Background

Marty Jackley is a Republican politician from Sturgis, South Dakota, currently serving as South Dakota Attorney General and running as the Republican candidate for South Dakota's at-large U.S. House seat in the November 3, 2026 general election. He won the Republican primary on June 2, 2026, according to South Dakota Secretary of State results. 1311

Jackley earned a Bachelor of Science in electrical engineering from the South Dakota School of Mines and a law degree from the University of South Dakota. After clerking for federal judge Richard Battey, he became a partner at the Rapid City firm Gunderson, Palmer, Nelson and Ashmore, practicing criminal, civil, and complex business litigation, and served as a special assistant attorney general prosecuting controlled-substance felonies. 1

He was appointed U.S. Attorney for South Dakota in 2006 and was unanimously confirmed by the U.S. Senate, serving in that role until 2009. He was subsequently elected South Dakota Attorney General, serving from 2009 to 2019, and returned to the office in 2023 after being elected to a fourth term in 2022. 12

His campaign emphasizes his record fighting fraud and crime as attorney general and U.S. attorney, and he has written op-eds highlighting those themes as central to his congressional bid. 1419
