Closest governor elections in history
129 votes decided the closest governor’s race in modern U.S. history: Washington’s 2004 contest between Christine Gregoire and Dino Rossi, out of about 2.7 million cast.
How this ranking is measured
Gubernatorial general elections ranked by the smallest gap in vote share between the top two finishers, across all 50 states. Limited to full statewide popular elections (which excludes early legislature-chosen governorships). The Washington 2004 race, decided by 133 votes after two recounts, is the modern benchmark.
