MADISON, Wisconsin: On July 26, 2012, Ballotpedia released an analysis of the rate at which incumbents are being defeated by challengers in state legislative primaries. That study was conducted roughly halfway through the primary season, and found that 76 incumbents had been defeated through the first 48 percent of primaries. After each primary, we will update those figures. This update focuses on Georgia and Texas, where a total of 15 incumbents fell to opponents on July 31, 2012.
A total of 210 Georgia legislative incumbents filed for re-election. Fifty incumbents faced a primary, and challengers were victorious in 11 of those races. Thus, 22 percent of opposed incumbents were defeated by their primary challenger.
Additionally, that night four incumbent state legislators in Texas were defeated in primary runoff races. That brought the Texas total to 11, after seven incumbents had already been defeated in the May 29, 2012 Texas primary.
The 15 total incumbents who lost on July 31 brought the nationwide figure to 91 defeated in 2012 primaries. Incumbents have been defeated in 16.16 percent of the primaries where they faced an actual opponent.
Of the 91 incumbents that have lost a primary in 2012, 27 are Democratic incumbents and 64 are Republican incumbents.
The next state legislative primary takes place tonight in Tennessee. A total of 115 seats will be on the ballot. There are 37 incumbents facing a primary opponent. We’ll have detailed results tomorrow.
