Incumbent Democratic governor Phil Bredesen was re-elected to a second term with 68.6% of the vote, defeating his Republican challenger Jim Bryson.
Improving on his performance from 2002, Bredesen also carried every county in the state.
Only Davidson, Shelby, Haywood, Hardeman, Houston, Jackson, and Lake counties have voted for a Democratic candidate in a presidential, Senate, or gubernatorial race since 2006.
Eight years after this, Republican governor Bill Haslam would win every county in the state when he won re-election.
This marked a sharp political shift in Tennessee.
