According to Ballotpedia, there are already five other Republicans running in the Lt. Gov. primary in 2024. None of them have big statewide name recognition, as is also certainly the case with Deanna Ballard.
Ballard has put out a press release announcing her candidacy for Lt. Gov. It's a curious document in that she seems to be running pretty exclusively on re-litigating the COVID pandemic, particularly the Governor's decision to close schools, because the Republican playbook during the Trump era is all about sorehead, backward looking, not-getting-over-it resentment for any public policy meant to save lives.
Ballard also manages to embrace Mark Robinson as a guiding light in her attempt to replace him in office. Yuck.
