Republican nominee and incumbent member of the Georgia State Senate Casey Cagle defeated Democratic nominee and former member of the Georgia House of Representatives Jim Martin and Libertarian nominee Allen Buckley.[1]
The Democratic primary election was held on 18 July 2006, but as no candidate received a majority of the vote, a run-off election was held between former member of the Georgia House of Representatives Jim Martin and former member of the Georgia State Senate Greg Hecht on 8 August 2006. Candidate Jim Martin received a majority of the votes (62.43%) in the run-off election against Hecht, and was thus elected as the nominee for the general election.[2]
The Republican primary election was held on 18 July 2006. Incumbent member of the Georgia State Senate Casey Cagle received a majority of the votes (56.05%), and was thus elected as the nominee for the general election.[3]
