By FERGAL GALLAGHER, ABC News (WASHINGTON) -- A spike in disinformation about the election process in Georgia has prompted online threats against officials, poll workers and campaign staff that activists fear could lead to real-world violence. The pivotal runoff races in the state, slated for Jan. 5, hold the power of the Senate in the balance and come in the wake of a deeply divisive election cycle. Georgia went for a Democrat in the presidential race by a slim margin, prompting unsubstantiated claims of widespread fraud and attacks on Brad Raffensperger, the Republican secretary of state, who stood by the integrity of the process.
