Blackburn Wins Tennessee Governor's Race as Democrats Flip Five Counties

Republican candidate Marsha Blackburn won the Tennessee governor's race in the 2026 midterms, becoming the first woman to hold the office. She will be sworn in this January. The victory came despite a shift in voting patterns that saw Democratic margins expand in every county across the state compared to the 2024 presidential election.

Unofficial election results from the Tennessee Secretary of State’s Office indicate that five counties flipped from red to blue in the gubernatorial contest. Madison, Montgomery, Hamilton, Knox, and Rutherford counties all voted for Democrat Jerri Green. This stands in contrast to the 2024 cycle, where those areas supported the Republican ticket. The data suggests a growing Democratic base even in a state that remains predominantly red.

The expansion of Democratic support was most pronounced in urban centers. Associated Press statistics show that Davidson County saw a 25.6-point rise in votes for Democratic candidates compared to 2024. Williamson County, a traditional Republican stronghold, also experienced a 17.6-point increase for Democrats. These shifts occurred even as the majority of the state’s counties remained red, with no counties flipping from blue to red in the governor's race.

Maury County illustrates the changing margins in traditionally Republican areas. In 2024, 72% of residents voted Republican and 27% voted Democrat. In the 2026 midterm election, the split moved to 54% Republican and 33% Democrat. This represents a 21-point shift toward Democrats in a county that previously showed a wide Republican advantage. The AP data confirms that all Tennessee counties moved in this direction.

Two U.S. House seats changed hands in the newly redistricted map. Republicans gained control of U.S. House District 9. Democrats flipped District 4. These two turnovers occurred against a backdrop where the GOP held all but one congressional district before the election. The results reflect a competitive environment in specific districts despite the overall Republican hold on the governor's mansion.

The governor's race was closer than polls predicted. The lead changed between Blackburn and Green for hours on election night. This tight contest contradicted forecasts that showed a wider margin for the Republican candidate. The closeness highlighted the pressure on the Republican party's traditional hold on Tennessee politics, which has controlled the governor's office for 15 years. The last Democrat to hold the post was Phil Bredesen, who served from 2003 to 2011.

Vice President JD Vance attributed the party's mixed results to the ongoing war in Iran. He stated that the conflict, which has driven up prices at the pump and in supermarkets, contributed to the losses. The war has become a dividing issue even among Trump allies. Democrats aimed to capitalize on President Donald Trump's declining approval ratings. However, the state remains firmly red, joining a list of historically red states like Texas, Iowa, and Kansas that shifted toward Democrats in this cycle.
