The 2006 Kansas gubernatorial election took place on November 7, 2006. Incumbent Democratic Governor Kathleen Sebelius, who sported high approval ratings ran for re-election to serve a second and final term. She was unopposed for the Democratic nomination and faced Republican State Senator Jim Barnett, who emerged from a crowded primary. Sebelius soundly defeated Barnett and cruised to re-election, which was quite a considerable feat for a Democrat in staunchly conservative Kansas. This was Sebelius's second time winning a majority and was part of a trend from 1984 to 2010 where 7 of 8 Kansas gubernatorial elections were won with a majority rather than a simple plurality. No candidate received a majority of votes in 2014, 2018 or 2022.
