“Like in Jacobson, the campaigns sued the secretary of state. They alleged that the secretary is the state’s chief election officer, that he has the authority and responsibility to manage Georgia’s electoral system, and that he, along with the election board members, has the duty to promulgate rules and regulations to obtain uniformity in the practices of election officials and to ensure a fair, legal, and orderly conduction of elections,” the panel wrote, referencing Jacobson v. Florida Secretary of State.
