On September 12, independent presidential candidate Rocky De La Fuente sued the Alabama Secretary of State, who had initially put him on the ballot, and who had then removed him after noticing that he had run in the 2016 Democratic presidential primary in Alabama. De La Fuente v Merrill, m.d., 16-cv-755. The case is assigned to U.S. District Court Judge Myron Thompson, a Carter appointee.
Alabama let Lyndon LaRouche run as an independent presidential candidate in 1992, even though LaRouche had run in the 1992 Alabama Democratic presidential primary. The sore loser law has not changed in any material way since then. It has been expanded since then to cover minor parties as well as independents, but that is not relevant to De La Fuente.
