Shantel Krebs sent out an explicit challenge to Secretary of State Jason Gant in this letter to South Dakota Republican Party delegates on August 27. But in case Gant didn't check his mail at home, Krebs made sure he got the message that she wanted him out with another submission, her statement of organization of a campaign committee.
Bob Mercer finds this document on the Secretary of State's campaign finance website. Krebs indicates the office she seeks is Secretary of State. She dated the document August 30. Secretary Gant stamped it September 3.
Krebs will officially announce her candidacy for Secretary of State tomorrow.
