Marsha Blackburn holds a consistent lead over Jerri Green in Tennessee’s open 2026 gubernatorial race, with recent polling averages showing a Republican advantage of roughly 9–15 points that aligns with trader expectations for a 10–20% victory margin. The state’s strong Republican tilt, reinforced by President Trump’s recent rally emphasizing party unity, underpins the baseline, while independent David Hatley’s self-funding and ballot presence risks splitting conservative votes. Green has gained modestly in Democratic-leaning surveys through targeted outreach on education and family leave, yet structural barriers limit further narrowing. Early voting and the October 27 debate among non-Republican candidates represent the final catalysts that could shift margins before November 3.
