Sen. Marsha Blackburn (R-Tenn.) has secured the Republican nomination for Tennessee governor, according to Decision Desk HQ, putting her on a clear path to succeed term-limited Gov. Bill Lee (R) in the Volunteer State's top office.
Blackburn defeated Rep. John Rose (R-Tenn.) in Tuesday's primary, a race that saw both candidates align themselves with President Trump's agenda in a state the president carried decisively in 2016, 2020, and 2024. The victory was widely expected, as internal polling published in The Tennessean in July showed Blackburn holding a commanding 31-point lead over Rose, 51% to 20%.
Rose's campaign struggled to gain traction despite his heavy personal investment. He self-funded roughly 85% of his bid, a fact that became a focal point for Blackburn's team. Ward Baker, a strategist for Blackburn, told The Tennessean that the governor's office “is not for sale,” a direct jab at Rose's personal spending.
Blackburn's entry into the race came after months of speculation. She mulled a gubernatorial run in January 2025 before officially launching her campaign in July. In her announcement, she vowed to transform Tennessee into a national “powerhouse” for job creation and energy production, while also championing parental rights in education and promising to deport undocumented immigrants.
“This is Tennessee,” Blackburn said in her campaign launch video. “We’ll honor the Constitution, we’ll value life, and we’ll define our boys and girls the way God made them. I love Tennessee. I believe in Tennesseans, and I’m ready to deliver the kind of conservative leadership that will ensure our state is America’s conservative leader for this generation and the next.”
Blackburn, who first won her Senate seat in 2018 after serving 16 years in the House representing Tennessee’s 7th Congressional District, enters the general election with significant institutional backing. She has secured endorsements from several Tennessee GOP lawmakers, including Reps. Tim Burchett, Chuck Fleischmann, Matt Van Epps, and former Rep. Jimmy Duncan.
If victorious in November, Blackburn would make history as the first woman to serve as Tennessee’s governor. She is set to face Memphis City Council member Jeri Green, who is projected to win the Democratic primary on Thursday. The general election will also likely draw attention to other races in the state, including the Tennessee Senate race, where a rematch between Bill Hagerty and Marquita Bradshaw is shaping up.
Blackburn's primary win also underscores the continued influence of Trump in Tennessee politics, a theme echoed in the broader primary landscape. Her campaign's focus on conservative cultural issues and immigration aligns closely with the president's platform, which resonated strongly with the state's GOP electorate.
As the general election approaches, Blackburn is expected to leverage her national profile and fundraising network against Green, a relative newcomer to statewide politics. Political analysts will be watching whether her emphasis on issues like energy independence and border security can translate into a broad coalition in November, particularly in a state that has not elected a Democratic governor since 2006.
