Sen. Marsha Blackburn, R-Tenn, won the Republican nomination Thursday night for Tennessee governor, defeating Tennessee GOP Rep. John Rose for the party's nomination. Blackburn is running to replace Republican Gov. The senator defeated Rose 43.9% to 32.7%, while state Rep. Monty Fritts came in third with 23.3% of the vote, according to the Associated Press. Blackburn was only reelected to the Senate in 2024, meaning her full-term is not up until 2031. But if Blackburn wins in November, Lee will select a replacement to fill the seat until the state's next general election.
