The 2006 Oklahoma gubernatorial election was held on November 7, 2006. Incumbent Democratic governor Brad Henry won re-election to a second term in a landslide, defeating Republican U.S. representative Ernest Istook. Henry took 66.5% of the vote to Istook's 33.5% and swept all but three counties in the state.[1]
As of 2024[update], this remains the last time that a Democrat was elected Governor of Oklahoma, or along with the concurrent elections, won any statewide office. Republicans later swept all statewide executive offices on the 2010 ballot, as they did majorities in both state legislative chambers.
