Republican U.S. Sen. Marsha Blackburn announced Wednesday that she is entering the open Tennessee governor’s race in 2026, setting up a primary clash with U.S. Rep. John Rose.
Blackburn’s announcement makes official what had been expected for some time from the ally of President Donald Trump. She had made no secret that she was planning on running for the position.
It sets up a Republican primary clash in August 2026 against Rose who is also a Trump backer. They will be competing to replace GOP Gov. Bill Lee, who is hitting his limit of two four-year terms in office.
Blackburn won her Senate seat in 2018 by nearly 11 percentage points over Democrat Phil Bredesen, a popular former governor. That victory marked a rightward shift from previous Republican senators who has represented the state. She then won reelection against Democratic state Rep. Gloria Johnson by more than 29 percentage points last November.
First elected to the U.S. House in 2002, Blackburn aligned with the tea party movement and regularly appeared on Fox News. Before that, the Brentwood resident made a name for herself as a state lawmaker who helped lead the revolt against a proposed Tennessee income tax in the early 2000s.
In an opening campaign ad, Blackburn lauded Trump, promised leadership in job creation and energy production and hit on timely conservative themes — for example, empowering parents in education, defining “boys and girls the way God made them,” and deporting immigrants in the country illegally, “whether it takes planes, trains or starships.”
“In his first six months, President Trump has made historic strides in Making America Great Again, but as he sends power back to the states, he’s going to need strong conservative governors who can bring that revolution home,” Blackburn said in an announcement news release. “I’m running to serve as Tennessee’s next governor to ensure Tennessee is America’s conservative leader.”
Rose, who announced his bid for governor in March, likewise has voiced strong support for Trump in a state that Trump has easily won in the past three presidential elections. Trump won Tennessee in 2024 by nearly 30 points and Lee defeated a Democratic opponent in 2022 by 32 percentage points.
Blackburn’s prior statements about considering a bid for governor scared off some prominent Republicans who may have otherwise run.
Rose, a Cookeville businessman and farmer who can tap into personal wealth, lent his campaign $5 million and raised $1.1 million from donors through June.

Several Democrats have announced or opened fundraising accounts for the race so far. They include Memphis city councilmember Sherri Green, Memphis community advocate Carnita Atwater, musician Adam “Ditch” Kurtz and Tim Cyr from Gallatin.
