy Support

Ogles was not lacking for allies. A member of the House Freedom Caucus, he carried endorsements from both Trump and House Speaker Mike Johnson, and Trump personally stepped in as the contest tightened, hosting a virtual tele-rally last month where he praised Ogles as a capable businessman and a committed America First legislator.

It was not enough. Hatcher, who had the support of term-limited Gov. Bill Lee, pulled off the upset.

The Money That Shaped the Race

A significant outside effort worked against Ogles throughout the campaign.

The Invest in Tomorrow Coalition, a clean-energy super PAC funded largely by California crypto billionaire and prominent Democratic donor Chris Larsen, put roughly $1 million into opposing Ogles and boosting Hatcher. Federal filings reviewed ahead of the vote showed an additional $700,000 in advertising purchased in the closing stretch.

Ogles offered his own reading of why he had been targeted. He argued the group was retaliating for his opposition to clean-energy subsidies enacted under President Joe Biden, and suggested his proximity to Trump made him a more attractive target.

The New Map Worked Against Him Too

There was a second factor working against the incumbent, and it was one his own party created.

Tennessee Republicans overhauled the 5th District this spring. The redraw made the seat considerably safer for a Republican in the general election, but it also handed Ogles a primary electorate substantially different from the one that had sent him to Washington twice before. Familiarity is an incumbent’s greatest asset, and much of it was redrawn away.

The Memphis Seat Becomes a National Battleground

The redistricting effort went well beyond one district. Republicans dismantled the Democratic-held 9th District, positioning the party to convert its current 8-1 advantage in the state delegation into a complete 9-0 sweep.

The consequences were immediate. Longtime Democratic Rep. Steve Cohen abandoned his reelection campaign after his Memphis-area district was transformed from reliably Democratic into territory that now leans Republican.

Thursday’s results set up a general election contest with unusually clear ideological lines:

• Brent Taylor, a state senator carrying Trump’s endorsement, won the Republican nomination
• Justin Pearson, a progressive state representative backed by Rep. Alexandria Ocasio-Cortez and allies in the House’s left flank, took the Democratic nomination

Pearson brings national recognition of his own. He was one of the lawmakers known as the Tennessee Three, expelled from the legislature in 2023 following a gun control protest, an episode that drew attention far beyond the state.

Taylor now carries the burden of delivering the seat that would complete the Republican sweep. Pearson’s task is to hold a Democratic presence in Memphis on a map deliberately engineered against him.

Blackburn Clears Her Path to the Governor’s Mansion

In the other headline race, Sen. Marsha Blackburn defeated Rep. John Rose to win the Republican nomination for governor, succeeding the term-limited Lee.

In a heavily Republican state, that nomination puts her in strong position for November. Winning would make her the first woman to serve as Tennessee’s governor.

Her statement after the results leaned into the framing she has used throughout the campaign. She thanked voters, described the effort as a year-long push to establish Tennessee as the country’s conservative standard-bearer, and said she felt humbled by the nomination before turning attention to the general election.

A Senate Vacancy Waiting in the Wings

Blackburn’s campaign carried a structural advantage that her opponent lacked. Reelected to a six-year Senate term in 2024, she did not have to give up her seat to run for governor. Rose, holding a House seat on a two-year cycle, did.

That advantage comes with a delayed cost. If she wins in November, she must resign from the Senate, opening a vacancy in Washington and triggering a fresh round of maneuvering over who fills it.

For a state already reshaping its House delegation, that would add one more moving piece to an unusually eventful political year.

What Thursday Actually Showed

The results complicate any simple story about the president’s influence over Republican primaries.

Trump’s endorsement carried Taylor through in the 9th District. It did not save Ogles in the 5th, where a well-funded outside campaign and a redrawn electorate combined to overcome it.

The lesson may be less about the strength of an endorsement than about its limits. Where a race is otherwise close and the terrain has shifted underneath an incumbent, presidential support functions as one factor among several rather than a decisive one.

Tennessee Republicans still enter November with a map designed to deliver every seat in the state. Whether it does will be settled in Memphis.
