Upon her election, Blackburn would become the 51st Governor and the first female chief executive in the Volunteer State’s long history. Tennessee became the nation’s 16th state, officially admitted to the Union in 1796.
She must first battle Rep. John Rose (R-Cookeville) who, at this point, is the only other official Republican gubernatorial primary entry. With her strong electoral record and being a fervent Trump supporter, it is hard to see a scenario where she fails to claim the nomination. With Democratic strength at its nadir in the state, it becomes challenging to see how she would have difficulty in the general election.
Only one Republican gubernatorial poll has been published of the race, and that came back in January when Sen. Blackburn began confirming she was considering running for Governor. The Fabrizio Lee & Associates firm released a survey (Jan. 13-16; 800 likely Tennessee Republican primary voters; live interview & text) and the results favored the Senator with a whopping 71-13 percent margin. The poll also found Sen. Blackburn scoring a clear 57 percent majority support figure in Rep. Rose’s 6th District.
Blackburn was originally elected to the Senate in 2018, defeating the state’s former two-term Governor, Phil Bredesen, in the general election by a 55-44 percent count. At the time, it appeared that Bredesen was in the strongest position of any Tennessee Democrat to win the Senate race, but then-Congresswoman Blackburn easily defeated him.
In November, Sen. Blackburn was re-elected in a landslide 64-34 percent victory over Nashville state Rep. Gloria Johnson in a political battle that was never close.
The Senator’s congressional career began with an open-seat victory in western Tennessee’s 7th District 23 years ago. Over her eight US House elections, Blackburn averaged 73.9 percent of the vote and fell below the 70 percent threshold only twice; she ran unopposed once in 2004. Prior to her service in Congress, Blackburn was elected to one four-year term in the Tennessee state Senate.
When talk of Sen. Blackburn running for Governor began, the Republican field was largely frozen, with only Rep. Rose stepping forward to challenge her for the party nomination. Candidate filing in Tennessee for the Aug. 6, 2026, primary ends on March 10, 2026, so much time remains for others to join the race and the situation could change. At this point, however, it appears most of the political jockeying will center around who might be appointed to fill the Senate seat after the new Governor is elected.
Should Sen. Blackburn be successful in her gubernatorial quest, she would be in position to appoint her successor. Since the Senator was just re-elected, the appointed Senator would serve until a special 2028 election would be held to fill the remaining balance of the term. This means the succeeding Senator would assume the office at some early point in 2027 and be eligible to run in the 2028 special election concurrent with the regular election schedule and calendar. The special election winner would then be eligible to seek a full six-year term in 2030.
Blackburn is now the third sitting Senator who has announced plans to enter an open 2026 race for Governor. She joins Sens. Michael Bennet (D-CO) and Tommy Tuberville (R-AL). Of the three, only Sen. Tuberville is risking his seat to enter the state’s gubernatorial campaign.
All three are favored to win their party’s nomination and claim the Governorship in the ’26 general election. Alaska Sen. Lisa Murkowski (R) is also saying she is considering launching a gubernatorial bid.
