According to Ballotpedia, Georgia's state legislature ranks the worst in the nation in the number of general election races which will go uncontested in 2016. More than 4 in 5 state legislature races will be uncontested by the opposing party this year, courtesy of winner-take-all, single-winner districts. In addition, 77.4% of incumbents who are running this year won't face a challenger in their primary.
While Georgia is the worst, this is a common trend in other state legislatures across the country. Fair representation voting methods that replace winner-take-all systems would open up every state legislature race in Georgia to competition, and give voters choices they currently are lacking.
