Following gains in both houses of the General Assembly in 2002 and 2004, Republicans enacted a mid-decade redistricting to alter the congressional districts created by the 146th Georgia General Assembly, which Democrats held control of at the time, with the intention of benefiting Republicans. Two Democratic incumbents who were especially targeted were Jim Marshall (GA-8) and John Barrow (GA-12). They were opposed respectively by former Representatives Mac Collins (who previously represented what is now the Third district) and Max Burns. These two races were among the most competitive in the nation, but ultimately resulted in both incumbents being re-elected by razor thin margins of 1 and 0.6 percentage points respectively.
