The 2006 Georgia gubernatorial election was held on November 7, 2006. Georgia incumbent Republican governor Sonny Perdue ran for re-election to a second and final term as governor. Governor Perdue was renominated by the Republican Party, defeating a minor opponent in the process, while Lieutenant Governor Mark Taylor narrowly emerged victorious from a competitive Democratic primary. In the general election, though Taylor ran a spirited campaign, Perdue was aided by the increasing tendency of the state to vote for Republicans and by his popularity with the public; polling showed his approval ratings above sixty percent. In the end, Perdue was overwhelmingly re-elected as governor, defeating Taylor in a landslide, becoming the first Republican Governor of Georgia to ever be reelected. As of 2024, this is the last time that Muscogee, Warren, Rockdale, Chatham, and Bibb counties voted for the Republican candidate for governor and the last time that Marion, Telfair, and Wheeler counties voted for the Democratic candidate.
